QMIX: Monotonic Value Function Factorisation for Deep Multi-Agent Reinforcement Learning

TLDR
QMIX employs a network that estimates joint action-values as a complex non-linear combination of per-agent values that condition only on local observations, and structurally enforce that the joint-action value is monotonic in the per- agent values, which allows tractable maximisation of the jointaction-value in off-policy learning.

Hierarchical Deep Multiagent Reinforcement Learning

TL;DR: This paper decomposes the original MARL problem into hierarchies and investigates how effective policies can be learned hierarchically in synchronous/asynchronous hierarchical MARL frameworks, and proposes a new experience replay mechanism, named as Augmented Concurrent Experience Replay (ACER).

Long short-term memory

TL;DR: A novel, efficient, gradient based method called long short-term memory (LSTM) is introduced, which can learn to bridge minimal time lags in excess of 1000 discrete-time steps by enforcing constant error flow through constant error carousels within special units.

Empirical evaluation of gated recurrent neural networks on sequence modeling

TL;DR: These advanced recurrent units that implement a gating mechanism, such as a long short-term memory (LSTM) unit and a recently proposed gated recurrent unit (GRU), are found to be comparable to LSTM.

Deep reinforcement learning with double Q-learning

TL;DR: In this article, the authors show that the DQN algorithm suffers from substantial overestimation in some games in the Atari 2600 domain, and they propose a specific adaptation to the algorithm and show that this algorithm not only reduces the observed overestimations, but also leads to much better performance on several games.
