Generalizable Heuristic Generation Through LLMs with Meta-Optimization

ICLR 2026poster

Heuristic design with large language models (LLMs) has emerged as a promising approach for tackling combinatorial optimization problems (COPs). However, existing approaches often rely on manually predefined evolutionary computation (EC) heuristic-optimizers and single-task training schemes, which ma…

Towards Efficient Constraint Handling in Neural Solvers for Routing Problems

ICLR 2026poster

Neural solvers have achieved impressive progress in addressing simple routing problems, particularly excelling in computational efficiency. However, their advantages under complex constraints remain nascent, for which current constraint-handling schemes via feasibility masking or implicit feasibilit…

Learning to Handle Complex Constraints for Vehicle Routing Problems

NeurIPS 2024poster

Vehicle Routing Problems (VRPs) can model many real-world scenarios and often involve complex constraints. While recent neural methods excel in constructing solutions based on feasibility masking, they struggle with handling complex constraints, especially when obtaining the masking itself is NP-har…

Learning Generalizable Models for Vehicle Routing Problems via Knowledge Distillation

NeurIPS 2022accept

Recent neural methods for vehicle routing problems always train and test the deep models on the same instance distribution (i.e., uniform). To tackle the consequent cross-distribution generalization concerns, we bring the knowledge distillation to this field and propose an Adaptive Multi-Distributio…
