Hi! Thanks for your compliments. I'm not sure what you mean exactly, if you refer to split delivery VRP, I don't have a solution for modelling that as a MIP...

Hi, I do not have an implementation for Gurobi as the number is reported from https://arxiv.org/pdf/1802.04240.pdf, see 'Optimal' in table 2 in appendix C.2. However, you can find some implementations...

Hi! I'm sorry I'm not watching this repo frequently, but this is great. If you create a PR I'm happy to link to this from the README (otherwise I'll see...

Hi! Thanks again for your implementation. I have linked to it in the README.

Hi! This is correct. The reason that there is a steps dimension is that this can be used to evaluate the model on a given tour in a single forward...

I am not sure... this seems like a pretty weird error. Do you have sufficient memory? Are other problems working for you? TensorFlow should not be required, except maybe for...

Hi, See also #29. The reason that there is a steps dimension is that this can be used to evaluate the model on a given tour in a single forward...

Hi! This issue seems related to using Python < 3.8. Please try if it works using Python 3.8. Alternatively, you can roll back [this change](https://github.com/wouterkool/attention-learn-to-route/commit/6c5b78ec74ae007b9bedb3b36c30c84db4b12002) manually. Unfortunately, I am not...

Hi! I think you could try different things. Simplest would be to encode remaining number of vehicles as extra input to the context node (optionally normalized to 0-1 if this...

HI @lzc1432348774, you can just change the data coordinates when using the model, please have a look at the data format in the example notebook.
