The problem originally stated in algebraic terms is translated, introducing the so called Kunz-coordinates, to resolve a series of several discrete optimization problems. First, we prove that finding a minimal m-irreducible decomposition is equivalent to solve a multiobjective linear integer problem. Then, we restate that problem as the problem of finding all the optimal solutions of a finite number of single objective integer linear problems plus a set covering problem. Finally, we prove that there is a suitable transformation that reduces the original problem to find an optimal solution of a compact integer linear problem. This result ensures a polynomial time algorithm for each given multiplicity m. We have implemented the different algorithms and have performed some computational experiments to show the efficiency of our methodology.", "revisions": [ { "version": "v1", "updated": "2011-01-21T11:30:44.000Z" } ], "analyses": { "subjects": [ "90C10", "20M14", "11D75" ], "keywords": [ "numerical semigroup", "integer programming", "compact integer linear problem", "optimal solution", "objective integer linear problems plus" ], "note": { "typesetting": "TeX", "pages": 22, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2011arXiv1101.4112B" } } }
