Max Plus Method for Joint Action Selection: Use-Case and Implementation

Good Day Folks:

Could anyone point me towards a successful implementation (or proxy)
of the Max-Plus method for joint selection?

If not are there any Markov Decision Process (MDP) or multi-agent
Markov decision process (MMDP) model implementations that are
fairly current (less than 3 years old).

Thank you,
