LLM Agents: Reasoning and Quality Hillclimbing Approaches (Published)
This comprehensive article examines the evolution of reasoning capabilities in Large Language Model (LLM) agents, focusing on advanced frameworks and quality improvement approaches. The article explores key developments in agent reasoning mechanisms, including Tree-of-Thought and hierarchical reasoning structures, which have transformed problem-solving capabilities beyond simple input-output paradigms. It analyzes quality hillclimbing techniques such as Self-Refine and OPRO that systematically enhance model outputs through iterative refinement and optimization. The article presents empirical results quantifying improvements in reasoning quality and computational efficiency, followed by practical implementation frameworks and architectural considerations for deploying these systems at scale. Future directions in advanced reasoning paradigms and optimization methods are discussed alongside real-world applications in business decision-making and technical problem-solving that demonstrate the practical impact of these theoretical advances.
Keywords: hierarchical decomposition, large language models, multi-agent systems, quality hillclimbing, reasoning frameworks
