B. J. van Kesteren,K. Tj. Bos at proving optimality, and the opposite heuristic for which the reverse is true. We suggest that in designing heuristics for optimization problems, the different requirements of the two tasks (finding an optimal solution and proving optimality) should be taken into account.

K. Bos,A. Ruijters,A. Visschere develop a time-table-edge-finding propagator for . that explains its propagations. We give results using this propagator in a lazy clause generation system on resource-constrained project scheduling problems from various standard benchmark suites. On the standard benchmark suite PSPLib, we are abl

The limitations of the MIP model and the critical aspects of the CP model are discussed. Symmetry breaking and parallel computing are also shown to bring significant benefits.

M. Beishuizen,E. Felix,J. J. Beishuizenes. These cuts are then added to the mixed integer linear program (MILP) during the search leading to a tighter linear relaxation of the MINLP. Results show large reductions of the optimality gap of a two step MILP-NLP solution method due to the tighter linear relaxation obtained.
