========================================================================
10 Jan 97

asa.c, asa_user.h, readme.ms, user.c:
In asa_user.h, the OPTIONS *Best_Cost and *Best_Parameters are pointers
to the saved best state calculated in asa(), and Locate_Cost is set to
12 instead of 2 if newly generated parameters enter the cost function
just after a new best state is achieved.  The ASA_TEMPLATE just after
the comment MY_TEMPLATE_diminishing_ranges in user.c illustrates the
use.

asa.c, asa_user.h, readme.ms, user.c:
Similarly, in asa_user.h, the OPTIONS *Last_Cost (replacing Last_Cost,
used when USER_ACCEPTANCE_TEST is TRUE) and *Last_Parameters are
pointers to the last saved state calculated in asa().

When USER_GENERATING_FUNCTION is true, the functions defined by
Generating_Distrib [user_generating_distrib(), and
recur_user_generating_distrib() if SELF_OPTIMIZE is TRUE] include the
passed array last_saved_parameter[].  This array contains all the last
saved parameters, which are sometimes required for algorithms requiring
decisions based on all current parameters.

========================================================================
10 June 96

asa.c, asa_user.h, readme.ms, user.c:
Changed all occurrences of MY_COST in user.c to distinct names of type
MY_TEMPLATE_[...] to aid user-defined insertions of code in user.c and
in asa_user.h when MY_TEMPLATE is set to TRUE (the default).

========================================================================
9 Jun 96

readme.ms, user.c:
If the value of seed fed to asa_seed() is less than 0, this signals the
default randflt() to initialize the array of seeds to be shuffled.
This is especially useful when using repeated calls to asa_main() when
ASA_LIB is TRUE.

asa.c:
Corrected bug in testing whether to bypass derivative calculations in
asa_exit().

========================================================================

Makefile, asa.c, asa_user.h, user.c, readme.ms:
When USER_ACCEPT_ASYMP_EXP is TRUE, an asymptotic form of the
exponential function as an alternative to the Boltzmann function
becomes available for the acceptance test.  A parameter
OPTIONS->Asymp_Exp_Param becomes available, with a default of 1.0
giving the standard Boltzmann function.

========================================================================
19 Apr 96

asa.c:
Made index_cost_constraint available when either USER_INITIAL_COST_TEMP
or USER_REANNEAL_COST is FALSE, and corrected test on
User_Cost_Temperature.

Corrected some archive addresses.

========================================================================
10 Apr 96

Makefile, asa.c, asa.h, asa_user.h, readme.ms:
Moved MIN_EXPONENT and MAX_EXPONENT from static variables in asa.c to
#define's in asa.h.  When CHECK_EXPONENT is TRUE, EXPONENT_CHECK(x) in
asa() checks that an exponent x is within a valid range and, if not,
adjusts its magnitude to fit in the range.

========================================================================
8 Apr 96

user.c:
Changed rand_seed to recur_rand_seed when ASA_TEMPLATE_SELFOPT is TRUE.

Cleaned up a few typos.

========================================================================
