Finally, we provide some background for more recent work that uses matroids, speci cally that of nding a uniform spanning tree of a graph. ridgeback guinea pigsFor a graph with E edges and V vertices, Kruskal's algorithm can be shown to run in O(E log E) time, or equivalently, O(E log V) time, all with simple data structures. These running times are equivalent because: • E is at most and . • Each isolated vertex is a separate component of the minimum spanning forest. If we ignore isolated vertices we obtain V ≤ 2E, so log V is . ridgeback harmony
