Minimal Spanning Trees

Minimal Spanning Trees. What is a minimal spanning tree (MST) and how to find one. Tree. A tree contains a root, the top node. Each node has: One parent Any number of children. Spanning Tree. A spanning tree of a graph is a subgraph that contains all the vertices and is a tree (connected).
