Deadlock Free

Deadlock-free operation, crucial for multi-agent systems like robot swarms and autonomous vehicles, aims to prevent situations where agents block each other, hindering progress. Current research focuses on developing decentralized algorithms, often employing hierarchical planning with short, medium, and long-horizon decision-making modules, or leveraging techniques like control barrier functions and strategic pseudo-goal perturbations to resolve potential deadlocks proactively and efficiently. These advancements are significant for improving the safety, efficiency, and reliability of complex multi-agent systems in various applications, from warehouse automation to traffic management.
