Genetic algorithm inspired by gene duplication
H. Sawai, S. Adachi · 2003
Gene duplication theory was first proposed by a Japanese biologist, Dr. Susumu Ohno, in the 1970s. Inspired by the theory, we develop a gene duplicated genetic algorithm. Several variants for this algorithm are considered. Individuals with various lengths of genes are evolved based on a parameter-free genetic algorithm and then genes with different lengths are concatenated by migrating among subpopulations. To verify the effectiveness of the gene duplicated genetic algorithm, we performed a comparative study using function optimization problems from the first ICEO (International Contest on Evolutionary Optimization) held in 1996.
