Before revision:  The coexistence problem was modeled as a  Dec-POMDP  and Bayesian approach was adopted for policy learning with nonparametric prior to accommodate the uncertainty of policy for different agents.
After revision:  The coexistence problem was modeled as a decentralized partially observable Markov decision process ( Dec-POMDP and Bayesian approach was adopted for policy learning with nonparametric prior to accommodate the uncertainty of policy for different agents.
