Collaboration! Towards Robust Neural Methods for Routing Problems

Paper    Paper    License    Paper

The PyTorch Implementation of NeurIPS 2024 -- Collaboration! Towards Robust Neural Methods for Routing Problems. This paper improves the robustness of neural VRP solvers through adversarial training, which can also be viewed as enhancing their OOD generalization from the perspective of adversarial robustness (see ICLR'22).

Overview

Dependencies

  • Python >= 3.8
  • Pytorch >= 1.12

How to Run

# Example: POMO/TSP
nohup python -u train.py 2>&1 &
trainer_params["method"] = "ours"  # CNF (3)
trainer_params["method"] = "baseline"  # POMO_AT (3)
trainer_params["method"] = "baseline_hac"  # POMO_HAC (3)
