Let G = (V,E) be a weighted, directed graph with a source vertex s E V that has been initialized by INITIALIZE-SINGLE-SOURCE(G,s). Prove that if a sequence of relaxation steps sets s.? to a non-nil value, then G contains a negative-weight cycle. Can you rely on this method to detect negative-weight cycles in a graph?
