Claims

C1strongest claim

We present DQI-Kit, a software framework that provides a unified, extensible interface for automatically encoding constrained optimisation problems into Max-LINSAT. Users can describe the various types of objectives and constraints that are common in industrial optimisation problems. Our framework converts these into Max-LINSAT instances via a series of problem transformations and computes an estimate of the expected performance of DQI on these instances.

C2weakest assumption

The transformations implemented in DQI-Kit will produce Max-LINSAT instances whose DQI performance estimates meaningfully reflect the overheads and potential advantage of the original constrained problem.

C3one line summary

DQI-Kit automates encoding of objectives and constraints into Max-LINSAT instances and estimates expected DQI performance on the resulting problems.
