- Att-GCN: I use the code from https://github.com/Spider-scnu/TSP/tree/master. All the environments and settings are the same as the author recommended.
- Farthest Insertion: I use the implemention in GLOP (https://github.com/henry-yeh/GLOP/blob/master/problems/tsp/tsp_baseline.py)
- raw-2opt: just import TSPModel from pl_tsp_puredecoding instead of pl_tsp_model_rddm in disco/train.py
