Abstract
This paper describes Self-OrganizingMaps for Genetic Algorithm (SOM-GA). In
this algorithm, the search performance of a real-coded genetic algorithm (RCGA)
is enhanced with self-organizing map (SOM). The SOM is trained with the information
of the individuals in the population. Sub-populations are generated from
a whole population by the help of the map. The RCGA search is performed in
the sub-populations. The Rastrigin function is considered as a test problem. The
search performance of SOM-GA is compared with that of the RCGA. The results
show that the use of the sub-population search algorithm improves the local search
performance of the RCGA and therefore, SOM-GA can find better solutions in
shorter CPU time than RCGA.
Keywords: real-coded genetic algorithms, self-organizing maps, Rastrigin function.
