REINS: A Self-Evolving Agent Harness for Real-Time Trajectory Planning

REINS: A Self-Evolving Agent Harness for Real-Time Trajectory Planning

Summary

This research introduces REINS, a runtime harness designed for real-time trajectory planning that wraps an LLM's reasoning loop with tool dispatch, verification, and persistent memory. The system grounds LLM outputs to a learned variable-level dynamics model, verifies them via calibrated predicates and forward rollout, and consolidates results into an indexed rule memory serving future scenes in O(log n) time. By closing a self-evolution loop where familiar scenes resolve via memory lookup and novel scenes invoke the LLM to enrich memory, REINS achieves over 98% compliance, nearly 50% collision reduction, and 1.9-4.6 ms latency on simulated and real-world benchmarks without modifying LLM weights.

Editorial context

The paper proposes REINS, a runtime harness that grounds LLM outputs to learned dynamics models and consolidates verified trajectories into an indexed rule memory to meet real-time constraints while self-evolving.
