CVRPLIB inference problem

[Elon-Lau]

Can you give an example for how to use pre-trained model to solve instances in CVRPLIB?

[LOGOLAB-CUHKSZ]

Hello Elon,
Thanks for reaching out! You can use the Python library provided at https://github.com/PyVRP/VRPLIB to read CVRPLib instances. What's more, we recommend to do the evaluation in the corresponding source codes by loading the pretrained parameters obtained from ASP.
Feel free to contact us if you have further questions!

Best,

Do you have a ssh command that you can run directly? Do I need to modify the source code of the eval function?

[LOGOLAB-CUHKSZ]

For a fair comparion, we highly recommend conducting the evaluation using the source code of the respective works.
For example, if you are using POMO, you need to modify the load_problems function found at the following link:
https://github.com/yd-kwon/POMO/blob/d7c3d6ea580499a53e874fe9e065f69e799a8551/NEW_py_ver/CVRP/POMO/CVRPEnv.py#L95
to read the cvrplib instances. Then you can load the pretrained model to perform the evaluation.
