WebSay, the node is u, now traverse each node in the adjacency list of u. Say, the node is v (i.e. u -> v) . In the transpose graph, add u to adjacency list of v (there exists and edge from v to u i.e. v -> u). Repeat this process for all the nodes (& their respective adjacency lists) in the graph until the transposed graph has been obtained. WebFeb 19, 2016 · Overall you could use more descriptive names in this function. I'd probably write it something like this: def adj_mtx (self): count = len (self.nodes) matrix = [ [0]*count for _ in range (count)] for src, dest in self.edge_list: src -= 1 dest -= 1 matrix [src] [dest] = 1 return matrix.

WebJul 15, 2015 · 2 Answers. An O (V* (V+E)) solution could be to do a simple BFS from every node in the graph and calculate its reachability set. Assuming E << V ^2 (you said the graph is sparsed), this is significantly faster (and simpler to code) than floyd-warshall. Your graph is a DAG, so you can first do a topological sort in O (V+E), then, go from last ... WebProof: The proof is by induction on k. For the base case, k = 1. By deﬁnition G1 = G, and A1 = A is the adjacency matrix for G. Now assume that Ak 1 is the adjacency matrix for Gk 1, and prove that Ak is the adjacency matrix for Gk.Since Ak 1 is the adjacency matrix for Gk 1, (Ak 1) i;j is 1 if and only if there is a walk in graph G of length k 1 from vertex i …
