Idea First, Code Later: Disentangling Problem Solving from Code Generation in Evaluating LLMs for Competitive Programming (2026.findings-acl)

Copied to clipboard

Challenge: Existing evaluations conflate algorithmic reasoning with code-level implementation.
Approach: They propose to center editorials in both solution generation and evaluation . they propose to compare editorials to gold standards and validate an LLM-as-a-judge protocol .
Outcome: The proposed approach improves solve rates on some LLMs with gold editorials . but the gap between gold and generated editorials shows bottlenecks in implementation .
