The Steiner tree problem has been determined to be an NP-complete problem. There are a number of approximation algorithms for the Steiner tree problem. In this section, we discuss a well-known approximation algorithm developed by Kou, Markowsky, and Berman in 1981 [461], which we will refer...
Manhattan空间有障碍的最短路径和3_Steiner树算法
Display full size Figure 2We utilized the Steiner minimal tree algorithm to construct a specific network for osteoarthritis (OA) from the human interactome network. This algorithm effectively connected the maximal and minimal members of gene nodes. The resulting OA network consisted of 182 nodes and...
Finally, an analysis of the algorithm. Key words: steiner minimum tree; NP-hard problem; loop damage method 现实生活中经常要求解决这样的问题 ,即将假设干给定点相连并使连线的总长最短。即最小生成树问题 (Minimum Spanning Tree— MST)。最小生成树问题是运筹学、 组合优化中的常见问题 ,即寻找一棵...
另一个改进的方法是Hadlock于1977年提出的,称为Hadlock最小迂回方法([Hadlock,A Shortest Path Algorithm forGrid Graphs,Networks,1977.7,323-334.])。上述两种改进的迷宫方法的时间与空间复杂度均为0(hw),其中h和w是网格的数目。迷宫方法的最大缺点是要搜索较大的布图空间,所以要花费较大的时间和存储空间。它...
