Researchers at OpenAI have developed an algorithm called LOLA (Learning with Opponent-Learning Awareness) that takes into account the fact that other agents are also learning. This allows LOLA to discover strategies that balance self-interest and cooperation, such as tit-for-tat in the prisoner's dilemma. The algorithm is a step towards creating AI systems that can model and understand the behavior of other minds. --- Why it matters: This matters because it could lead to more effective collaboration between AI agents, which is crucial for tasks like multi-agent planning and decision-making. It also has implications for game theory and understanding how humans interact with each other in complex situations. Source: https://openai.com/index/learning-to-model-other-minds
