June 2025 performance summary for Shubhamsaboo/llm4ad: Delivered core ReEvo toolkit and simulation integration with test scripts and repo cleanup, enabling automated algorithm design. Overhauled profiling and logging with WandB profiler and broader coverage across core methods, improving observability and debugging. Added local LLM backend support (Ollama and vLLM) to run in-process without cloud API, increasing flexibility and speed for development and testing. Implemented LLM resource cleanup to close resources after search to prevent leaks, improving reliability and resource usage. Demonstrated circle packing feature (26 circles in unit square) with data, verification, and visualization to validate layout algorithms. Performed targeted codebase maintenance (import refactor, updated ignore patterns, minor renames) to improve maintainability. These efforts collectively enhanced automation, observability, resource safety, and deployment flexibility, delivering measurable business value through faster iteration, reduced risk of leaks, and more robust tooling.
