Breadth spanning tree

WebThus any spanning tree is a MST. When you use BFS or DFS to explore a graph, you build an exploration tree, which is the shortest path tree for BFS. And if the graph is unweighted, you can say this tree is a MST, yes so 1. … WebJun 15, 2024 · 1 Answer. If you're looking for all possible spanning trees, then you don't actually need to do a BFS. You can just set every edge's weight to 1, then run an algorithm that finds all minimum spanning trees in the graph. This works because all spanning trees have V-1 edges (where V represents the number of vertices).
