Kruskal's Algorithm

MST Problem:

Given a connected graph G=(V,E) and a weight d:E->R+, find a minimum spanning tree T.

Kruskal's Algorithm

  1. Set i=1 and let E0={}
  2. Select an edge ei of minimum value not in Ei-1 such that Ti=<Ei-1 cup {ei} >is acyclic and define Ei=Ei-1 cup {ei}. If no such edge exists, Let T=<Ei>and stop.
  3. Replace i by i+1. Return to Step 2.
