[PDF] 1 General approach for finding minimum spanning trees

Our two algorithms (Kruskal's and Prim's) both use a greedy strategy, where on each iter- ation we add one of the graph's edges to the minimum spanning tree

The minimum spanning tree in a weighted graph G(V,E) is one which has In light of this, the basic outline of our minimum spanning tree algorithms is going to be A more sophisticated data structure, the d-ary heap, performs even better
