N2 - In this paper, we consider the prize-collecting edge dominating set problem, which is a generalization of the edge dominating set problem. In the prize-collecting edge dominating set problem, we are not forced to dominate all edges, but we need to pay penalties for edges which are not dominated. It is known that this problem is script N P-hard, and Parekh presented a 8/3-approximation algorithm. To the best of our knowledge, no polynomial-time solvable case is known for this problem. In this paper, we show that the prize-collecting edge dominating set problem in trees can be solved in polynomial time.
