PhD position on understanding algorithmic collusion by decentralized multiagent reinforcement learning

Published Deadline Location
2 Feb 4 Mar Enschede

Job description

How can we design decentralized multiagent reinforcement learning (MARL) algorithms with equilibrium selection control? This is the central research question of this PhD project. We will be particularly interested in determining whether decentralized MARL algorithms used for pricing or trading can learn to collaborate to raise prices. By developing an understanding of if and how this is possible, we can inform policymakers on how to regulate the use of algorithms in such environments.

To address this issue, we will begin by characterizing the probability of reaching different equilibria under the dynamics of provably convergent decentralized MARL algorithms. With this characterization in hand, we will study how design choices in the algorithmic structure affect these probabilities. These two steps will initially be executed for simple environments and with deterministic dynamics, and then they will be scaled up to more complex environments with stochastic dynamics. Our starting point will be the Decentralized Q-learning algorithm, as it offers significant flexibility in its design and is provably convergent in a large class of games.
