TSP More on Att-GCRN

Hi @Spider-scnu, thank you for the super insightful work and for releasing the code!

I had a quick question re. the GNN model used 'Att-GCRN'. Is this model any different from the model proposed in Joshi-etal, 2019? On looking at the code, it seems the same overall architecture.

Hi, the code of backbone Att-GCRN is baed on Joshi-etal, 2019, and also I have add training tricks and done some modification about the implementation of attention. In our paper, we stressed the importance of sampling techniques and our MCTS improvement methods to solve the big TSP instances.
