Web: https: . In general, there are two types of multi-agent systems: independent and cooperative systems. Multiagent reinforcement learning: theoretical framework and an algorithm. This paper proposes two methods that address this problem: 1) using a multi-agent variant of importance sampling to naturally decay obsolete data and 2) conditioning each agent's value function on a fingerprint that disambiguates the age of the data sampled from the replay memory. Methodology Multi-agent Reinforcement Learning 238 papers with code 3 benchmarks 6 datasets The target of Multi-agent Reinforcement Learning is to solve complex problems by integrating multiple agents that focus on different sub-tasks. Learn cutting-edge deep reinforcement learning algorithmsfrom Deep Q-Networks (DQN) to Deep Deterministic Policy Gradients (DDPG). Each category is a potential start point for you to start your research. The possible actions from each state are: 1.UP 2.DOWN 3.RIGHT 4.LEFT Let's set the rewards now, 1.A reward of +10 to successfully reach the Goal (G). Team Members: Moksh Jain; Mahir Jain; Madhuparna Bhowmik; Akash Nair; Mentor . Q-learning is a foundational method for reinforcement learning.
