Revision en1, by cjj490168650, 2023-04-10 07:47:32

Translated by GPT-4 with some adjustment. Original post: 「正义可以迟来但不能缺席」:关于 NXIST 的一些新证据

This article provides a logically complete set of evidence, which does not involve any non-public internet resources, regarding the "suspected cheating" incident involving the ICPC Yinchuan Station and ICPC Shenyang Station in 2021. By discovering the suspected GitHub account (NaokiLH, renamed to [](https://github.com/brokenTarget)) of a team member from Ningxia Institute of Science and Technology (NXIST) TS 1 team, Lan Hao, two years ago (), and by mining and analyzing the commit records of his algorithm competition repo, we have obtained direct evidence that at least 4 questions from the 2021 Yinchuan regional contest set and at least 6 questions (including scrapped questions) from the 2021 Shenyang regional contest set were leaked to him at least one week before the competition. The substantial amount of new public evidence indicates that the TS 1 team indeed cheated, and the relevant students were heavily involved.

This is the first direct evidence related to the incident after several years of discussion. This article is based on the mining and analysis of publicly available online information by @lucas110550 and @曾耀辉, and all the evidence provided does not involve any infringement or violation of relevant regulations. At the same time, @陈靖邦 conducted overall coordination and review. We welcome everyone to report and supervise.

Considering that the vast majority of the evidence comes from the commit history of the suspected NaokiLH (Lan Hao)'s GitHub repo, to prevent the person involved from deleting and fleeing after this article is published, we strongly suggest everyone fork the corresponding repo to permanently keep this record.
