Equality of complexity classes P and NP: Linear programming formulation of the quadratic assignment problem
arXiv:cs/0609004
Abstract
In this paper, we present a polynomial-sized linear programming formulation of the Quadratic Assignment Problem (QAP). The proposed linear program is a network flow-based model. Hence, it provides for the solution of the QAP in polynomial time. Computational testing and results are discussed.
