【Abstract】 Backtracking algorithm is one of the efficient methods to solve N-queens problem. Based on the solving N-queens problem by using backtracking algorithm, the thinking of the dynamic programming was introduced to improve the algorithm, and the complexity of the solution and comparative number was greatly reduced. At the same time, the concrete realization of the improved Non-recursive algorithm was implemented and the feasibility of this algorithm was proved through theoretical analysis and experimental data in the paper.更多还原
