Warshall’s Algorithm C Program

C Program To Implement Warshall’s Algorithm To Find Path Matrix

Learn how to Implement Warshall’s Algorithm to find path matrix in C programming. Alternatively, we can find path matrix of any graph by using powers of an Adjacency Matrix. However, Warshall’s Algorithm provides an efficient technique for finding path matrix of a graph.

The Warshall Algorithm is also known as Floyd – Warshall Algorithm, Roy – Warshall, Roy – Floyd or WFI Algorithm. It is a type of Dynamic Programming. It is basically used to find shortest paths in a weighted graph with non – zero edge weights. The Warshall algorithm is an efficient algorithm to compute compute paths between all pairs of vertices in dense graphs.

    Can you enlist other algorithms to find Path matrix?

    • August 26, 2016 at 4:47 pm

      Yes. Ofcourse. Here is the list of some of the frequently used algorithms to compute the path matrix. There could be many more algorithms apart from these.

      • Djikstra’s Algorithm
      • Bellman Ford Algorithm
      • Johnson’s Algorithm
      • A* Search Algorithm

    Dijkstra’s algorithm is much better than warshall’s algorithm to find path matrix.

    P[i][j] = (P[i][j] || (P[i][k] && P[k][j]));
    what does this do can you please explain??
