Descripción:
A procedure for counting edge covers of simple graphs is presented. The procedure splits simple graphs into non-intersecting cycle graphs. This is a low exponential exact algorithm to count edge covers for simple graphs whose upper bound in the worst case is O (1.465575 ( m n ) × ( m + n )) , where m and n are the number of edges and nodes of the input graph, respectively.
