It follows that there is no duality gap for a pair of tropical primal-dual problems. This result together with known properties of subeigenvectors enables us to directly solve a special tropical linear program with two-sided constraints. We also study the duality gap in tropical integer linear programming. A direct solution is available for the primal problem. An algorithm of quadratic complexity is presented for the dual problem. A direct solution is available provided that all coefficients of the objective function are integer. This solution yields a good estimate of the optimal objective function value in the general case.", "revisions": [ { "version": "v1", "updated": "2017-09-26T12:51:51.000Z" } ], "analyses": { "subjects": [ "15A18", "15A80" ], "keywords": [ "integer programs", "duality gap", "direct solution", "simple compact proofs", "special tropical linear program" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable" } } }
