摘要
提出了度、直径约束最小生成树问题,证明了该问题是NP-完全的.建立了该问题的数学规划模型.给出了启发式求解算法,其时间复杂性为O(mn).分析和实例实验表明,该算法有良好的效果.
The degree -constrained and diameter- constrained minimum spanning tree problem was discussed, which proved to be NP- Complete. A mathematical programming model of the problem was proposed. A heuristic algorithm was proposed to solve this problem, whose time complexity was 0 (mn). The algorithm was proved to be effective through analysis and experiments.
