A study on the effect of transfer of genes for the bacterial evolutionary algorithm

Abstract

This paper presents a study on the effect of transfer of genes for bacterial evolutionary algorithm. The bacterial operation, in the pseudo-bacterial genetic algorithm (PBGA) is efficient in improving local portions of chromosomes. In the experiments presented a gene transfer operation is introduced in the place of the crossover operation in the PBGA. The gene transfer operation allows the chromosomes to directly transfer information to the other counterparts in the population. The gene transfer is inspired by the phenomenon of transfer of strands of genes between bacteria that occurs in nature. By means of this mechanism. One bacterium can rapidly spread its genetic information to other cells. Numerical experiments were performed to show the effectiveness of the PBGA with the gene transfer operation. The obtained results show the benefits that can be obtained with the newly introduced operation.
