PREPROCESSOR DIRECTIVES
Here are the preprocessor directives that the library understands. If you
are using a makefile, then put these in the line with the DEFINES macro. For
example, to define the NO_TEMPLATES and USE_BORLAND_INST options then do
DEFINES = -DNO_TEMPLATES -DUSE_BORLAND_INST
In MacOS or DOS, use your development environment's preprocessor directives
option to set the values. Beware that if you use the makefile or your
development environment to do the defines then someone may compile a program
later on that does not use the same defines you used to compile the library.
For best results (ie smallest chance of error), modify this header file
rather than using the makefile or development environment.
Some of these are already set up for the OSes with which I am familiar. See
below for the pre-defined sets. If you come up with a compiler/platform
configuration that is not listed here, please send it to me so that i can
incorporate it into the code base.
USE_ANSI_STREAMS For systems/environments in which streams are not desired
USE_OLD_STREAMS and/or required. Turns off errors and all of the read/
NO_STREAMS write routines for the classes when neither of these is
defined or when NO_STREAMS is defined.
USE_CPP_CASTS If your compiler supports RTTI, or if you turn on
USE_RTTI the RTTI abilities of your compiler, then define these
macros. Without RTTI, if improper casts are made,
things will die horribly rather than dropping out in an
RTTI-induced exception.
USE_PID Define this if the system has a getpid function that
returns something sane and useful.
NO_TEMPLATES For compilers that do not do templates. The only type
of genome available when this is defined is binary
string and any derived classes. list, tree, and array
all use templates. You can still use the template code,
but you will have to hack it yourself to make it work.
USE_BORLAND_INST For compilers that use the Borland instantiation model.
These compilers expect all of the template code to be
in the header file. The Cfront model, on the other
hand, expects source files with names similar to the
header files, but all of the template code does not
need to be in the header files.
When you define this flag, the source file that
corresponds to the header file is explicitly included
at the end of the header file for all headers that
contain templates.
USE_AUTO_INST For compilers that do not do automatic instantiation
(such as g++ version 2.6.8) you will have to force
instantiations. When this flag is not defined, GAlib
forces an instantiation of all of the template classes
that it uses (such as real genome and string genome).
USE_RAN1 These specify which random number function to use. Only
USE_RAN2 one of these may be specified. You may have to tweak
USE_RAN3 random.h a bit as well (these functions are not defined
USE_RAND the same way on each platform). For best results, use
USE_RANDOM ran2 or ran3 (performance is slightly slower than most
USE_RAND48 system RNGs, but you'll get better results).
If you want to use another random number generator you
must hack random.h directly (see the comments in that
file).
BITBASE The built-in type to use for bit conversions. This
should be set to the type of the largest integer that
your system supports. If you have long long int then
use it. If you don't plan to use more than 16 or 32
bits to represent your binary-to-decimal mappings then
you can use something smaller (long int for example).
If you do not set this, GAlib will automatically use
the size of a long int. The bitbase determines the
maximum number of bits you can use to represent a
decimal number in the binary-to-decimal genomes.
BITS_IN_WORD How many bits are in a word? For many systems, a word is
a char and is 8 bits long.

SPACE SAVERS and DEFAULT OPERATORS
These directives determine which operators will be used by default for each
of the objects in GAlib.
If space is limited, you may want to compile the library with only the parts
that you need (compiling in DOS comes to mind). Your compiler should do this
automatically for you (ie only use the parts that you use). If not, then
comment out the chunks in the files you're not going to use (for example,
comment out the ordered initializer in the list object).
To disable a certain type of genome, simply don't compile its source file.
The following directives are defined so that you can trim out the parts of the
genetic algorithm objects that are not in separate files.
