"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×.
