Graph Reinforcement Learning

Graph Reinforcement Learning (GRL) combines the power of graph neural networks (GNNs) with reinforcement learning (RL) to solve complex decision-making problems on graph-structured data. Current research focuses on applying GRL to diverse domains, including robotics, traffic control, power grids, and resource allocation, often employing GNN architectures like graph convolutional networks and graph attention networks alongside RL algorithms such as Proximal Policy Optimization (PPO) and Deep Deterministic Policy Gradient (DDPG). This approach offers significant advantages in handling large-scale, dynamic systems with intricate relationships between entities, leading to improved efficiency and adaptability in various real-world applications.
