Abstract
The gene exchange method in the inversion of GA is categorized into three types. Three modes show three different patterns about the exchange probability of genes, and the exchange probabilities of genes depend on their locations, except mode 3. In mode 1, gene exchange probability in the center area is higher than in the ends. In mode 2, gene exchange probability in the center area is smaller than in the ends. In mode 3, the exchange probability of genes does not depend on the location of those loci. The calculated results of gene exchange probability show clear agreement with our simulations.
