Is this issue still active @KelSolaar ? If so, I hope to give a contribution for it.
Thanks.

Hi @starkfan007, yes it is still up!

Hi @KelSolaar, I am a bit confused about some of the statements in the paper.
The first question is how to understand the previous state and how to define the previous state in the code. I didn't understand this part very well.
The second question is about D factor. There is no corresponding calculation formula in the paper. According to Table 1, D factor seems to be an empirical parameter adjusted through different model experiments.
Thanks!

Hello @starkfan007,

Sorry, I haven't had time to check the paper details yet! Let me get back to you!

I'm familiar with this paper. But it would be much easier for me to discuss on a call or voice chat. Feel free to reach out.
