The Quadratic Assignment Problem (QAP) is a discrete optimization problem which can be found in economics, operations research, and engineering. It seeks to locate N facilities among N fixed locations in the most economical way. This paper gives a brief introduction to QAP and discusses how to reduce the problem size to N-1 if the original problem satisfies certain conditions.
