2006-03-08 Brian Gough <bjg@network-theory.co.uk>
* test.c (square): removed inline since it causes problems with
some compilers
2005-11-14 Brian Gough <bjg@network-theory.co.uk>
* siman.c (safe_exp): added a safe_exp function to avoid underflow
for large uphill steps
2003-03-31 Brian Gough <bjg@network-theory.co.uk>
* siman.c (gsl_siman_solve): avoid reevaluation for best_E
(gsl_siman_solve): loop over param.iters_fixed_T not
params.n_tries
(gsl_siman_solve): initialise energy at start
Sat Aug 3 20:32:38 2002 Brian Gough <bjg@network-theory.co.uk>
* siman.c (gsl_siman_solve): fix acceptance criterion to match
documentation (Peter S. Christopher)
Thu Jun 13 20:57:00 2002 Brian Gough <bjg@network-theory.co.uk>
* siman.c (gsl_siman_solve): keep track of the best result
2002-02-07 Mark Galassi <rosalia@galassi.org>
* siman.c (gsl_siman_solve): bug fix in the destructor for x and
new_x which was being called on &x and &new_x instead of x and
new_x; thanks to Karsten Howes <karsten@videotron.ca>
Thu Jul 12 21:50:07 2001 Brian Gough <bjg@network-theory.co.uk>
* gsl_siman.h: changed renamed gsl_Efunc_t to gsl_siman_Efunc_t,
in accordance with namespace conventions
2000-12-15 Mark Galassi <rosalia@galassi.org>
* siman.c (gsl_siman_solve): reversed a small change I had made
earlier and went back to taking Boltzmann-conditional steps when
the new energy is equal to the previous one. This allows you to
move around if you are stuck on a plateau.
* gsl_siman.h, siman.c, siman_test.c, siman_tsp.c, test.c: changed
the siman_solve API to allow for more general search spaces. The
problem was that we assumed that points in the search space were
data structures that were allocated in continguous memory, so they
could not be linked structures. I replaced the malloc(), memcpy()
and free() calls with copy_constructor(), copyfunc() and
copy_destructor() functions. The user passes these functions,
which means that siman_solve() now takes three more arguments of
type gsl_siman_copy_t, gsl_siman_copy_construct_t and
gsl_siman_destroy_t. If these arguments are NULL (and all three
of them have to be NULL together), the traditional memcpy()
approach is used.

* minor fixes.
Tue Nov 17 17:22:14 1998 Brian Gough <bjg@vvv.lanl.gov>
* added #include <config.h> to all top-level source files
Sun Nov 8 20:40:28 1998 Brian Gough <bjg@vvv.lanl.gov>
* siman_tsp.c: clean up for make strict
1998-11-06 <bjg@ancho.lanl.gov>
* test.c: added prototype for memcpy using #include <string.h>
* siman_test.c: added prototype for memcpy using #include <string.h>
Wed Oct 28 15:06:58 1998 Brian Gough <bjg@vvv.lanl.gov>
* siman.c: added #include <string.h> for memcpy
Thu Aug 20 12:22:28 1998 Brian Gough <bjg@vvv.lanl.gov>
* siman.c: use (char *) judiciously to avoid warnings about void
pointer arithmetic (see randist/shuffle.c for similar examples)
* siman_test.c: perform several tests, using the exact answer as
the comparison value, rather than checking for stationarity.
Sun Jun 28 14:11:04 1998 Brian Gough <bjg@vvv.lanl.gov>
* Converted to work with rng-style random number generators
* gsl_siman.h: gsl_siman_step_t type functions now take a gsl_rng
random number generator as their first argument
* siman.c (gsl_siman_solve): Now takes a gsl_rng random number
generator as the first argument
Fri Jun 19 11:17:24 1998 Brian Gough <bjg@vvv.lanl.gov>
* siman.c (gsl_siman_solve_many): changed the variable 'throw' to
'u' (for uniform-random-number) so that we can compile with c++
where throw is a reserved word.
Sat May 23 13:59:55 1998 Brian Gough <bjg@vvv.lanl.gov>
* siman.c: made the solving functions deterministic by removing
the random seed, gsl_ran_seed(time(0L)). When the function is
non-deterministic it is hard to debug and test (about 1 time in 20
the test would fail due to the randomness). We can let the user do
the seeding if they need that.
1998-02-09 Mark Galassi <rosalia@nis.lanl.gov>
* siman_test_driver.sh (LAST_ENERGY): fixed a typo; the tests now
report well when they converge.
1998-01-30 Mark Galassi <rosalia@cygnus.com>
* siman_test_driver.sh, Makefile.am (TESTS): added a test driver
so that now "make check" does something interesting.
