matnet's Issues

I have a question

May I ask if the number of machines in each stage of the FFSP problem needs to be consistent? If it can be a heterogeneous quantity, how should pomo_size be set?

I have a question!

I have a question about job scheduling problem. My my problem is very complicated not like job shop so what if i change the problems define as meta heuristic algorithms as sample for model ?

multi-GPU implementation

In your paper, you mentioned that for n=50/100 large scale data, you adopted a multi-GPU implementation, I wonder if it is possible to provide a multi-GPU version of the code

I want ask a question?

Sorry because i dont understand the code and I need your help ! I have two question

  • The first question: I understand that the score and aug_score is the tour length. But went i test it with my own dataset, i change the scale so the ans is different. So i want to ask that the train scale and test scale must be the same ?
  • The second question: I know that max_pomo_reward.max(dim=0) is the best tour and I dont know how to get it, and I know self.env.slected_node_list is the tour but how i can get it from the best tour ?
    TKS!!

The model file is not exist

Hi, it seems that the trained model saved in results/saved_atsp_model is not available now. I tried to get the model from git lfs, but it shows the model does not exist on the server. Could you please solve this problem? Thanks very much.

Ask some questions

Have you ever tried to solve the dynamic vehicle scheduling problem with this model?

Hope you can help me

If I met the Multiple data matrices, what should I do, May I do like this : scores = torch.stack((dot_product_score, cost_mat1, cost_mat2, cost_mat3 ), dim=4).
There may also be papers that I didn't fully understand, forgive me for being a newbie

I have a question?

max_aug_pomo_reward, _ = max_pomo_reward.max(dim=0) # get best results from augmentation
# shape: (batch,)
aug_score = -max_aug_pomo_reward.float().mean() # negative sign to make positive value

I want to ask why you use .mean() but we want to get the best result
