Abstract: |
In this paper, an improved immune genetic algorithm for solving optimal path of travelling salesman problem is introduced. Stochastic method and greedy method are combined to produce the initial chromosomes populations. Based on affiity sorting, antibodies are selected to gain replicated subguoup. Roulette and clone selection are introduced in sequence to get high affiity antibodies. Nextly, vaccination and immune memory operations are implemented to revamp antibody. Using immune memory mechanism, city array generated by the new algorithm is proved to be globally convergent. Numerical experiments prove that the new algorithm is valid. |
