Overview
We discuss the minimum spanning problem in the context of undirected graphs. The same problem can be discussed for directed graphs but in that case it is referred to as the Optimal Branching Problem.
The Problem
Given an undirected graph G=(V, E) and a positive or negative cost ce for each edge e ∈ E, find the minimum cost spanning tree T ⊆ E (MST).
