Abstract
The quadratic assignment problem (QAP) is one of the hardest combinatorial optimization problems.

Its range of applications is wide, including facility location, keyboard layout, and various other domains.
The key success factor of specialized branch-and-bound frameworks for minimizing QAPs is an efficient implementation of a strong lower bound.
In this talk, we propose a lower-bound preserving transformation of a QAP to a different quadratic problem allowing for small and efficiently solvable SDP relaxations. This transformation is self-tightening in a branch-and-bound process. Experimental evaluations show promising results, in particular for instances with a small width in one of the dimensions.
