Scalable Self-Supervised Learning for Multiphase AC-OPF in Distribution Systems with Topology Reconfiguration

The Penalty + Sequential Linearized Feasibility Seeking (SLFS) algorithm is presented, a self-supervised learning framework for multiphase distribution AC-OPF under switch-induced topology changes, demonstrating a viable path toward real-time, topology-aware AC-OPF for large-scale distribution grids.

Learning Discrete Decisions for MIPs with Constraint-Aware Diffusion

Constrained Graph Diffusion, a graph-based generative diffusion model that learns the discrete component of mixed-integer optimization problems while integrating a training-free feasibility projection operator directly into the reverse diffusion process to steer intermediate samples toward the feasible set throughout generation, is proposed.
