WebQuestion: Let G be a directed graph whose edges have weights. Some edge weights are negative but G does not have a negative cycle (i.e., the total weight of the edges of any cycle of G is nonnegative). Let s and t be two vertices of G. Suppose we want to find a shortest path from s tot in G. WebAll edges in a graph must be either WEIGHTED or UNWEIGHTED. In the first example graph, the directed edge from A to B has a weight of 5. The edge from B to C has …

Web3 nov. 2014 · Let’s start with a quick refresh on directed graphs and Dijkstra’s algorithm. G = (V, E) V - set of vertices; E - set of edges. Weighed directed graph also called weighed digraph is a graph containing a set of vertices (or nodes) connected by edges, where edges contain information about connection direction and the weight of that connection. WebIf your graph is unweighted, or equivalently, all edges have the same weight, then any spanning tree is a minimum spanning tree. As you observed, you can use a BFS (or even DFS) to find such a tree in time linear in the number of edges.
