LLM-Enhanced metaheuristics with single-shot and few-shot learning for multi-robot exploration tasks
This study explores how Large Language Models (LLMs) like GPT, Gemini, and Claude can enhance multi-robot exploration. It focuses on zero-shot and few-shot learning to improve Particle Swarm Optimization (PSO) for navigating complex environments and overcoming issues like local optima. Experimental results show strong potential for LLMs in refining these strategies.
Key Performance Indicators & Business Impact
Integrating LLMs into multi-robot exploration algorithms offers a transformative approach to achieving higher efficiency, adaptability, and reliability in dynamic, obstacle-rich environments. This not only accelerates mapping processes but also significantly reduces operational costs by minimizing redundant exploration and preventing mission failures.

Hybrid CME-PSO with LLM Enhancement
The core methodology integrates Coordinated Multi-Robot Exploration (CME) with Particle Swarm Optimization (PSO). CME provides structured coverage, while PSO adds adaptive, swarm-intelligence-driven path optimization. LLMs are then layered on top to refine these strategies, particularly in how robots navigate unknown environments, avoid obstacles, and balance exploration vs. exploitation.

Performance Gains in Complex Environments
The integration of LLMs, especially through few-shot learning, yielded significant performance improvements. GPT-4, Gemini 1.5, and Claude 3.5 Sonnet variants of CME-PSO consistently outperformed the baseline CME and CME-PSO in terms of exploration coverage, time efficiency, and failure rates, particularly in obstacle-rich maps.

% exploration coverage achieved by LLM-CME-PSO-GPT-4 on Map 5.
Impact in Obstacle-Rich Environments (Map 3)
In Map 3, deterministic CME achieved only 2.26% coverage, while CME-PSO improved it to 89.85%. However, LLM-CME-PSO-GPT-4 reached an impressive 97.02%, showcasing its superior adaptability and decision-making capabilities in highly complex, obstacle-dense scenarios. This highlights the LLM's role in overcoming local optima and inefficient exploration patterns.
Takeaway: LLMs dramatically improve navigation and coverage in highly complex, obstacle-rich environments by enabling adaptive, intelligent pathfinding.
Real-World Deployment & Future Outlook
The LLM-enhanced CME-PSO framework is designed for direct adaptability to real-world robotic systems, such as TurtleBot 3 with ROS. The strategies, optimized offline, impose minimal computational overhead during runtime, making them suitable for resource-constrained platforms. Future work involves real-time LLM integration via APIs and exploring new LLM architectures.
