2009-07-11 Brian Gough <bjg@network-theory.co.uk>
* quad_golden.c: added new safeguarded step-length algorithm from
James Howse
2009-07-09 Brian Gough <bjg@network-theory.co.uk>
* fsolver.c (gsl_min_fminimizer_free): handle NULL argument in free
2008-07-03 Brian Gough <bjg@hp2.network-theory.co.uk>
* Makefile.am (INCLUDES): use top_srcdir instead of top_builddir
2008-01-09 Brian Gough <bjg@network-theory.co.uk>
* brent.c (brent_iterate): remove spurious early return
2007-07-30 Brian Gough <bjg@network-theory.co.uk>
* min.h (SAFE_FUNC_CALL): use gsl_finite instead of finite
2005-09-09 Brian Gough <bjg@network-theory.co.uk>
* min.h: improved error message, function can be discontinuous
despite what error message said.
2005-04-28 Brian Gough <bjg@network-theory.co.uk>
* brent.c (brent_iterate): fixed error in ordering of tests for
updates so that it agrees with Brent's book.
2004-04-13 Brian Gough <bjg@network-theory.co.uk>
* brent.c (brent_iterate): corrected condition for setting to
+/-tolerance.
Sun Apr 7 15:22:11 2002 Brian Gough <bjg@network-theory.co.uk>
* fsolver.c (gsl_min_fminimizer_x_minimum): new function,
obsoletes gsl_min_fminimizer_minimum.
(gsl_min_fminimizer_f_minimum): new function for accessing
function values
(gsl_min_fminimizer_f_lower): new function for accessing function
values
(gsl_min_fminimizer_f_upper): new function for accessing function
values
* renamed minimum to x_minimum throughout
Wed Oct 3 11:35:45 2001 Brian Gough <bjg@network-theory.co.uk>
* test.c (main): added an extra test
Sun Jul 15 17:53:26 2001 Brian Gough <bjg@network-theory.co.uk>
* eliminated interval type, changed order of arguments to set
functions
Tue Apr 17 22:13:58 2001 Brian Gough <bjg@network-theory.co.uk>
* fsolver.c (gsl_min_fminimizer_alloc): removed unnecessary status
variable
Mon Apr 2 14:54:33 2001 Brian Gough <bjg@network-theory.co.uk>
* brent.c (brent_init): fixed incorrect value for golden ratio
(brent_iterate): fixed incorrect value for golden ratio
* golden.c (goldensection_iterate): fixed incorrect value for
golden ratio
* bracketing.c (gsl_min_find_bracket): fixed incorrect value for
golden ratio
Sun Feb 18 11:43:04 2001 Brian Gough <bjg@network-theory.co.uk>
* fsolver.c: changed so that the solver _alloc function no longer
calls _set, the user must do that separately.
Fri May 5 16:09:11 2000 Brian Gough <bjg@network-theory.co.uk>
* test.c (test_bracket): fixed warning about "control reaches end
of non-void function" by changing return type to void
Tue Feb 15 16:32:55 2000 Brian Gough <bjg@network-theory.co.uk>
* bracketing.c (gsl_min_find_bracket): changed counter nb_eval
from type int to type size_t in order to avoid comparison between
signed and unsigned, (nb_eval < eval_max).
Mon Feb 14 13:07:43 2000 Brian Gough <bjg@network-theory.co.uk>
* made all internal functions static
Wed Oct 13 16:08:03 1999 Brian Gough <bjg@network-theory.co.uk>
* rewritten to allow initial values to be specified
