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.
