urparm, ufparm) +c parameters n, x, nf, g, uiparm, urparm, and ufparm are the same +c as for sumsl, while h is an array of length n*(n+1)/2 in which +c calcgh must store the lower triangle of the hessian at x. start- +c ing at h(1), calcgh must store the hessian entries in the order +c (1,1), (2,1), (2,2), (3,1), (3,2), (3,3), ... +c the value printed (by itsum) in the column labelled stppar +c is the levenberg-marquardt used in computing the current step. +c zero means a full newton step. if the special case described in +c ref. 1 is detected, then stppar is negated. the value printed +c in the column labelled npreldf is zero if the current hessian +c is not positive definite. +c it sometimes proves worthwhile to let d be determined from the +c diagonal of the hessian matrix by setting iv(dtype) = 1 and +c v(dinit) = 0. the following iv and v components are relevant... +c +c iv(dtol)..... iv(59) gives the starting subscript in v of the dtol +c array used when d is updated. (iv(dtol) can be +c initialized by calling humsl with iv(1) = 13.) +c iv(dtype).... iv(16) tells how the scale vector d should be chosen. +c iv(dtype) .le. 0 means that d should not be updated, and +c iv(dtype) .ge. 1 means that d should be updated as +c described below with v(dfac). default = 0. +c v(dfac)..... v(41) and the dtol and d0 arrays (see v(dtinit) and +c v(d0init)) are used in updating the scale vector d when +c iv(dtype) .gt. 0. (d is initialized according to +c v(dinit), described in sumsl.) let +c d1(i) = max(sqrt(abs(h(i,i))), v(dfac)*d(i)), +c where h(i,i) is the i-th diagonal element of the current +c hessian. if iv(dtype) = 1, then d(i) is set to d1(i) +c unless d1(i) .lt. dtol(i), in which case d(i) is set to +c max(d0(i), dtol(i)). +c if iv(dtype) .ge. 2, then d is updated during the first +c iteration as for iv(dtype) = 1 (after any initialization +c due to v(dinit)) and is left unchanged thereafter. +c default = 0.6. +c v(dtinit)... v(39), if positive, is the value to which all components +c of the dtol array (see v(dfac)) are initialized. if +c v(dtinit) = 0, then it is assumed that the caller has +c stored dtol in v starting at v(iv(dtol)). +c default = 10**-6. +c v(d0init)... v(40), if positive, is the value to which all components +c of the d0 vector (see v(dfac)) are initialized. if +c v(dfac) = 0, then it is assumed that the caller has +c stored d0 in v starting at v(iv(dtol)+n). default = 1.0. +c +c *** reference *** +c +c 1. gay, d.m.

parameter usage -------------------------- +c +c d.... scale vector. +c fx... function value. +c g.... gradient vector. +c h.... lower triangle of the hessian, stored rowwise. +c iv... integer value array. +c lh... length of h = p*(p+1)/2. +c liv.. length of iv (at least 60). +c lv... length of v (at least 78 + n*(n+21)/2). +c n.... number of variables (components in x and g). +c v.... floating-point value array. +c x.... parameter vector. +c +c *** discussion *** +c +c parameters iv, n, v, and x are the same as the corresponding +c ones to humsl (which see), except that v can be shorter (since +c the part of v that humsl uses for storing g and h is not needed). +c moreover, compared with humsl, iv(1) may have the two additional +c output values 1 and 2, which are explained below, as is the use +c of iv(toobig) and iv(nfgcal). the value iv(g), which is an +c output value from humsl, is not referenced by humit or the +c subroutines it calls. +c +c iv(1) = 1 means the caller should set fx to f(x), the function value +c at x, and call humit again, having changed none of the +c other parameters. an exception occurs if f(x) cannot be +c computed (e.g. if overflow would occur), which may happen +c because of an oversized step. in this case the caller +c should set iv(toobig) = iv(2) to 1, which will cause +c humit to ignore fx and try a smaller step. the para- +c meter nf that humsl passes to calcf (for possible use by +c calcgh) is a copy of iv(nfcall) = iv(6). +c iv(1) = 2 means the caller should set g to g(x), the gradient of f at +c x, and h to the lower triangle of h(x), the hessian of f +c at x, and call humit again, having changed none of the +c other parameters except perhaps the scale vector d. +c the parameter nf that humsl passes to calcg is +c iv(nfgcal) = iv(7). if g(x) and h(x) cannot be evaluated, +c then the caller may set iv(nfgcal) to 0, in which case +c humit will return with iv(1) = 65. +c note -- humit overwrites h with the lower triangle +c of diag(d)**-1 * h(x) * diag(d)**-1. +c. +c *** general *** +c +c coded by david m. gay (winter 1980). revised sept. 1982. +c this subroutine was written in connection with research

scale vector, i.e. the diagonal of the scale +c matrix d mentioned above under purpose. +c dig (in) = the scaled gradient vector, d**-1 * g. if g = 0, then +c step = 0 and v(stppar) = 0 are returned. +c dihdi (in) = lower triangle of the scaled hessian (approximation), +c i.e., d**-1 * h * d**-1, stored compactly by rows., i.e., +c in the order (1,1), (2,1), (2,2), (3,1), (3,2), etc. +c ka (i/o) = the number of hebden iterations (so far) taken to deter- +c mine step. ka .lt. 0 on input means this is the first +c attempt to determine step (for the present dig and dihdi) +c -- ka is initialized to 0 in this case. output with +c ka = 0 (or v(stppar) = 0) means step = -(h**-1)*g. +c l (i/o) = workspace of length p*(p+1)/2 for cholesky factors. +c p (in) = number of parameters -- the hessian is a p x p matrix. +c step (i/o) = the step computed. +c v (i/o) contains various constants and variables described below. +c w (i/o) = workspace of length 4*p + 6. +c +c *** entries in v *** +c +c v(dgnorm) (i/o) = 2-norm of (d**-1)*g. +c v(dstnrm) (output) = 2-norm of d*step. +c v(dst0) (i/o) = 2-norm of d*(h**-1)*g (for pos. def. h only), or +c overestimate of smallest eigenvalue of (d**-1)*h*(d**-1). +c v(epslon) (in) = max. rel. error allowed for psi(step). for the +c step returned, psi(step) will exceed its optimal value +c by less than -v(epslon)*psi(step). suggested value = 0.1. +c v(gtstep) (out) = inner product between g and step. +c v(nreduc) (out) = psi(-(h**-1)*g) = psi(newton step) (for pos. def. +c h only -- v(nreduc) is set to zero otherwise). +c v(phmnfc) (in) = tol. (together with v(phmxfc)) for accepting step +c (more*s sigma). the error v(dstnrm) - v(radius) must lie +c between v(phmnfc)*v(radius) and v(phmxfc)*v(radius). +c v(phmxfc) (in) (see v(phmnfc).) +c suggested values -- v(phmnfc) = -0.25, v(phmxfc) = 0.5. +c v(preduc) (out) = psi(step) = predicted obj. func. reduction for step. +c v(radius) (in) = radius of current (scaled) trust region. +c v(rad0) (i/o) = value of v(radius) from previous call. +c v(stppar) (i/o) is normally the marquardt parameter, i.e. the alpha +c described below under algorithm notes. if h + alpha*d**2 +c (see algorithm notes) is (nearly) singular, however, +c then v(stppar) = -alpha. +c +c *** usage notes *** +c +c if it is desired to recompute step using a different value of +c v(radius), then this routine may be restarted by calling it +c with all parameters unchanged except v(radius). (this explains +c why step and w are listed as i/o). on an initial call (one with +c ka .lt. 0), step and w need not be initialized and only compo- +c nents v(epslon), v(stppar), v(phmnfc), v(phmxfc), v(radius), and +c v(rad0) of v must be initialized. +c +c *** algorithm notes *** +c +c the desired g-q-t step (ref. 2, 3, 4, 6) satisfies +c (h + alpha*d**2)*step = -g for some nonnegative alpha such that +c h + alpha*d**2 is positive semidefinite. alpha and step are +c computed by a scheme analogous to the one described in ref. 5. +c estimates of the smallest and largest eigenvalues of the hessian +c are obtained from the gerschgorin circle theorem enhanced by a +c simple form of the scaling described in ref. 7. cases in which +c h + alpha*d**2 is nearly (or exactly) singular are handled by +c the technique discussed in ref. 2. in these cases, a step of +c (exact) length v(radius) is returned for which psi(step) exceeds +c its optimal value by less than -v(epslon)*psi(step). the test +c suggested in ref. 6 for detecting the special case is performed +c once two matrix factorizations have been done -- doing so sooner +c seems to degrade the performance of optimization routines that +c call this routine. +c +c *** functions and subroutines called *** +c +c dotprd - returns inner product of two vectors. +c litvmu - applies inverse-transpose of compact lower triang. matrix. +c livmul - applies inverse of compact lower triang. matrix. +c lsqrt - finds cholesky factor (of compactly stored lower triang.). +c lsvmin - returns approx. to min. sing. value of lower triang. matrix. +c rmdcon - returns machine-dependent constants. +c v2norm - returns 2-norm of a vector. +c +c *** references *** +c +c 1. dennis, j.e., gay, d.m., and welsch, r.e.

computed by calcf. (often the x* found is +c a local minimizer rather than a global one.) +c +c-------------------------- parameter usage -------------------------- +c +c n........ (input) the number of variables on which f depends, i.e., +c the number of components in x. +c d........ (input/output) a scale vector such that d(i)*x(i), +c i = 1,2,...,n, are all in comparable units. +c d can strongly affect the behavior of sumsl. +c finding the best choice of d is generally a trial- +c and-error process. choosing d so that d(i)*x(i) +c has about the same value for all i often works well. +c the defaults provided by subroutine deflt (see i +c below) require the caller to supply d. +c x........ (input/output) before (initially) calling sumsl, the call- +c er should set x to an initial guess at x*. when +c sumsl returns, x contains the best point so far +c found, i.e., the one that gives the least value so +c far seen for f(x). +c calcf.... (input) a subroutine that, given x, computes f(x). calcf +c must be declared external in the calling program. +c it is invoked by +c call calcf(n, x, nf, f, uiparm, urparm, ufparm) +c when calcf is called, nf is the invocation +c count for calcf. nf is included for possible use +c with calcg. if x is out of bounds (e.g., if it +c would cause overflow in computing f(x)), then calcf +c should set nf to 0. this will cause a shorter step +c to be attempted. (if x is in bounds, then calcf +c should not change nf.) the other parameters are as +c described above and below. calcf should not change +c n, p, or x. +c calcg.... (input) a subroutine that, given x, computes g(x), the gra- +c dient of f at x. calcg must be declared external in +c the calling program. it is invoked by +c call calcg(n, x, nf, g, uiparm, urparm, ufaprm) +c when calcg is called, nf is the invocation +c count for calcf at the time f(x) was evaluated. the +c x passed to calcg is usually the one passed to calcf +c on either its most recent invocation or the one +c prior to it. if calcf saves intermediate results +c for use by calcg, then it is possible to tell from +c nf whether they are valid for the current x (or +c which copy is valid if two copies are kept). if g +c cannot be computed at x, then calcg should set nf to +c 0. in this case, sumsl will return with iv(1) = 65. +c (if g can be computed at x, then calcg should not +c changed nf.) the other parameters to calcg are as +c described above and below. calcg should not change +c n or x. +c iv....... (input/output) an integer value array of length liv (see +c below) that helps control the sumsl algorithm and +c that is used to store various intermediate quanti- +c ties. of particular interest are the initialization/ +c return code iv(1) and the entries in iv that control +c printing and limit the number of iterations and func- +c tion evaluations. see the section on iv input +c values below. +c liv...... (input) length of iv array. must be at least 60. if li +c is too small, then sumsl returns with iv(1) = 15. +c when sumsl returns, the smallest allowed value of +c liv is stored in iv(lastiv) -- see the section on +c iv output values below. (this is intended for use +c with extensions of sumsl that handle constraints.) +c lv....... (input) length of v array. must be at least 71+n*(n+15)/2. +c (at least 77+n*(n+17)/2 for smsno, at least +c 78+n*(n+12) for humsl). if lv is too small, then +c sumsl returns with iv(1) = 16. when sumsl returns, +c the smallest allowed value of lv is stored in +c iv(lastv) -- see the section on iv output values +c below. +c v........ (input/output) a floating-point value array of length l +c (see below) that helps control the sumsl algorithm +c and that is used to store various intermediate +c quantities. of particular interest are the entries +c in v that limit the length of the first step +c attempted (lmax0) and specify convergence tolerances +c (afctol, lmaxs, rfctol, sctol, xctol, xftol). +c uiparm... (input) user integer parameter array passed without change +c to calcf and calcg. +c urparm... (input) user floating-point parameter array passed without +c change to calcf and calcg. +c ufparm... (input) user external subroutine or function passed without +c change to calcf and calcg. +c +c *** iv input values (from subroutine deflt) *** +c +c iv(1)... on input, iv(1) should have a value between 0 and 14...... +c 0 and 12 mean this is a fresh start. 0 means that +c deflt(2, iv, liv, lv, v) +c is to be called to provide all default values to iv and +c v. 12 (the value that deflt assigns to iv(1)) means the +c caller has already called deflt and has possibly changed +c some iv and/or v entries to non-default values. +c 13 means deflt has been called and that sumsl (and +c sumit) should only do their storage allocation. that is, +c they should set the output components of iv that tell +c where various subarrays arrays of v begin, such as iv(g) +c (and, for humsl and humit only, iv(dtol)), and return. +c 14 means that a storage has been allocated (by a call +c with iv(1) = 13) and that the algorithm should be +c started. when called with iv(1) = 13, sumsl returns +c iv(1) = 14 unless liv or lv is too small (or n is not +c positive). default = 12. +c iv(inith).... iv(25) tells whether the hessian approximation h should +c be initialized. 1 (the default) means sumit should +c initialize h to the diagonal matrix whose i-th diagonal +c element is d(i)**2. 0 means the caller has supplied a +c cholesky factor l of the initial hessian approximation +c h = l*(l**t) in v, starting at v(iv(lmat)) = v(iv(42)) +c (and stored compactly by rows). note that iv(lmat) may +c be initialized by calling sumsl with iv(1) = 13 (see +c the iv(1) discussion above). default = 1. +c iv(mxfcal)... iv(17) gives the maximum number of function evaluations +c (calls on calcf) allowed. if this number does not suf- +c fice, then sumsl returns with iv(1) = 9. default = 200. +c iv(mxiter)... iv(18) gives the maximum number of iterations allowed. +c it also indirectly limits the number of gradient evalua- +c tions (calls on calcg) to iv(mxiter) + 1. if iv(mxiter) +c iterations do not suffice, then sumsl returns with +c iv(1) = 10. default = 150. +c iv(outlev)... iv(19) controls the number and length of iteration sum- +c mary lines printed (by itsum). iv(outlev) = 0 means do +c not print any summary lines. otherwise, print a summary +c line after each abs(iv(outlev)) iterations. if iv(outlev) +c is positive, then summary lines of length 78 (plus carri- +c age control) are printed, including the following... the +c iteration and function evaluation counts, f = the current +c function value, relative difference in function values +c achieved by the latest step (i.e., reldf = (f0-v(f))/f01, +c where f01 is the maximum of abs(v(f)) and abs(v(f0)) and +c v(f0) is the function value from the previous itera- +c tion), the relative function reduction predicted for the +c step just taken (i.e., preldf = v(preduc) / f01, where +c v(preduc) is described below), the scaled relative change +c in x (see v(reldx) below), the step parameter for the +c step just taken (stppar = 0 means a full newton step, +c between 0 and 1 means a relaxed newton step, between 1 +c and 2 means a double dogleg step, greater than 2 means +c a scaled down cauchy step -- see subroutine dbldog), the +c 2-norm of the scale vector d times the step just taken +c (see v(dstnrm) below), and npreldf, i.e., +c v(nreduc)/f01, where v(nreduc) is described below -- if +c npreldf is positive, then it is the relative function +c reduction predicted for a newton step (one with +c stppar = 0). if npreldf is negative, then it is the +c negative of the relative function reduction predicted +c for a step computed with step bound v(lmaxs) for use in +c testing for singular convergence. +c if iv(outlev) is negative, then lines of length 50 +c are printed, including only the first 6 items listed +c above (through reldx). +c default = 1. +c iv(parprt)... iv(20) = 1 means print any nondefault v values on a +c fresh start or any changed v values on a restart. +c iv(parprt) = 0 means skip this printing. default = 1. +c iv(prunit)... iv(21) is the output unit number on which all printing +c is done. iv(prunit) = 0 means suppress all printing. +c default = standard output unit (unit 6 on most systems). +c iv(solprt)... iv(22) = 1 means print out the value of x returned (as +c well as the gradient and the scale vector d). +c iv(solprt) = 0 means skip this printing. default = 1. +c iv(statpr)... iv(23) = 1 means print summary statistics upon return- +c ing. these consist of the function value, the scaled +c relative change in x caused by the most recent step (see +c v(reldx) below), the number of function and gradient +c evaluations (calls on calcf and calcg), and the relative +c function reductions predicted for the last step taken and +c for a newton step (or perhaps a step bounded by v(lmaxs) +c -- see the descriptions of preldf and npreldf under +c iv(outlev) above). +c iv(statpr) = 0 means skip this printing. +c iv(statpr) = -1 means skip this printing as well as that +c of the one-line termination reason message. default = 1. +c iv(x0prt).... iv(24) = 1 means print the initial x and scale vector d +c (on a fresh start only). iv(x0prt) = 0 means skip this +c printing. default = 1. +c +c *** (selected) iv output values *** +c +c iv(1)........ on output, iv(1) is a return code.... +c 3 = x-convergence. the scaled relative difference (see +c v(reldx)) between the current parameter vector x and +c a locally optimal parameter vector is very likely at +c most v(xctol). +c 4 = relative function convergence. the relative differ- +c ence between the current function value and its lo- +c cally optimal value is very likely at most v(rfctol). +c 5 = both x- and relative function convergence (i.e., the +c conditions for iv(1) = 3 and iv(1) = 4 both hold). +c 6 = absolute function convergence. the current function +c value is at most v(afctol) in absolute value. +c 7 = singular convergence. the hessian near the current +c iterate appears to be singular or nearly so, and a +c step of length at most v(lmaxs) is unlikely to yield +c a relative function decrease of more than v(sctol). +c 8 = false convergence. the iterates appear to be converg- +c ing to a noncritical point. this may mean that the +c convergence tolerances (v(afctol), v(rfctol), +c v(xctol)) are too small for the accuracy to which +c the function and gradient are being computed, that +c there is an error in computing the gradient, or that +c the function or gradient is discontinuous near x. +c 9 = function evaluation limit reached without other con- +c vergence (see iv(mxfcal)). +c 10 = iteration limit reached without other convergence +c (see iv(mxiter)). +c 11 = stopx returned .true. (external interrupt). see the +c usage notes below. +c 14 = storage has been allocated (after a call with +c iv(1) = 13). +c 17 = restart attempted with n changed. +c 18 = d has a negative component and iv(dtype) .le. 0. +c 19...43 = v(iv(1)) is out of range. +c 63 = f(x) cannot be computed at the initial x. +c 64 = bad parameters passed to assess (which should not +c occur). +c 65 = the gradient could not be computed at x (see calcg +c above). +c 67 = bad first parameter to deflt. +c 80 = iv(1) was out of range. +c 81 = n is not positive. +c iv(g)........ iv(28) is the starting subscript in v of the current +c gradient vector (the one corresponding to x). +c iv(lastiv)... iv(44) is the least acceptable value of liv. (it is +c only set if liv is at least 44.) +c iv(lastv).... iv(45) is the least acceptable value of lv. (it is +c only set if liv is large enough, at least iv(lastiv).) +c iv(nfcall)... iv(6) is the number of calls so far made on calcf (i.e., +c function evaluations). +c iv(ngcall)... iv(30) is the number of gradient evaluations (calls on +c calcg). +c iv(niter).... iv(31) is the number of iterations performed. +c +c *** (selected) v input values (from subroutine deflt) *** +c +c v(bias)..... v(43) is the bias parameter used in subroutine dbldog -- +c see that subroutine for details. default = 0.8. +c v(afctol)... v(31) is the absolute function convergence tolerance. +c if sumsl finds a point where the function value is less +c than v(afctol) in absolute value, and if sumsl does not +c return with iv(1) = 3, 4, or 5, then it returns with +c iv(1) = 6. this test can be turned off by setting +c v(afctol) to zero. default = max(10**-20, machep**2), +c where machep is the unit roundoff. +c v(dinit).... v(38), if nonnegative, is the value to which the scale +c vector d is initialized. default = -1. +c v(lmax0).... v(35) gives the maximum 2-norm allowed for d times the +c very first step that sumsl attempts. this parameter can +c markedly affect the performance of sumsl. +c v(lmaxs).... v(36) is used in testing for singular convergence -- if +c the function reduction predicted for a step of length +c bounded by v(lmaxs) is at most v(sctol) * abs(f0), where +c f0 is the function value at the start of the current +c iteration, and if sumsl does not return with iv(1) = 3, +c 4, 5, or 6, then it returns with iv(1) = 7. default = 1. +c v(rfctol)... v(32) is the relative function convergence tolerance. +c if the current model predicts a maximum possible function +c reduction (see v(nreduc)) of at most v(rfctol)*abs(f0) +c at the start of the current iteration, where f0 is the +c then current function value, and if the last step attempt- +c ed achieved no more than twice the predicted function +c decrease, then sumsl returns with iv(1) = 4 (or 5). +c default = max(10**-10, machep**(2/3)), where machep is +c the unit roundoff. +c v(sctol).... v(37) is the singular convergence tolerance -- see the +c description of v(lmaxs) above. +c v(tuner1)... v(26) helps decide when to check for false convergence. +c this is done if the actual function decrease from the +c current step is no more than v(tuner1) times its predict- +c ed value. default = 0.1. +c v(xctol).... v(33) is the x-convergence tolerance. if a newton step +c (see v(nreduc)) is tried that has v(reldx) .le. v(xctol) +c and if this step yields at most twice the predicted func- +c tion decrease, then sumsl returns with iv(1) = 3 (or 5). +c (see the description of v(reldx) below.) +c default = machep**0.5, where machep is the unit roundoff. +c v(xftol).... v(34) is the false convergence tolerance. if a step is +c tried that gives no more than v(tuner1) times the predict- +c ed function decrease and that has v(reldx) .le. v(xftol), +c and if sumsl does not return with iv(1) = 3, 4, 5, 6, or +c 7, then it returns with iv(1) = 8. (see the description +c of v(reldx) below.) default = 100*machep, where +c machep is the unit roundoff. +c v(*)........ deflt supplies to v a number of tuning constants, with +c which it should ordinarily be unnecessary to tinker. see +c section 17 of version 2.2 of the nl2sol usage summary +c (i.e., the appendix to ref. 1) for details on v(i), +c i = decfac, incfac, phmnfc, phmxfc, rdfcmn, rdfcmx, +c tuner2, tuner3, tuner4, tuner5. +c +c *** (selected) v output values *** +c +c v(dgnorm)... v(1) is the 2-norm of (diag(d)**-1)*g, where g is the +c most recently computed gradient. +c v(dstnrm)... v(2) is the 2-norm of diag(d)*step, where step is the +c current step. +c v(f)........ v(10) is the current function value. +c v(f0)....... v(13) is the function value at the start of the current +c iteration. +c v(nreduc)... v(6), if positive, is the maximum function reduction +c possible according to the current model, i.e., the func- +c tion reduction predicted for a newton step (i.e., +c step = -h**-1 * g, where g is the current gradient and +c h is the current hessian approximation). +c if v(nreduc) is negative, then it is the negative of +c the function reduction predicted for a step computed with +c a step bound of v(lmaxs) for use in testing for singular +c convergence. +c v(preduc)... v(7) is the function reduction predicted (by the current +c quadratic model) for the current step. this (divided by +c v(f0)) is used in testing for relative function +c convergence. +c v(reldx).... v(17) is the scaled relative change in x caused by the +c current step, computed as +c max(abs(d(i)*(x(i)-x0(i)), 1 .le. i .le. p) / +c max(d(i)*(abs(x(i))+abs(x0(i))), 1 .le. i .le. p), +c where x = x0 + step. +c +c------------------------------- notes ------------------------------- +c +c *** algorithm notes *** +c +c this routine uses a hessian approximation computed from the +c bfgs update (see ref 3). only a cholesky factor of the hessian +c approximation is stored, and this is updated using ideas from +c ref. 4. steps are computed by the double dogleg scheme described +c in ref. 2. the steps are assessed as in ref. 1. +c +c *** usage notes *** +c +c after a return with iv(1) .le. 11, it is possible to restart, +c i.e., to change some of the iv and v input values described above +c and continue the algorithm from the point where it was interrupt- +c ed. iv(1) should not be changed, nor should any entries of i +c and v other than the input values (those supplied by deflt). +c those who do not wish to write a calcg which computes the +c gradient analytically should call smsno rather than sumsl. +c smsno uses finite differences to compute an approximate gradient. +c those who would prefer to provide f and g (the function and +c gradient) by reverse communication rather than by writing subrou- +c tines calcf and calcg may call on sumit directly. see the com- +c ments at the beginning of sumit. +c those who use sumsl interactively may wish to supply their +c own stopx function, which should return .true. if the break key +c has been pressed since stopx was last invoked. this makes it +c possible to externally interrupt sumsl (which will return with +c iv(1) = 11 if stopx returns .true.). +c storage for g is allocated at the end of v. thus the caller +c may make v longer than specified above and may allow calcg to use +c elements of g beyond the first n as scratch storage. +c +c *** portability notes *** +c +c the sumsl distribution tape contains both single- and double- +c precision versions of the sumsl source code, so it should be un- +c necessary to change precisions. +c only the functions imdcon and rmdcon contain machine-dependent +c constants. to change from one machine to another, it should +c suffice to change the (few) relevant lines in these functions. +c intrinsic functions are explicitly declared. on certain com- +c puters (e.g. univac), it may be necessary to comment out these +c declarations. so that this may be done automatically by a simple +c program, such declarations are preceded by a comment having c/+ +c in columns 1-3 and blanks in columns 4-72 and are followed by +c a comment having c/ in columns 1 and 2 and blanks in columns 3-72. +c the sumsl source code is expressed in 1966 ansi standard +c fortran. it may be converted to fortran 77 by commenting out all +c lines that fall between a line having c/6 in columns 1-3 and a +c line having c/7 in columns 1-3 and by removing (i.e., replacing +c by a blank) the c in column 1 of the lines that follow the c/7 +c line and precede a line having c/ in columns 1-2 and blanks in +c columns 3-72. these changes convert some data statements into +c parameter statements, convert some variables from real to +c character*4, and make the data statements that initialize these +c variables use character strings delimited by primes instead +c of hollerith constants. (such variables and data statements +c appear only in modules itsum and parck. parameter statements +c appear nearly everywhere.) these changes also add save state- +c ments for variables given machine-dependent constants by rmdcon. +c +c *** references *** +c +c 1. dennis, j.e., gay, d.m., and welsch, r.e.

v.... floating-point value array. +c x.... vector of parameters to be optimized. +c +c *** discussion *** +c +c parameters iv, n, v, and x are the same as the corresponding +c ones to sumsl (which see), except that v can be shorter (since +c the part of v that sumsl uses for storing g is not needed). +c moreover, compared with sumsl, iv(1) may have the two additional +c output values 1 and 2, which are explained below, as is the use +c of iv(toobig) and iv(nfgcal). the value iv(g), which is an +c output value from sumsl (and smsno), is not referenced by +c sumit or the subroutines it calls. +c fx and g need not have been initialized when sumit is called +c with iv(1) = 12, 13, or 14. +c +c iv(1) = 1 means the caller should set fx to f(x), the function value +c at x, and call sumit again, having changed none of the +c other parameters. an exception occurs if f(x) cannot be +c (e.g. if overflow would occur), which may happen because +c of an oversized step. in this case the caller should set +c iv(toobig) = iv(2) to 1, which will cause sumit to ig- +c nore fx and try a smaller step. the parameter nf that +c sumsl passes to calcf (for possible use by calcg) is a +c copy of iv(nfcall) = iv(6). +c iv(1) = 2 means the caller should set g to g(x), the gradient vector +c of f at x, and call sumit again, having changed none of +c the other parameters except possibly the scale vector d +c when iv(dtype) = 0. the parameter nf that sumsl passes +c to calcg is iv(nfgcal) = iv(7). if g(x) cannot be +c evaluated, then the caller may set iv(nfgcal) to 0, in +c which case sumit will return with iv(1) = 65. +c. +c *** general *** +c +c coded by david m. gay (december 1979). revised sept. 1982. +c this subroutine was written in connection with research supported +c in

scheme (ref. 2, p. 95). +c +c-------------------------- parameter usage -------------------------- +c +c dig (input) diag(d)**-2 * g -- see algorithm notes. +c g (input) the current gradient vector. +c lv (input) length of v. +c n (input) number of components in dig, g, nwtstp, and step. +c nwtstp (input) negative newton step -- see algorithm notes. +c step (output) the computed step. +c v (i/o) values array, the following components of which are +c used here... +c v(bias) (input) bias for relaxed newton step, which is v(bias) of +c the way from the full newton to the fully relaxed newton +c step. recommended value = 0.8 . +c v(dgnorm) (input) 2-norm of diag(d)**-1 * g -- see algorithm notes. +c v(dstnrm) (output) 2-norm of diag(d) * step, which is v(radius) +c unless v(stppar) = 0 -- see algorithm notes. +c v(dst0) (input) 2-norm of diag(d) * nwtstp -- see algorithm notes. +c v(grdfac) (output) the coefficient of dig in the step returned -- +c step(i) = v(grdfac)*dig(i) +

means a +c full newton step. between 0 and 1 means v(stppar) of the +c way from the newton to the relaxed newton step. between +c 1 and 2 means a true double dogleg step, v(stppar) - 1 of +c the way from the relaxed newton to the cauchy step. +c greater than 2 means 1 / (v(stppar) - 1) times the cauchy +c step. +c +c------------------------------- notes ------------------------------- +c +c *** algorithm notes *** +c +c let g and h be the current gradient and hessian approxima- +c tion respectively and let d be the current scale vector. this +c routine assumes dig = diag(d)**-2 * g and nwtstp = h**-1 * g. +c the step computed is the same one would get by replacing g and h +c by diag(d)**-1 * g and diag(d)**-1 * h * diag(d)**-1, +c computing step, and translating step back to the original +c variables, i.e., premultiplying it by diag(d)**-1. +c +c *** references *** +c +c 1. dennis, j.e., and mei, h.h.w.
