I had to look up these acronyms:

- USAMO - United States of America Mathematical Olympiad

- IMO - International Mathematical Olympiad

- ICPC - International Collegiate Programming Contest

Relevant paper: https://arxiv.org/abs/2503.21934 - "Proof or Bluff? Evaluating LLMs on 2025 USA Math Olympiad" submitted 27th March 2025.
