For a complete … WebSep 13, 2024 · Classic BFS performs work proportional to V2 and E-BFS performs work proportional to V, so the ratio of runtimes increases in proportion to V. For a complete graph with 2,000 vertices (and thus 1,999,000 edges), E-BFS is more than 9,400 times faster than classic BFS. For V =10,000 (and thus E = 49,995,000), E-BFS wins by nearly 73,000×.

WebNext we have a similar graph, though this time it is undirected. Figure 2 gives the pictorial view. Self loops are not allowed in undirected graphs. This graph is the undirected version of the the previous graph (minus the parallel edge (b,y)), meaning it has the same vertices and the same edges with their directions removed.Also the self edge has been removed, … WebThe breadth_first_search () function performs a breadth-first traversal [ 49] of a directed or undirected graph.
