For the Hopfield network in solving the traveling salesman problem offen getting unvalid and not optimal solution, this paper introduced a suitable radom initialization of the output values Vxi of permutation matrix to guarantee an effective solution, used the error produced by taking a larger step size and required new solution to be better than or equal to old solution so that the final result can jump out local minima to find the global optimal solution.

摘 要：针对Hopfield网络解旅行商问题经常出现无效解和局部优化解，本文给出置换矩阵的满足一定条件的元素Vxi作为初始值，以便得到有效解。此外，还利用较大的步长所产生的误差和对当前解必须优于或等于已有解的要求，使计算结果能从局部优化解达到全局最优解。
