A new heuristic algorithm for the restricted Block Relocation Problem

ABSTRACT
We present a new lower bound and a heuristic approach for the restricted Block Relocation Problem. The proposed lower bound can becomputed in polynomial time and it is provably better than some previously known lowerbounds. We use it within a bounded beam search algorithm to solve BRP and show that the considered heuristic approach outperforms the other existing algorithms on most of the instances in the literature. New large instances, to test the approaches on real-size BPR problems, are also introduced.
