(2403.16097)Abstract
Transformer-based LLMs have demonstrated significant potential in addressing logic problems. capitalizing on the great capabilities of LLMs for code-related activities, several frameworks leveraging logical solvers for logic reasoning have been proposed recently. While existing research predominantly focuses on viewing LLMs as natural language logic solvers or translators, their roles as logic code interpreters and executors have received limited attention. This study explore a novel aspect, namely logic code simulation, which forces LLMs to emulate logical solvers in predicting the results of logical programs. To further investigate this novel task, we formulate our three research questions: Can LLMs efficiently simulate the outputs of logic codes? What strength arises along with logic code simulation? And what pitfalls? To address these inquiries, we curate three novel datasets tailored for the logic code simulation task and undertake thorough experiments to establish the baseline performance of LLMs in code simulation. Subsequently, we introduce a pioneering LLM-based code simulation technique, Dual Chains of Logic (DCoL). This technique advocates a dual-path thinking approach for LLMs, which has demonstrated state-of-the-art performance compared to other LLM prompt strategies, achieving a notable improvement in accuracy by 7.06% with GPT-4-Turbo.

Exploring the Frontier of Logic Code Simulation with LLMs
Introduction
In recent advancements within the field of artificial intelligence and software engineering, the potential of transformer-based LLMs to tackle logic problems has become increasingly evident. This study ventures into the relatively unexplored territory of using LLMs not just as tools for understanding or translating logic codes but as simulators that can predict the outcomes of logical programs. By formulating novel research questions and introducing a unique dataset and method, this paper boldly steps into assessing the capacity of LLMs to act as logic solvers themselves.
Logic Code Simulation with LLMs
At the core of this research lies the question of whether LLMs can effectively simulate logic codes, essentially emulating the output that would result from executing the logic within a program. This involves comprehending the program's logic, engaging in logic reasoning, and converting the reasoning process back into the expected outcome of code execution. Through extensive experimentation using the newly curated datasets tailored specifically for logic code simulation, this paper unveils the groundbreaking technique Dual Chains of Logic (DCoL). This method significantly outperforms existing strategies in logic code simulation, marking a substantial step forward in the capabilities of LLMs.
Dataset and Experimentation
Unique to this study, new datasets derived from the solver community are introduced, namely Z3Tutorial, Z3Test, and SMTSim, gathering diverse logic simulation problems. These datasets are pivotal in systematically evaluating the performance of various LLMs, including GPT-3.5 Turbo, GPT-4 Turbo, and the LLaMA-2-13B models, against the proposed logic code simulation task. The innovation doesn't stop there; the introduction of the Dual Chains of Logic (DCoL) technique encourages LLMs to engage in a dual-path reasoning approach. This method substantially enhances the models' accuracy and robustness in code simulation tasks, with GPT-4-Turbo witnessing a remarkable 7.06% improvement in accuracy.
Findings and Implications
The experiments conducted reveal intriguing insights into the capabilities and limitations of current LLMs in simulating logic code. GPT series models show a strong aptitude for logic simulation, highlighting their advanced understanding and reasoning abilities. Meanwhile, the LLaMA models, though effective, exhibit a tendency to generate a higher incidence of "unknown" outcomes, suggesting a potential area for model refinement.
A notable strength of LLMs, as identified in this study, is their capacity to process and simulate logic codes even in the presence of syntax errors, showcasing a remarkable level of robustness and flexibility. Moreover, the paper highlights LLMs' potential in transcending some of the theoretical limitations inherent to traditional solvers, providing a promising avenue for future developments in logic problem-solving.
Looking Ahead
While the results of this study are promising, they also underscore the challenges and complexities of logic code simulation with LLMs. The DCoL method represents a significant advancement, yet there remains ample scope for refinement and exploration. Future work will aim not only to enhance the performance and applicability of DCoL but also to extend its utility beyond the realm of logic solvers. The integration of LLMs with additional knowledge retrieval and storage techniques could pave the way for practical applications that efficiently simulate complex logic programs in real-life scenarios.
Conclusion
This study marks a pivotal moment in the exploration of LLMs' capabilities as logic code simulators. By proposing a novel task, introducing a dedicated framework, and systematically evaluating the performance across various datasets and models, the research opens up new horizons in the application of LLMs in software engineering and beyond. The findings not only provide a solid foundation for future inquiry but also inspire the continued evolution of AI-driven logic simulation methodologies.
