具有对角结构系数矩阵的二次指派问题的新特例

New special cases of the Quadratic Assignment Problem with diagonally structured coefficient matrices

Eranda Cela, Vladimir Deineko, Gerhard J. Woeginger

摘要:

我们考虑新的多项式可解的情况下,著名的二次指派问题涉及系数矩阵具有特殊的对角结构。通过将新的特殊情况与文献中已知的多项式可解的特殊情况相结合,我们得到了一类新的更大的多项式可解的QAP特殊情况,其中所涉及的两个系数矩阵之一是具有附加结构性质的Robinson矩阵:该矩阵可以表示为截矩阵的圆锥组合。另一个矩阵是单调反蒙格矩阵和向下仁慈的Toeplitz矩阵的圆锥组合。我们考虑的识别问题的特殊类的罗宾逊矩阵上述,并表明,它可以在多项式时间内解决。

英文摘要:

We consider new polynomially solvable cases of the well-known Quadratic Assignment Problem involving coefficient matrices with a special diagonal structure. By combining the new special cases with polynomially solvable special cases known in the literature we obtain a new and larger class of polynomially solvable special cases of the QAP where one of the two coefficient matrices involved is a Robinson matrix with an additional structural property: this matrix can be represented as a conic combination of cut matrices in a certain normal form. The other matrix is a conic combination of a monotone anti-Monge matrix and a down-benevolent Toeplitz matrix. We consider the recognition problem for the special class of Robinson matrices mentioned above and show that it can be solved in polynomial time.
