Floyd warshall algorithm คือ

The Floyd–Warshall algorithm can be used to solve the following problems, among others: • Shortest paths in directed graphs (Floyd's algorithm). • Transitive closure of directed graphs (Warshall's algorithm). In Warshall's original formulation of the algorithm, the graph is unweighted and represented by a Boolean adjacency matrix. Then the addition operation is replaced by logical conjunction (AND) and the minimum operation by logical disjunction (OR). WebThe Floyd-Warshall algorithm is a shortest path algorithm for graphs. Like the Bellman-Ford algorithm or the Dijkstra's algorithm, it computes the shortest path in a graph. However, Bellman-Ford and Dijkstra are both …
