Multi-robot navigation in social mini-games: definitions, taxonomy, and algorithms
This survey paper introduces a unified taxonomy, definitions, and evaluation protocols for Multi-Robot Navigation (MRN) in 'Social Mini-Games' (SMGs). SMGs are high-agency, constrained environments (e.g., doorways, intersections) where robots compete for space, leading to deadlocks or collisions with other robots and humans if not properly managed. Traditional MRN approaches often fail in SMGs, leading to ad-hoc research. The paper aims to streamline future research by classifying existing SMG solvers (MARL, MAPF, Optimization, Heuristics) based on design choices like coordination, communication, deadlock handling, invasiveness, cooperation, and observability. It defines SMGs, outlines evaluation metrics (Average AV, Average Delay, Path Deviation, Flow Rate, Fairness, Influence Score), and discusses representative solvers (CADRL, Right-Hand-Rule, Auction-Based, IMPC-DR, ORCA-MAPF). Finally, it highlights future directions and open challenges, including visual inputs, human-robot interaction, and digital twins, and provides an open-source library (SMGLib) for benchmarking.

MARL Approaches
Multi-Agent Reinforcement Learning (MARL) extends single-agent RL to environments with multiple learning agents, addressing non-stationarity. In SMGs, MARL models strategic coupling and heterogeneous costs. It requires safety layers, symmetry-breaking priors, and partial observability handling, and can improve fairness and reduce invasiveness.

MAPF Algorithms
Multi-Agent Path Finding (MAPF) algorithms compute conflict-free paths on a graph. In SMGs, MAPF acts as a local joint-planning subroutine to resolve conflicts and deadlocks, often in discrete, centralized, fully cooperative, and observable settings. While guaranteeing optimality, it can be computationally expensive.

Optimization-Based Methods
Optimization-based approaches formulate navigation as a constrained optimal control problem, minimizing costs subject to system dynamics and collision avoidance constraints. They expose SMG structure via explicit constraints (safety, rules-of-the-road) and multi-objective costs. Adding priority or turn-taking constraints yields predictable equilibria.

SMG Implementation in Warehouse Logistics
A leading logistics provider faced frequent deadlocks and collisions among autonomous mobile robots (AMRs) in narrow warehouse corridors and at intersections. By implementing SMG-aware navigation algorithms, specifically a hybrid ORCA-MAPF approach, they reduced collision incidents by 75% and improved throughput by 20% during peak hours. The system dynamically identified 'mini-games' at bottlenecks, applying real-time conflict resolution without central control, demonstrating enhanced efficiency and safety. This led to a significant reduction in operational downtime and a clearer path for further scaling their AMR fleet.
