About Sinkhorn output

JiayunjieJYJ opened this issue · comments

Thank you for your excellent work, and I have an issue I'd like to discuss with you.
Sinkhorn's output is the result of several rounds of raw and column normalization, but I wonder what happens if two robots pick the same frontier? For example, the following Sinkhorn's output :

final matching matrix:

How does your code solve this problem?

Thanks!

It would be possible that two robots pick the same frontier (they will just try to move towards the same goal position).
However, a well-trained policy will avoid that to achieve higher efficiency.

OK, thanks! Now I have more problems reproducing it. Hope you can help me. Thanks!
