每对节点间最短路径 Floyd-Warshall 算法 D[i,j]表示从i到j的最短距离； P[i,j]表示从i到j的最短路径上j 的父节点-between each pair of nodes Shortest Path Floyd-Warshall algorithm D [i, j] said from i to j is the shortest distance; P [i, j] said from i to j the shortest path

有时仅对赋权有向图上从任意一个顶点到另外任意一个顶点之间有没有路感兴趣。试修改Floyd算法，计算出图的道路矩阵P，使得从顶点i到顶点j有路时P[i,j]= 1,否则P[i,j]= 0。-sometimes only to empower a map from any one vertex to another arbitrary point between a road not interested. Try to amend Floyd algorithm calculated the ro

folyd用来处理图论中最短路径问题。对传统的folyd算法进行了优化。-folyd to deal with the shortest path in graph theory problem. Folyd the traditional optimization algorithm.
