The network structure about online-3d-bpp-pct HOT 6 CLOSED

Hi, thanks for your attention. In the work of PCT, we use the graph attention network to extract the features of the problem. This part of the code is mainly integrated in 'attention_model.py' and 'graph_encoder.py'. Unlike PCT, our previous work mainly uses CNN to extract question features.

Dear author:
Thanks for your sharing!
I would like to consult you about the network structure of DRL.Which part of the project is this part of the code mainly integrated into?Is the DRL structure same as your previous work in 2021?
Thanks for your sharing again! Best wishes for you!

In this work, we use the graph attention network (GAT) to extract the features of the problem. This part of the code is mainly integrated in 'attention_model.py' and 'graph_encoder.py'. Different from PCT, our previous work in 2021 mainly uses CNN to extract question features.

Hello, thank you very much for your reply. I noticed the difference and connection between the graph neural network in the PCT article and the CNN part in the DRL article.  Regarding the deep reinforcement learning network structure in the PCT article, I noticed that you still use the acktr algorithm and network structure in the DRL article.  Therefore,I would like to consult you about if you have tried other deep learning algorithms such as TRPO, SAC, ACER, etc. methods? Or are there obvious reasons these algorithms are inferior to the acktr algorithm and we don't need to try?

Our experiment results show that ACKTR works the best among mainstream RL algs. But we also encourage you to try other SOTA RL algs, maybe you can get different and even better results.
