EngiAgent: Fully Connected Coordination of LLM Agents for Solving Open-ended Engineering Problems with Feasible Solutions
Engineering problem solving is a critical aspect of real-world decision-making, often requiring intricate mathematical formulations that both represent complex problems and yield feasible solutions within data and physical constraints. Traditional mathematical problem-solving approaches are typically confined to predefined formulations; however, engineering tasks necessitate a more open-ended analysis, feasibility-driven modeling, and iterative refinement. Recent advancements in large language models (LLMs) have showcased their strong capabilities in reasoning and code generation, yet they frequently falter when it comes to ensuring feasibility in engineering contexts. This limitation restricts their practical applications in engineering problem-solving scenarios.
To tackle this significant challenge, researchers have introduced EngiAgent, an innovative multi-agent system equipped with a fully connected coordinator. This system simulates expert workflows by utilizing specialized agents dedicated to various tasks, including problem analysis, modeling, verification, solving, and solution evaluation. The introduction of a fully connected coordinator facilitates flexible feedback routing, thereby overcoming the limitations associated with previous pipeline-based reflection methods and ensuring feasibility at every stage of the problem-solving process.
