A polynomial multicommodity flow problem with difficult path generation
(2011) 3rd International Workshop on Reliable Networks Design and Modeling (RNDM 2011) In 3rd International Congress on Ultra Modern Telecommunications and Control Systems and Workshops (ICUMT), 2011 Abstract
 In the paper we consider a commonly known network design problem with demand restoration assuming stub release. No compact linear programming (LP) formulation for the problem is known, and all known noncompact LP formulations of the problem require NPhard path generation (pricing). Therefore, the problem itself is suspected to be NPhard  this, however, is not actually known. The main result of our paper reveals a special case of the basic problem for which the resulting noncompact LP formulation still has an NPhard pricing problem, the corresponding compact LP formulation is not known either, but the problem itself is polynomial. The considered special case assumes only one failing link so that all the links but one are assumed to be... (More)
 In the paper we consider a commonly known network design problem with demand restoration assuming stub release. No compact linear programming (LP) formulation for the problem is known, and all known noncompact LP formulations of the problem require NPhard path generation (pricing). Therefore, the problem itself is suspected to be NPhard  this, however, is not actually known. The main result of our paper reveals a special case of the basic problem for which the resulting noncompact LP formulation still has an NPhard pricing problem, the corresponding compact LP formulation is not known either, but the problem itself is polynomial. The considered special case assumes only one failing link so that all the links but one are assumed to be 100% reliable. The constructed case of a polynomial multicommodity flow problem with difficult path generation is of interest since no such problem is, to the best of our knowledge, widely known. (Less)
