STAB: Specification-driven Testing for Algorithmic Bottlenecks

arXiv:2605.27981v1 Announce Type: new Abstract: Evaluating the efficiency of algorithmic code requires test cases that expose runtime bottlenecks. Previous methods generate efficiency test cases either by increasing input size or by generating code-specific inputs that make the given implementation run slowly. Consequently, they do not address the structural input conditions that drive the algorithmic worst case. We introduce STAB, a specification-driven pipeline that generates test cases that expose algorithmic bottlenecks from a natural-language problem specification alone. STAB separates th

Why this matters
Why now

The increasing complexity and scale of AI algorithms demand more sophisticated and automated methods for identifying computational bottlenecks to ensure efficiency and scalability.

Why it’s important

This development could significantly enhance the robustness and efficiency of AI agents and other complex software systems by automatically pinpointing performance issues, reducing development time and computational waste.

What changes

Algorithmic bottleneck identification, traditionally a manual and time-consuming process, can now be significantly automated directly from natural language specifications.
