SOM_PAK and LVQ_PAK

Two public-domain softare packages, SOM_PAK for the Self-Organizing Map algorithm and LVQ_PAK for the Learning Vector Quantization algorithms are provided (current versions are 3.1). These program packages have been developed to demonstrate the implementation of these algorithms and to ease first experiments.

Downloading using WWW

Both program packages SOM_PAK and LVQ_PAK, as well as the reference lists are available on our www-site. Searches on the bibliography can be done on a search server.

Compiling in Microsoft Windows

The program packages were originally developed mainly for Unix. They could also be compiled for MS-DOS by using Borland C++ Version 3.1. Microsoft Windows nor other compilers have never been actively supported. It seems now that Borland has made it command line C++Builder Compiler publicly available, see http://www.borland.com/bcppbuilder/freecompiler/.

This is what you probably should set in makefile.dos in order to use it with Borland C++Builder Compiler version 5.5:

    CC = bcc32
    CFLAGS = -I/borland/bcc55/include -5 -O2 -DMSDOS
    LDFLAGS = -L/borland/bcc55/lib
