    Quantum-Cooperative Method for Maximum Weight Perfect Matching Problem of Bipartite Graph

    • 摘要: 信息科学中许多组合优化问题可抽象为二分图最大权完美匹配问题.由于数据量的增长,经典算法难以平衡匹配问题求解效率和求解精度的矛盾.基于此,提出一种适用于求解通用最大权完美匹配的智能优化方法.该方法将原始的矩阵形式的匹配候选解转换成可被智能优化算法处理的演化基结构,通过子代选择和量子策略协同过程,自适应地从改进的离散粒子群策略以及模拟退火策略中选择适用于当前演化过程的有效策略,并在保持种群稳定进化的同时促使种群快速收敛.通过不同类型检验函数以及不同维度匹配矩阵的实验,结果表明:与其他方法相比,该方法在有限迭代次数内具有较高的收敛精度以及较快的收敛速度,体现出对经典问题以及高维匹配问题的适应能力.

       

      Abstract: Most combinational optimization problems of information science can be abstracted into the maximum weight perfect matching problem of bipartite graph. Due to the growth in the amount of data, classical algorithms of solving the matching problem of bipartite graph are difficult to balance the contradiction between the efficiency of the algorithms and the precision of the solutions. Based on this point, an intelligent optimization method to solve the general maximum weight perfect matching problem is proposed. The method converts the matrix form of an original candidate matching solution into the evolution basis which the intelligent algorithm can handle, and adaptively chooses the effectively evolutionary strategies from the improved discrete particle swarm optimization and simulated annealing based on the off-spring selection and the quantum-cooperative process, and moreover, it maintains the steady evolution and promots the rapid convergence of the population. According to the experimental results of the test functions with the various types and the matching matrixes with the various dimensions, the proposed method outperforms other algorithms under the condition of the restricted iteration, and presents the higher convergence precision and the faster convergence speed, as well as the adaptability to various kinds of the classical optimization problems and the high dimensional matching problems.
