http://www.duoduokou.com/algorithm/40884424276240696316.html WebWarshall's algorithm is used to determine the transitive closure of a directed graph or all paths in a directed graph by using the adjacency matrix. For this, it generates a sequence of n matrices. Where, n is used to describe the number of vertices. A sequence of vertices is used to define a path in a simple graph.

WebUnlike the single-source algorithms, which assume an adjacency list representation of the graph, most of the algorithm uses an adjacency matrix representation.
