GAUL Ported to Open Watcom Compiler

GAUL is now ported to the Open Watcom C/C++ compiler.

All files required for building GAUL with the Open Watcom compiler and IDE are provided in the "Watcom" subdirectory of the GAUL source code package. This is tested with Open Watcom version 1.7a.

Further details are available about GAUL on Open Watcom: http://saa.dyndns.org/stewart/Software/Gaul/GaulNews/GaulPortedToOpenWatcom.html

Visual Studio solution for GAUL

Solution and project files for Microsoft Visual Studio are now included in the GAUL CVS archive.

Microsoft Windows is now a fully supported platform for GAUL. GAUL has always been readily portable, but now it is more immediately useful for developers of Windows software, or of other portable software that also needs to support Windows.

The CVS archive may be browsed from:

GAUL with Perl!

A new package, gaul-perl, has been added to the CVS archive. This is a set of prototype wrappers around the GAUL library for Perl.

While it is still far from complete and highly experimently, it is functional for simple GA calculations. This is demonstrated by the included struggle.pl script which is a direct port of the struggle.c example from the main GAUL distribution. When complete, the number of supported scripting languages will be brought to three (along with the built-in support for S-Lang, and the propriety gaul-svl wrappers for SVL).... read more

Compiling GAUL on Windows.

A Windows port of the GAUL sourcecode is now available for download. This source code is distributed with instructions for compilation with Microsoft Visual C++ and the Bloodshed Dev-C++ IDE.

This Windows port is almost feature-complete with respect to the original UNIX code-base.

The download is available at:
http://prdownloads.sourceforge.net/gaul/gaul-devel-windows.zip?download

Further information is available from:

New GAUL release (version 0.1848)

The GAUL project announces the latest release of GAUL - the Genetic Algorithm Utility Library, a leading open-source programming library for evolutionary computation. GAUL version 0.1848 contains a significant number of improvements and additions.

Since the prior release, significant work has been applied for clean compilation with recent compilers, and straightforward installation on modern computer systems. This has been facilitated through testing on several supercomputers and large clusters. The GAUL developers thank the individuals and organisation who have made this possible.... read more

x86_64 and alpha binaries available

64-bit GAUL binaries for use on AMD64 (x86_64) and Alpha platforms are now available for download.

Further binaries for Sparc64, MIPS, Power3/4/5, and probably others could be made available upon demand.

Now, who has an IA64 machine that I could borrow? ;-)

Release 0.1843 of GAUL released

The current development cycle has seen lots of behind-the-scenes code tidying and fixes. All users of GAUL are encouraged to upgrade to this version, although this will require the two minor changes detailed below.

The following new features are available:

- ga_fitness_mean() function to provide additional statistics on the population.
- ga_population_get_generation() function to access the generation number from within the callbacks used during evolution, e.g. the fitness evaluation function.
- A new elitism option, GA_ELITISM_RESCORE_PARENTS. This re-evaluates the parents' fitness and maintains them in the population if they still have a sufficiently high fitness.... read more

Release 0.1842 of GAUL now available

The main additions to this release are much improved non-evolutionary heuristic algorithms. This release has been tested on a range of platforms, including Linux, Solaris, and FreeBSD.

Significant changes:
- Numerous fixes for compilation with MingW ( http://www.mingw.org/ ) for Windows and some minor fixes for clean compilation on Solaris and FreeBSD.
- Added a kludge to avoid problem with "OpenMOSIX weird bus error bug".
- Hill climbing (random ascent and next ascent) code completely rewritten. Added
simplex search, random search, systematic search, and steepest ascents algorithms along with some examples.
