给定无向赋权图G和直径约束值D,直径约束最小生成树问题是查找一个直径不超过D最小权重的生成树.当时,其是NP-hard问题.用蚁群算法对其进行求解,设计了一种新的当前节点选择规则.分析和实验表明,基于新的节点选择规则的蚁群算法对直径约束最小生成树问题有较好的求解效果.
給定無嚮賦權圖G和直徑約束值D,直徑約束最小生成樹問題是查找一箇直徑不超過D最小權重的生成樹.噹時,其是NP-hard問題.用蟻群算法對其進行求解,設計瞭一種新的噹前節點選擇規則.分析和實驗錶明,基于新的節點選擇規則的蟻群算法對直徑約束最小生成樹問題有較好的求解效果.

Given a connected, weighted, undirected Rraph G and a bound D, The bounded diameter minimum spanningtree problem sought a spanning tree on G of mintmurn weight among the trees in which no path between two -vertices contains more than D edges. This problem was NP-hard for 4≤D ≤│V│-1. Ant colony algorithm was designed for the bounded diameter minimum spanning tree problem, which based on new node-selection strategy. The algorithm was proved to be effective by analysis and experiments..
