Power system transient stability assessment via physics-informed graph convolutional networks

Transient Stability Assessment is the first line of defense for the safe and stable operation of power grids, which is decisive for ensuring the continuity of power supply and reducing system operational risks. Addressing the challenges that traditional time-domain simulation methods have low computational efficiency a...

SHSP: Structure-Aware Hierarchical Solution Prediction for Mixed-Integer Linear Programming

The Structure-Aware Hierarchical Solution Prediction (SHSP) framework is proposed that replaces the parallel marginal decoding of one-shot methods with a novel hierarchical conditional decoding mechanism and significantly outperforms existing one-shot prediction baselines.

Learning Early-to-Final Solution Consistency for MILP Acceleration

This paper finds that solutions produced at the early search stage of MILP solvers are often structurally close to the solutions found after full-budget search, and proposes a new solver-informed paradigm that shifts the learning target from variable assignment to early-to-final consistency.
