Researchers have developed WARP, a new benchmark and model for optimizing power grid operations. Previous machine learning approaches for predicting warm-start iterates for interior-point solvers were found to be ineffective due to an inappropriate baseline comparison. The new WARP model, an encode-process-decode interaction network, predicts the complete primal-dual state, achieving an 85% reduction in solver iterations and accommodating network topology changes without retraining.
