Abstract

Permutation matrices resulting from triangular factorization of shifted symmetric matrices with pivoting are used as initial approximations for a series of elementary permutations improving the objective function value in the quadratic assignment problem. The proposed method is tested on 128 test problems from QAPLIB.
