• Abstract summary: We propose to utilize market forces to provide incentives for agents to become cooperative. As demonstrated in an iterated version of the Prisoner's Dilemma, the proposed market formulation can change the dynamics of the game. We empirically find that the presence of markets can improve both the overall result and agent individual returns via their trading activities.

• Abstract: Some of the most relevant future applications of multi-agent systems like autonomous driving or factories as a service display mixed-motive scenarios, where agents might have conflicting goals. In these settings agents are likely to learn undesirable outcomes in terms of cooperation under independent learning, such as overly greedy behavior. Motivated from real world societies, in this work we propose to utilize market forces to provide incentives for agents to become cooperative. As demonstrated in an iterated version of the Prisoner's Dilemma, the proposed market formulation can change the dynamics of the game to consistently learn cooperative policies. Further we evaluate our approach in spatially and temporally extended settings for varying numbers of agents. We empirically find that the presence of markets can improve both the overall result and agent individual returns via their trading activities.

• Learning to Balance Altruism and Self-interest Based on Empathy in Mixed-Motive Games [47.8980880888222]
  Multi-agent scenarios often involve mixed motives, demanding altruistic agents capable of self-protection against potential exploitation. We propose LASE Learning to balance Altruism and Self-interest based on Empathy. LASE allocates a portion of its rewards to co-players as gifts, with this allocation adapting dynamically based on the social relationship.

• Cooperation Dynamics in Multi-Agent Systems: Exploring Game-Theoretic Scenarios with Mean-Field Equilibria [0.0]
  This paper investigates strategies to invoke cooperation in game-theoretic scenarios, namely the Iterated Prisoner's Dilemma. Existing cooperative strategies are analyzed for their effectiveness in promoting group-oriented behavior in repeated games. The study extends to scenarios with exponentially growing agent populations.

  We propose a multi-agent framework framework that can collaboratively adjust its composition as a greater-than-the-sum-of-its-parts system. Our experiments demonstrate that framework framework can effectively deploy multi-agent groups that outperform a single agent. In view of these behaviors, we discuss some possible strategies to leverage positive ones and mitigate negative ones for improving the collaborative potential of multi-agent groups.

• Learning to Participate through Trading of Reward Shares [1.5484595752241124]
  We propose a method inspired by the stock market, where agents have the opportunity to participate in other agents' returns by acquiring reward shares. Intuitively, an agent may learn to act according to the common interest when being directly affected by the other agents' rewards.

  We study a game between liquidity provider and liquidity taker agents interacting in an over-the-counter market.

We show convergence rates for our multi-agent policy gradient algorithm under a transitivity assumption.

  In multi-agent reinforcement learning systems, the actions of one agent can have a negative impact on the rewards of other agents. This work applies a trading approach to a simulated scheduling environment, where the agents are responsible for the assignment of incoming jobs to compute cores. The agents can trade the usage right of computational cores to process high-priority, high-reward jobs faster than low-priority, low-reward jobs.

  We show that deep reinforcement learning can discover stable solutions that are epsilon-Nash equilibria for a meta-game over agent types. Our approach is more flexible and does not need unrealistic assumptions, e.g., market clearing. We demonstrate our approach in real-business-cycle models, a representative family of DGE models, with 100 worker-consumers, 10 firms, and a government who taxes and redistributes.

  In this paper, we model repeated Cournot games with non-stationary demand. The set of arms/actions that an agent can choose from represents discrete production quantities. We propose a novel algorithm 'Adaptive with Weighted Exploration (AWE) $epsilon$-greedy' which is remotely based on the well-known $epsilon$-greedy approach.
