The last graph of the example to the Reverse-delete algorithm still contains a cycle (A,B,E,F,D), therefore the algorithm will in the next (and last) step check the next largest edge EF and delete it.
After reading Kruskal's 1956 paper "On the shortest spanning subtree of a graph and the traveling salesman problem", I think that his Construction A' is exactly the reverse-delete algorithm. Why is this not cited? Did someone else create it? AustinBuchanan (talk) 04:31, 29 May 2013 (UTC)[reply]
