Abstract: It can restrain premature of ant colony algorithms and accelerate the convergence rate of the algorithms, combining ant colony algorithms with heuristic algorithms. The solution quality and efficiency of heuristic algorithms can be improved through establishing reference optimization edge set used by local search algorithms. The strategy of path exchanging can improve convergence rate and capacity of searching optimal solution. The results of experiments indicate that new hybrid ant colony algorithm can find global optimal solution of TSP whose scale is less than 2000.
