Physics-grounded LLM agent Mimir optimizes irrigation control

Researchers have developed Mimir, a novel LLM agent designed for long-horizon physical control tasks, specifically focusing on irrigation management. Mimir operates on two repair timescales: a fast loop for numerical checking and revision of LLM outputs before execution, and a slow loop for consolidating recurrent failure patterns into persistent contextual principles. This approach allows the agent to improve from experience without altering fundamental physical rules. In evaluations across various sites, crops, and years, Mimir achieved the lowest aggregate control cost, using approximately 51% less irrigation than historical schedules. Studies indicated that larger LLM sizes did not yield monotonic gains in performance, suggesting that specialized agent architecture is more critical than model scale for such applications. AI

IMPACT Demonstrates a novel approach to applying LLM agents to long-horizon physical control problems, potentially influencing future agent design for real-world applications.

    Mimir: Physics-Grounded LLM Agents for Long-Horizon Irrigation Control

    arXiv:2610.02038v1 Announce Type: new Abstract: Large language model (LLM) agents increasingly combine reasoning, tool use, and action, but most evidence comes from episodic tasks with relatively immediate feedback and reset failures. Long-running physical control operates in a d…
