Towards Reliable and Robust LLM Planning: Symbolic Feedback-Driven Iterative Self-Refinement Framework

arXiv:2606.27757v1 Announce Type: new Abstract: Large language models (LLMs) have attracted widespread attention from academia and industry, yet their deployment raises critical security concerns regarding robustness and reliability. Planning, a core component of intelligent behavior, remains challenging for LLMs, which often produce infeasible or incorrect solutions in long-horizon decision-making tasks due to inherent complexity. In this paper, we propose a symbolic feedback-driven iterative self-refinement framework to enhance the robustness and reliability of LLMs in long-horizon planning.

Why this matters
Why now

The rapid advancement and widespread deployment of LLMs highlight current limitations in robustness and reliability, making solutions for planning critical for further integration into complex systems.

Why it’s important

Improving LLM planning directly addresses a core barrier to autonomous AI agent development, increasing their utility and trustworthiness in real-world, long-horizon tasks.

What changes

The introduction of symbolic feedback and iterative self-refinement promises more reliable and robust LLM outputs for complex planning, potentially accelerating the deployment of advanced AI agents.
