API support for Bidding

[mingyangjiao]

May I ask if the latest version support Bidding? In the real game, the three players start with bidding and the one with highest bid become the landlord. In this projects, it seems like we ignore and skip bidding? Could you tell me if there's a way to make bidding decision with DouZero AI?

thank you!

Hi mingyangjiao,

Thanks for your interest in the project!

You're absolutely right that in real-world Doudizhu games, bidding is an important phase where players compete to become the landlord. However, the original DouZero implementation we based on doesn't include bidding functionality - it focuses only on the card-playing phase after the landlord has been determined.

Currently this API doesn't support bidding decisions, but you could potentially implement a simple bidding module yourself. Some possible approaches:

• Create rule-based bidding logic based on hand strength evaluation

• Use simple heuristics like counting high-value cards in hand

Hey~

Thank you for the detailed response and suggestions. I did some further digging:

https://www.douzero.org/bid

DouZero do have a version with Bid, but unfortunately it had not been open-sourced yet.

Other than this, shout out for architecting your project with a web-based API (instead of an CLI tool). HTTP foundation makes it super extensible for further development, I love how it handles concurrent games without tight coupling.

Keep up with the good work. Thanks!

Thank you for pointing out the bidding implementation from the official DouZero team — I wasn’t aware of that unpublished feature before, so I really appreciate you sharing it!

You're absolutely right - transitioning from CLI to HTTP API unlocks many possibilities. As I continue learning about API development, I'll make this an improvement focus in the project's evolution.

Thanks again for your thoughtful suggestions and support!
