बड़े भाषा मॉडल अधिक से अधिक प्रतिस्पर्धी प्रोग्रामिंग में उपयोग किए जाते हैं, और उनके आउटपुट विस्फोट के तरीके से संवेदनशील होते हैं। पहले काम में प्रतिस्पर्धी प्रोग्रामिंग पर सटीकता के लिए विस्फोट रणनीतियों की तुलना की गई है, लेकिन संचालित समय की गति के लिए नहीं, और परिणामों को मानव प्रदर्शन के विपरीत नहीं किया गया है। प्रत्येक नौ शैलियों में एक विस्फोट का एक सर्वेक्षण अध्ययन में, GPT-5.5 पर तीन सटीकता कार्यों के लिए कम से कम इन कार्यों के लिए, विस्फोट शैली को सार्वभौमिक के रूप में इलाज किए जाने के बजाय उद्देश्य के साथ मेल खाया जाना चाहिए, हमने पाया कि कोई भी विस्फोट सबसे अच्छा नहीं था: सबसे मजब

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 (IOI) and two NP-hard speed tasks, we found that no single prompt was best: the strongest prompt depended on the task type and on whether results were summarized by the mean or the median, suggesting that, at least for these tasks, prompt style should be matched to the objective rather than treated as universal. Many differences in mean scores came from a few outlier runs, showing that evaluating prompting by a single metric can obscure how much its effectiveness varies. Compared descriptively with human IOI contestants, who worked under different conditions, the AI was neither strictly better nor strictly worse, exceeding the average contestant on one task but falling short on the other two. By extending prompt comparison from accuracy to runtime speed and grounding it against human performance, this study gives a broader picture of how prompt style affects competitive programming performance.
