Graph Algorithms

Graph Algorithms. Andreas Klappenecker [based on slides by Prof. Welch]. 1. Directed Graphs. Let V be a finite set and E a binary relation on V, that is, E ? VxV. Then the pair G=(V,E) is called a directed graph . The elements in V are called vertices .

SSSP in DAGs (directed acyclic graphs)

SSSP in DAGs (directed acyclic graphs). DFS (depth first search) DFS(vertex v) { v.visited = TRUE; for each w adjacent to v do if(!w.visited) then dfs(w); } If G=(V,E) not (strongly) connected then it may have DFS forest. Topological Sort.
