| |
| * 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 |
| |

| |
| * 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. |
