We observe that data-driven models based on Graph Neural Networks offer intriguingly good performance, even in regimes where standard relaxation based techniques appear to suffer.

Quadratic graphs A quadratic graph is produced when you have an equation of the form y = a x 2 + b x + c, where b and c can be zero but a cannot be zero. All quadratic graphs have a line of symmetry.

The Quadratic assignment problem (QAP), referring to finding an optimal assignment between two sets of interrelated objects, is a fundamental problem in combinatorial optimization. It is widely ...
