The recent developments in the research area of large language models (LLMs) and symbolic reasoning have shown significant advancements in evaluating and enhancing the reasoning capabilities of these models. A notable trend is the shift towards more robust and automated evaluation methods for mathematical reasoning, which aim to address the limitations of traditional static example-based evaluations. This includes the use of symbolic programs to assess the consistency and correctness of LLM outputs across various inputs, highlighting the fragility of current state-of-the-art models in this domain. Additionally, there is a growing interest in bridging the gap between expert models and LLMs, particularly in generating and evaluating human-interpretable commentary in complex decision-making domains like chess. This involves integrating the decision-making strengths of expert models with the linguistic fluency of LLMs to produce accurate and informative explanations. Furthermore, the field is witnessing innovations in autoformalization techniques, where semantic consistency and symbolic equivalence are used to enhance the accuracy of translating natural language into formal language, particularly in mathematics. These advancements underscore the potential of LLMs to act as symbolic reasoners, albeit with necessary supporting components, and suggest a future direction towards more generalized reasoning capabilities. Notably, neuro-symbolic approaches are emerging as a promising method to improve logical reasoning by leveraging LLMs for hypothetical deduction, thereby enhancing the resilience and generalization of reasoning processes.
