How Prompt Style Affects AI Accuracy and Speed in Competitive Programming

View original on arxiv.org

Overview

arXiv:2610.30223v1 Announce Type: new Abstract: Large language models are increasingly used in competitive programming, and their outputs are sensitive to how a prompt is phrased. Prior work has compared prompt strategies for accuracy on competitive programming, but not for runtime speed, and has not situated the results against human performance. In an exploratory study of one prompt in each of nine styles on GPT-5.5 across three accuracy tasks from the International Olympiad in Informatics (IO
