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.
