* To the best of our knowledge, this is the first attempt to explore the full spectrum of reinforcement learning agents (multi-armed bandits, contextual bandits and reinforcement learning) in the sequential social dilemma. This mental variants section supersedes and extends our work arXiv:1706.02897 (MAB), arXiv:2005.04544 (CB) and arXiv:1906.11286 (RL) into the multi-agent setting
