The bipartite travelling salesman problem: A pyramidally solvable case
Vladimir G. Deineko, Bettina Klinz, Gerhard J. Woeginger
In the bipartite travelling salesman problem (BTSP), we are given cities along with an distance matrix and a partition of the cities into red and blue ci…
New special cases of the Quadratic Assignment Problem with diagonally structured coefficient matrices
Eranda Cela, Vladimir Deineko, Gerhard J. Woeginger
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 sp…
Linearizable special cases of the QAP
Eranda Cela, Vladimir G. Deineko, Gerhard J. Woeginger
We consider special cases of the quadratic assignment problem (QAP) that are linearizable in the sense of Bookhold. We provide combinatorial characterizations of the linearizable i…
Geometric versions of the 3-dimensional assignment problem under general norms
Ante Ćustić, Bettina Klinz, Gerhard J. Woeginger
We discuss the computational complexity of special cases of the 3-dimensional (axial) assignment problem where the elements are points in a Cartesian space and where the cost coeff…
Planar 3-dimensional assignment problems with Monge-like cost arrays
Ante Ćustić, Bettina Klinz, Gerhard J. Woeginger
Given an cost array we consider the problem -P3AP which consists in finding pairwise disjoint permutations of s…
Well-solvable cases of the QAP with block-structured matrices
Eranda Çela, Vladimir G. Deineko, Gerhard J. Woeginger
We investigate special cases of the quadratic assignment problem (QAP) where one of the two underlying matrices carries a simple block structure. For the special case where the sec…
