Abstract: Usually, there are many zero elements in the flow matrix and distance matrix of the quadratic assignment problem (QAP) instances abstracted from the practical problems, and the computation time of solving this kind of QAP can be dramatically decreased by using its zero elements to reduce the size of the problem. Based on the linearization of the QAP, we proposed a new solution method for the QAP with many zero elements in both flow matrix and distance matrix in this paper. Moreover, the feasibilities and advantages of solving this special kind of QAP by using the new linearization are approved from the theoretical and experimental point of view, respectively.
