ARAC: Adaptive Regularized Multi-Agent Soft Actor-Critic in Graph-Structured Adversarial Games
This research introduces ARAC, an innovative framework for Multi-Agent Reinforcement Learning (MARL) designed to tackle complex graph-structured adversarial games. By integrating an attention-based Graph Neural Network (GNN) and an adaptive divergence regularization mechanism, ARAC effectively addresses challenges like sparse rewards and dynamic interactions. The framework achieves significantly faster convergence, higher success rates, and stronger scalability across varying numbers of agents, demonstrating robust performance in complex, evolving environments.
Executive Impact: Actionable Insights for Enterprise AI
For enterprises deploying multi-agent AI systems in dynamic and complex environments, ARAC offers a robust solution for improved operational efficiency and decision-making. Its ability to learn efficient policies in scenarios with limited feedback, adapt to changing conditions, and scale effectively is crucial for applications ranging from logistics and resource allocation to cybersecurity and autonomous systems.

Sparse Rewards & Dynamic Interactions
Multi-Agent Reinforcement Learning (MARL) in graph-structured adversarial games faces significant hurdles. Agents must coordinate under highly dynamic interactions, but often receive sparse rewards, hindering efficient policy learning. Traditional methods struggle to capture complex local and global relationships, leading to inefficient exploration and suboptimal convergence.
Current Graph Neural Networks (GNNs) like GCN and GAT often face limitations in highly dynamic, many-to-many interaction scenarios, struggling with restricted information propagation and inflexible attention allocation. This makes it difficult to fully capture critical interaction patterns essential for effective decision-making in enterprise systems.
Attention-based GNN & Adaptive Regularization
ARAC addresses these challenges by integrating an attention-based graph neural network (GNN) for modeling agent dependencies. This GNN architecture enhances agents' perception and decision-making by dynamically adjusting information weights based on the current environment state, making it highly adaptable to complex graph structures and dynamic interactions.
Furthermore, ARAC introduces an adaptive divergence regularization mechanism. This allows the algorithm to effectively exploit reference policies for efficient exploration in early training stages while gradually reducing reliance on them as training progresses. This avoids inheriting limitations from potentially suboptimal reference policies, leading to more robust and generalized solutions.
Superior Convergence, Scalability & Generalization
Experiments in pursuit and confrontation scenarios demonstrate ARAC's significant advantages. It achieves faster convergence, reaching optimal success rates much quicker than baselines. It also delivers higher final success rates, consistently outperforming other MARL methods.
Crucially, ARAC exhibits stronger scalability, maintaining stable training and high success rates even with increasing numbers of agents. Its capacity for cross-graph generalization means learned policies transfer effectively to unseen environments, making ARAC a highly effective solution for dynamic and complex enterprise AI deployments.

Case Study: Generalizing Across Unseen Environments
ARAC agents demonstrated remarkable adaptability, maintaining high success rates even when deployed in previously unseen graph environments. For instance, a model trained on Map 1 achieved a 91.2% success rate on its training map, and still performed at 91.0% and 89.0% on Map 2 and Map 3 respectively. This robust cross-graph generalization is crucial for real-world enterprise applications where AI systems must operate effectively in varied and evolving operational landscapes, minimizing retraining costs and deployment friction.
