The EvoStage Paradigm
EvoStage is a novel evolutionary paradigm that bridges the gap between the rigorous demands of industrial-scale algorithm design and LLM-based methods. It leverages a multi-component structure: an evolutionary framework, Stagewise Design, a multi-agent system, and a global-local perspective mechanism. This holistic approach enables LLMs to tackle complex design tasks by breaking them down and refining them iteratively with contextual feedback.
Why It Matters: This paradigm fundamentally enhances LLM capabilities for multi-step reasoning, making algorithm design more robust and less prone to 'hallucinations' in real-world industrial settings with limited data and evaluation budgets.
Stagewise Design for LLMs
Inspired by Chain-of-Thought (CoT), Stagewise Design decomposes the complex algorithm design task into multiple simpler, sequential stages. Each stage is a subtask where LLM agents receive real-time intermediate feedback on algorithm-execution outcomes, allowing for iterative refinement.
Why It Matters: This approach significantly reduces the complexity for LLMs, enables timely verification of design quality, and helps LLM agents update their domain-specific understanding of the target problem, leading to higher-quality, more reliable algorithms.
Collaborative Multi-Agent System
To fully leverage LLM potential, EvoStage employs a multi-agent system. Individual LLM coder agents are assigned specific algorithm components to design, while a dedicated coordinator agent performs reflection on current stage information and provides design guidelines for subsequent stages.
Why It Matters: This structure cuts down the algorithm design space, allows LLMs to specialize, reduces grammatical errors, and ensures consistency and alignment on the overall optimization direction, preventing agents from falling into local optima by over-focusing on subtask optimization.
Global-Local Optimization Balance
This mechanism incorporates both local perspective (Stagewise-Design, stage-by-stage refinement) and global perspective operators (Global-Explore for novel designs, Global-Enhance for performance tuning). These operators enable LLMs to analyze multi-stage heuristic references and generate new algorithms, either step-by-step or in one shot.
Why It Matters: By balancing local subtask optimization with global algorithm design, this mechanism helps LLMs escape local optima, promotes exploration of diverse designs, and enhances the exploitation of promising candidates, leading to more robust and high-performing solutions.

Case Study: Record-Breaking Efficiency in 3D Chip Placement
Context: EvoStage was deployed on a commercial-grade 3D chip placement tool to optimize the parameter configuration schedules for the Adam optimizer (learning rate and optimization steps) in a real-world industrial 3D chip design problem. This task is crucial for VLSI circuits, directly impacting Power, Performance, and Area (PPA).
Approach: EvoStage autonomously designed the learning rate and density weight schedules by applying its stagewise design, multi-agent system, and global-local perspective mechanisms. It iteratively refined these schedules based on real-time intermediate feedback, outperforming existing human-expert and LLM-based solutions.
Results: The results were groundbreaking: a 9.24% improvement in half-perimeter wirelength (HPWL) on the logic die, a 7.51% improvement on the memory die, and a dramatic 52.21% improvement in optimization iterations, achieving record-breaking efficiency for this complex industrial task. This demonstrates EvoStage's capability to deliver superior performance and efficiency in understudied, real-world scenarios.
