Genetic Algorithm(GA) is an effective search algorithm for the solution of combinatorial optimization problems. Based on the existing genetic algorithm in solving the TSP problem, an efficient hybrid genetic algorithm is proposed in this paper. A scheme that optimizes the initial population by the Tabu search and introduces the alien population for the diversity is applied in this algorithm. Numerical experiments using EIL51 data set in TSPLIB are carried out, which demonstrate that the scheme can not only ...
