Computing the forcing spectrum of outerplanar graphs in polynomial time

The forcing number of a graph with a perfect matching M is the minimum number of edges in M whose endpoints need to be deleted, such that the remaining graph only has a single perfect matching. This number is of great interest in theoretical chemistry, since it conveys information about the structur...
