Path assignment is a core issue for optical ring networks.On the basis of the characteristics of the Genetic Algorithm （GA）,Particle Swarm Optimization （PSO）algorithm and Ant Colony Algorithm （ACA）,this paper proposes a novel hybrid ACA algorithm incorporating PSO and ant GA and searches the optimal ring path in optical networks.Simulation results indi-cate that the proposed algorithm outperforms the basic ACA and the hybrid GA and PSO algorithm in terms of convergence speed and the search results,confirming its effectiveness.
