In this paper we consider the two dimensional strip packing problem with guillotine cuts. The problem consists on packing a set of rectangular items on one strip of width W and infinite height. The items packed without overlapping, must be extracted by a series of cuts that go from one edge to the opposite edge (guillotine constraint). For this problem, we give a new lower bound based on decomposing the set of the items in sub-sets. This lower bound is used in a branch and bound algorithm to solve the problem to optimality. Computational results are presented to show the performance of both the lower bound and the exact algorithm
