dc.description.abstractEn | Primal heuristics have become an essential component in mixed integer programming (MIP). Generic heuristic paradigms of the literature remain to be extended to the context of a column generation so- lution approach. As the Dantzig-Wolfe reformulation is typically tighter than the original compact formulation, techniques based on rounding its linear programming solution have better chance to yield good primal so- lutions. However, the dynamic generation of variables requires specific adaptation of heuristic paradigms. We focus here on "feasibility pump" approaches. We show how such methods can be implemented in a context of dynamically defined variables, and we report on numerically testing "feasibility pump" for cutting stock and generalized assignment prob- lems. | |
