Artificial glowworm swarm optimization(AGSO) algorithm is proposed as a new bionic swarm of intelligent algorithm, which is successfully applied to complicated function optimization, and shows good performance. In order to give full play to the advantages of glowworm swarm optimization, the proposed algorithm is combined with C2Opt operator, and a new efficient AGSO algorithm about travelling salesman problem(TSP) is designed. The numerical experiment results show that the proposed algorithm can find the global optimal solution with less computation and evolving time.
