Multi Objective Deep Reinforcement Learning

Multi-objective deep reinforcement learning (MODRL) addresses the challenge of optimizing multiple, often conflicting, objectives simultaneously within complex systems using deep neural networks. Current research focuses on applying MODRL to diverse real-world problems, including traffic control, resource allocation in e-commerce, and infrastructure maintenance, employing algorithms like Deep Q-Networks (DQN) variants, Proximal Policy Optimization (PPO), and evolutionary multi-objective approaches. These advancements enable the development of more robust and adaptable systems by directly optimizing for multiple performance metrics, leading to improved efficiency, safety, and fairness across various applications.
