PPT-Shortest Path

Prims Djikstras PRIMs Minimum Spanning Tree A spanning tree of a graph is a tree that has all the vertices of the graph connected by some edges A graph can have one or more number of spanning trees. . Shortest Paths. CSE 680. Prof. Roger Crawfis. Shortest Path. Given a weighted directed graph, one common problem is finding the shortest path between two given vertices. Recall that in a weighted graph, the .
