A Geometric Perspective on the Difficulties of Learning GNN-based SAT Solvers

Researchers explain why Graph Neural Networks (GNNs) struggle with complex Boolean Satisfiability Problems (SATs) through geometric analysis using graph Ricci Curvature. They prove that harder SAT instances have more negative curvature, creating connectivity bottlenecks that prevent GNNs from effectively processing long-range dependencies.

RAwR: Role-Aware Rewiring via Approximate Equitable Partition

Researchers introduce RAwR, a graph neural network rewiring framework that addresses the oversquashing problem by augmenting graphs with quotient graphs derived from equitable partitions. The method improves GNN performance on long-range prediction tasks while maintaining computational efficiency and demonstrates state-of-the-art results across diverse benchmarks.
