The paper introduces ARTEMIS, a no-code evolutionary optimization platform that automatically tunes large language model (LLM) agents by jointly optimizing prompts, tool descriptions, and parameters using semantically-aware genetic operators. Starting from a benchmark script and natural language goals, ARTEMIS discovers configurable components, extracts performance signals from execution logs, and evolves configurations without architectural changes. Experiments on four agent systems show significant gains: a 13.6% increase in acceptance rate for the ALE Agent, a 10.1% performance boost for the Mini‑SWE Agent, a 36.9% token‑reduction for the CrewAI Agent, and a 22% accuracy improvement for the MathTales‑Teacher Agent using a smaller open‑source model.

TGR‑EvoDAG is a DAG‑based multi‑agent framework that automates code evolution for generative recommendation systems, addressing cost blindness and short‑sighted evaluation issues in existing recursive self‑improvement methods. It incorporates stage‑aware cost planning and active downstream co‑adaptation to manage GPU‑hour budgets and navigate temporary regressions, enabling autonomous evolution of a complete generative recommendation pipeline. Experiments on Amazon datasets and deployment on Tencent’s media platform show significant offline metric gains and a measurable increase in online click‑through rate.
