Mayeda and Ramamoorthy have reduced the problem of finding a minimum number of test points which detect an improperly operating functional element of a single entry-single exit (SEC) system graph, to the problem of finding a minimum number of edges under which this system graph is 1 distinguishable. This correspondence shows that the determilnation of the minimum edge set is equivalent to the determination of a minimum covering of a certain matrix M (S) of zeros and ones. A way of finding the matrix M (S) is proposed.
Directed graphs, fault location, minimum coverng, minimum number of test points, one distinguishability.
