Multi-party Agent Relation Sampling for Multi-party Ad Hoc Teamwork
This analysis focuses on Multi-party Agent Relation Sampling (MARS), an advanced algorithm for Multi-party Ad Hoc Teamwork (MAHT). MARS enables controlled AI agents to collaborate effectively with multiple, unfamiliar groups of uncontrolled teammates. By leveraging a sparse agent skeleton graph and relational modeling, MARS significantly enhances coordination and adapts to diverse team configurations, outperforming traditional MARL and AHT baselines in speed and performance across various complex tasks like MPE and StarCraft II.
Executive Impact & Strategic Value
MARS represents a significant leap in AI-driven multi-agent coordination, offering strategic advantages for enterprises operating in dynamic and complex environments.

Traditional Multi-Agent Reinforcement Learning (MARL) assumes fixed, fully controlled teams, while Ad Hoc Teamwork (AHT) often focuses on single controlled agents or assumes shared conventions among uncontrolled partners. Multi-party Ad Hoc Teamwork (MAHT), introduced in this research, addresses a more complex real-world scenario where multiple controlled agents must coordinate with multiple, mutually unfamiliar groups of uncontrolled teammates. This presents significant challenges in adapting to diverse behaviors and achieving cross-group coordination, especially with varying group sizes.
MAHT
The Core Challenge: Multi-party Unfamiliar Coordination
Multi-party Agent Relation Sampling (MARS) is proposed to tackle MAHT. It consists of three integrated stages:
- Agent Modeling Network: Uses an encoder-decoder to extract behavioral embeddings from agent trajectories.
- Dynamic Relation Reasoning: Constructs a sparse agent skeleton graph (fully connected within groups, sparse links between groups) and applies a Relational Forward Model (RFM) for iterative message passing. This captures structured behavioral dynamics while reducing computational cost.
- Policy & Value Networks: An actor-critic framework (Independent PPO) conditioned on the learned cooperation embeddings guides policy optimization, allowing controlled agents to adapt and coordinate.

The Power of Sparse Agent Skeletons
The sparse agent skeleton graph is key to MARS's efficiency and effectiveness. Instead of modeling all pairwise connections, which is inefficient for large systems, it treats agents within each group as a fully connected subgraph. Crucially, it constructs a sparse skeleton between groups by randomly linking representative nodes. This design preserves essential coordination pathways (cross-group dependencies) while significantly reducing redundant edges and computational overhead, especially in larger-scale environments.
Value Statement: Reduced complexity, enhanced scalability.
Experiments on the Multi-Agent Particle Environment (MPE) and StarCraft II benchmarks demonstrate MARS's superior performance. It achieves stronger coordination and consistently outperforms representative MARL and AHT baselines across diverse and varying teammates. Notably, MARS also exhibits faster convergence during training.
Ablation studies confirm the crucial roles of both the RFM block in modeling relational dynamics and the sparse skeleton in improving effectiveness and efficiency, particularly in larger-scale tasks.
