Apr 06, A Minimum Spanning Tree(MST) or minimum weight spanning tree for a weighted, connected, undirected graph is a spanning tree having a weight less than or equal to the weight of every other possible spanning tree. The weight of a spanning tree is the sum of weights given to each edge of the spanning tree. A minimum weight edge in an undirected graph belongs to some minimum spanning tree.

The inverse of the Theorem about safe edges is not true. In other words, if (u,v) is a safe edge for A crossing (S, V−S) then it is not necessarily a light edge. Consider the set: {(u,v): there exists a cut (S, V−S) such that (u,v) is a light edge crossing it}.

### Spanning tree with exactly k orange edges.

Specifically, a cut set is said to be a minimal cut set if, when any basic event is removed from the set, the remaining events collectively are no longer a cut set. Minimal cut sets have traditionally been used to obtain an estimate of reliability for complex reliability block diagrams (RBDs) or fault trees that can not be simplified by a combination of the simple constructs (parallel, series, k-out-of-n).
