About
'CATArena: Evaluating Evolutionary Capabilities of Code Agents via Iterative Tournaments' (Fu et al.), arXiv 2510.26852 (v1 30 Oct 2025, v2 30 Jan 2026), published in the Proceedings of the 43rd International Conference on Machine Learning (PMLR 306, pp. 31726–31755, 2026). Agents compete in multi-turn tournaments and are scored with a dual-metric system separating static coding skill from evolutionary potential.
