最小生成树——Minimum Spanning Tree,是图论中比较重要的模型,通常用于解决实际生活中的路径代价最小一类的问题。我们首先用通俗的语言解释它的定义: 对于有n个节点的有权无向连通图,寻找n-1条边,恰好将这n个节点相连,并且这n-1条边的权值之和最小。 对于MST问题,通常常见的解法有两种:Prim算法或者Kruskal算法...

图的定义时 我们规定一个连通图的生成树是一个极小连通子图 含有N个顶点N-1个边 我们把图中带权的边 最小代价生成的树成为最小生成树。 普里姆(Prim)算法 prim算法适合稠密图,其时间复杂度为O(n^2),其时间复杂度与边得数目无关以顶点找顶点 考虑权值 存储方式为邻接矩阵 基本思想:假设G=(...
Prim’s Algorithm also use Greedy approach to find the minimum spanning tree. In Prim’s Algorithm we grow the spanning tree from a starting position. Unlike an edge in Kruskal's, we add vertex to the growing spanning tree in Prim's. Algorithm Steps: Maintain two disjoint sets of verti...
3. Repeat step 2 (until all vertices are in the tree). Let’s say we have a graph Here is step by step execution of Prim’s algorithm (note that for steps where we have multiple same minimum weight options, I am choosing randomly)...
最小生成树(Minimum Spanning Tree)是一个在连通加权图中的生成树中,边的权值之和最小的生成树。Prim算法是解决最小生成树问题的经典算法之一,基本思想是从一个初始顶点开始,逐步将与当前树相连的边中权值最小的边加入生成树中,直到所有顶点都被包含在生成树中为止。具体实现时,可以使用优先队列来维护当前候选边...

the storage of edges in minimum cost spanning tree(for short, MCST) has been realized by the vertex array ,which is created by the special data structure. Through the vertex array, the vertices in V-U set constitute a static bi-directional circular linked list, so Prim algorithm realizes ...
