The Convergence of LLMs and Genetic Programming
This section explores the fundamental integration of Large Language Models (LLMs) into Genetic Programming (GP) frameworks. LLMs act as sophisticated mutation operators, introducing semantically meaningful variations into agent behaviors. This novel approach, termed LLM-GP, leverages the advanced code-generation capabilities of LLMs to overcome the limitations of traditional, syntax-reliant GP methods. By generating syntactically correct and functionally coherent code, LLM-GP promises more innovative and effective evolutionary processes for complex problems.
Optimizing LLM Output through Prompt Engineering
The efficacy of LLMs as evolutionary operators is highly dependent on the prompting strategies employed. We systematically compare zero-shot, one-shot, and two-shot prompting methods to evaluate their impact on the relevance, diversity, and quality of LLM-generated content. Furthermore, we investigate the effect of prompting for comment generation, hypothesizing that explicit self-explanation by the LLM enhances its ability to reason with semantic information, leading to more intelligent code mutations. Our findings provide crucial insights into crafting effective prompts for LLM-driven evolutionary algorithms.
Evolving at a Higher Abstraction: Pseudocode Mutation
A key innovation in this study is the proposition of evolving agent behaviors using pseudocode representations. Instead of mutating executable code directly, evolution operates on high-level natural language descriptions (pseudocode), which are then translated into executable code by a separate LLM step. This approach capitalizes on LLMs' extensive training on natural language and pseudocode, potentially enabling the discovery of more abstract and innovative solutions. It also aligns with principles of explainable AI, offering enhanced interpretability of evolved agent behaviors, though translation fidelity remains a challenge.
LLM-GP for Complex Multi-Agent Systems
This research specifically applies LLM-GP techniques to evolve agent controllers within multi-agent systems (MAS). We introduce three NetLogo-based multi-agent environments designed as benchmarks for evaluating LLM-GP in MAS: Collection Simple, Collection Hazardous, and Collection Resources. These environments require agents to develop complex strategies for resource collection, hazard avoidance, and resource management. The application of LLM-GP in MAS aims to optimize collective outcomes, a significant challenge in artificial intelligence, by enabling agents to co-evolve sophisticated and adaptive behaviors.

Case Study: Agent Behavior in Hazardous Environments
In the Collection Hazardous environment, agents are tasked with collecting food while actively avoiding poison. Our research shows that LLM-driven mutation with comment generation significantly enhanced agent performance in this complex scenario, outperforming direct code mutations. This suggests that the LLM's ability to "reason" through comments allows for more robust and adaptive behavioral evolution, enabling agents to balance conflicting objectives effectively.
- Hazardous Environment: Commented code improved fitness by over 50% compared to zero-shot direct code mutations.
- Simple Environment: Faster convergence to optimal strategies was observed across all few-shot prompting conditions with commented code.
- Resource Management: Agents evolved sophisticated timing for resource deposits to maximize cumulative points while minimizing weight penalties.
