Code-to-Harness: Distilling Black-Box Optimizers from Self-Play

The paper investigates whether an agent can learn a numerical search strategy through executable practice and then encode that strategy as text. By repeatedly writing and evaluating optimizer programs, the agent distills a 197‑word text called Harness A, which significantly reduces regret for Gemini Flash and other language‑model executors, matching the performance of classical Gaussian‑process Bayesian optimization. An independent replication produced a different but equally effective text, Harness B, and the framework also achieved the lowest regret on a sealed YouTube reward‑tuning benchmark.

Designing Reward Signals for Portable Query Generation: A Case Study in Industrial Semantic Job Search

arXiv:2606. 27291v1 Announce Type: new Abstract: Job-search platforms rely on low-bandwidth query interfaces that often fail to capture the high-dimensional complexity of candidate profiles.

Designing Reward Signals for Portable Query Generation: A Case Study in Industrial Semantic Job Search

Job-search platforms rely on low-bandwidth query interfaces that often fail to capture the high-dimensional complexity of candidate profiles. We present an end-to-end RLAIF (Reinforcement Learning from AI Feedback) framework to generate \emph{portable} job search queries, terms that abstract away seeker-specific identifiers while preserving generalizable qualifications.

HarnessOpt-Bench: Evaluating LLMs at Harness Optimization

arXiv:2608. 06301v1 Announce Type: new Abstract: As LLMs are increasingly deployed within agentic systems, their capabilities depend not only on the model weights but also on the harness: the prompts, tools, control flow, memory, and orchestration code surrounding them.
