Before revision: In this paper, I propose actor-critic approaches by introducing an actor policy on QMIX ( [ 1 ] ) , which can remove the monotonicity constraint of QMIX and implement a non-monotonic value function factorization for joint action-value  .
After revision: In this paper, I propose actor-critic approaches by introducing an actor policy on QMIX ( [ 9 ] ) , which can remove the monotonicity constraint of QMIX and implement a non-monotonic value function factorization for joint action-value .
