Ask Before You Optimize: Dynamic Pre-Formulation Clarification for Interactive Optimization

Read the original on arXiv AI →

The paper introduces OR‑Clarify, a benchmark that tests whether large language models can identify missing elements in natural‑language optimization requests before formulating a mathematical model. Each task provides a partial problem description and hides structured slots; agents interact with a simulated user to recover these slots, with metrics for accuracy, stopping decisions, and interaction cost. The authors also propose InterOPT, a two‑stage framework that detects unresolved gaps and decides whether to ask further questions or stop, achieving superior slot recovery in choice‑based experiments and competitive performance in open‑ended settings.

CCTU: A Benchmark for Tool Use under Complex Constraints

CCTU is a new benchmark designed to evaluate large language models (LLMs) on their ability to use tools under complex constraints. It includes 200 test cases that average seven constraint types and 4,700‑token prompts, covering resource, behavior, toolset, and response dimensions. An executable validation module performs step‑level checks, and nine state‑of‑the‑art LLMs were tested, revealing that none exceed a 20% task completion rate when strict constraints are enforced, with frequent violations and limited self‑refinement.

Beyond Prompt Engineering: A Systematic Analysis of Prompt Lexical Sensitivity and Its Impacts on Quality

The paper investigates how small lexical changes in prompts can cause large performance swings in large language models. Using a dataset of 132,000 prompt variants, the authors uncover a scaling law linking higher average task performance to lower variance and greater robustness. They identify domain-specific terminology and explicit action directives as key linguistic factors that stabilize prompts, and propose an automated Prompt-Refining Agent that reduces performance variance by 40.7% in code generation while maintaining or improving mean performance.
