# Preprint reports GPU guidance improves CPU constraint-solving results

Researchers report that a hybrid GPU-CPU framework improved solution scores for Weighted Partial MaxSAT, a problem that requires satisfying mandatory constraints while maximizing the value of optional ones. In a preprint, they tested all 229 instances of the MSE 2024 anytime weighted benchmark against its top two winners.

At a 300-second limit, average scores improved by up to 4.9% over tt-open-wbo-inc-Glucose and 4.8% over SPB-MaxSAT-c-FPS. The GPU optimizes candidate variable assignments without training data or a pretrained model, then supplies guidance to CPU solvers.

The method prioritizes mandatory constraints before weighted objectives. The reported gains concern this benchmark and time limit.
