A Neuro-Symbolic Approach for Reliable Proof Generation with LLMs: A Case Study in Euclidean Geometry
Large Language Models (LLMs) often struggle with the rigorous logical deduction required for mathematical proof generation. This research introduces a neuro-symbolic approach that combines LLM generative strengths with structured components: analogical guidance and symbolic verification. Tested on Euclidean geometry problems, our method significantly improves proof accuracy, reduces costs, and enhances reliability, making provably correct conclusions achievable for complex tasks.

This iterative process ensures that generated proofs are not only plausible but formally verifiable, dramatically improving the trustworthiness of LLM outputs in critical applications.
Leveraging Analogical Guidance
Analogical reasoning is a fundamental aspect of human problem-solving. By retrieving structurally similar problems and their known proofs, we provide LLMs with crucial in-context learning examples, significantly enhancing their ability to construct new, correct proofs and reduce the search space for relevant theorems.

The strategic selection of relevant theorems drastically reduces the LLM's context window, leading to more efficient and accurate proof generation. This targeted approach is a key differentiator for enterprise-grade formal reasoning.
Enhanced Reliability with Symbolic Verification
A critical component of our neuro-symbolic system is the symbolic verifier, which provides iterative, structured feedback to the LLM. This feedback loop allows the model to self-correct and refine its generated proofs until a valid solution is obtained, addressing the inherent unreliability of purely generative models.

Average Accuracy Gain from Verifier Feedback
The verifier identifies three tiers of errors: syntax violations, premise violations, and goal not reached, guiding the LLM to specific issues. This iterative correction process leads to significant performance boosts, with gains ranging from 10% to 40% per difficulty level for the base model, ensuring high-quality, provably correct outputs.
Robustness Across Diverse LLM Architectures
Our methodology demonstrates robust performance improvements across different state-of-the-art LLMs, proving its generalizability beyond a single model. This cross-model consistency highlights the strength of the neuro-symbolic framework, rather than relying on the specific nuances of any individual LLM.
Cross-Model Performance: OpenAI o1 vs. Gemini-2.5-Flash
Our core experiments were replicated with both OpenAI's o1 model and Gemini-2.5-Flash, showcasing consistent trends and substantial gains. For instance, in a single run with verifier feedback, accuracy improved from 58% to 74% for Gemini-2.5-Flash, demonstrating its effectiveness even with an inherently stronger base model. When allowing multiple runs and retries, Gemini-2.5-Flash reached an impressive 86% average accuracy, significantly exceeding its baseline of 22%.
This consistent improvement across different LLM families underscores the universal applicability and value of combining analogical guidance and symbolic verification for reliable proof generation in enterprise AI systems.
