1、求解多目标最小生成树的改进多目标蚁群算法高晓波【期刊名称】计算机应用研究【年(卷),期】2011(028)002【摘要】 多目标最小生成树问题是典型的 NP 问题 .针对此问题 ,提出一种改进的 多目标蚁群算法 .为获得更好的非劣前端 ,通过合理选取多个信息素扩散源与扩散 策略来避免其早熟收敛 ,并引入非支配排序算子 ,提高种群多样性并避免算法过早 陷入局部最优解 .对比实验结果表明 :对于多目标最小生成树问题 ,该算法是有效 的 ,不但在求解效率和解的质量方面优于相关算法,而且随着问题规模的扩大 ,算法仍保持较好的性能 .%Multi-objective minimum spanning t
2、ree problem is a typical NP problem.For this problem, this paper proposed an improved ant colony algorithm for multi-objective, non-inferiority in order to obtain a better front end, by choosing the number of pheromone diffusion source and diffusion strategy avoid premature convergence.And the intro
3、duction of mutation operator was to enhance population diversity and avoid falling into local optimal solution algorithm prematurely.Comparison of experimental results shows that for multi-objective minimum spanning tree problem, the algorithm is effective not only in the solution efficiency of the quality of reconciliation is better than related algorithms.With the expansion of scale of the problem and algorithm remains a good performance.总页数】 3 页(474-476)
