Table 2.1. Adjacency matrix for Figure 2.3. (c). A 1 2 3 4 0 100 200 50 1 2 0 75 3 0 4 45 85 0 2.3. Warshall's Algorithm Warshall's algorithm the shortest path between every pair of vertices in digraph using Boolean operators and matrices. Begin by creating an adjacency matrix A for Figure 6. As before, with one notable difference instead of using weights (and you will have noticed by now that none are assigned to digraph in figure below), we use Boolean operators. That is to say, if there is a path, enter a 1 in matrix A, and enter 0 if no path exists (Lu, Hongjun et al., 1987), as shown ‏ in Table 2.2.
