【摘要】 旅行商问题是一个NP-Hard组合优化问题。根据蚁群优化算法和旅行商问题的特点,论文提出了对蚁群中具有优质解的蚂蚁个体所走路径上的信息素强度进行增强的方法,并同其他的优化算法进行了比较,仿真结果表明,对具有全局和局部最优解的个体所走路径上的信息素强度进行增强的蚁群优化算法比标准的蚁群优化算法和其他优化算法在执行效率和稳定性上要高。更多还原

【Abstract】 Traveling Salesman Problem(TSP)is a NP-Hard combinatorial optimization problem.According to the merits of Ant Colony Optimization(ACO)and the characters of TSP,methods are proposed to make ACO run efficiently by modi-fying and strengthening the pheromone intensity of the ants with the best solutions in the current or global ant colonies,and are compared with other evolutionary algorithms such as Genetic algorithm,Simulated Annealing.The experi-ment results prove that the improved ACOs are more efficient than the standard ACO and superior to other evolution-ary algorithms.Moreover,the results suggest that these improved ACOs may find wide applications in the combinatorial optimization filed in the future.更多还原
