Final Standings

2024/09/12

A total of 77 teams have been disqualified from this contest. All these teams submitted suspicious codes during the contest. The disqualified teams can be categorized into three groups:

1. Coaches were present during the competition. But upon being presented with evidence of the teams’ cheating by the Contest Director, the coaches acknowledged the teams’ misconduct and agreed that they should be disqualified.
2. Teams were unable to provide the requested screen recordings by the deadline.
3. The submitted screen recordings were either less than three hours in length or showed clear signs of editing, indicating attempts to conceal inappropriate behavior.

2024/09/08

We regret to announce that codes submitted from some teams were found to be either copied from each other or similar to codes generated by generative AI. Investigations and confirmations will take some time, and the final results of the contest are expected to be announced by September 14, 2024.

We have updated the information about the contest environment.

Scoring & Ranking

• 計分與排名 Scoring & Ranking
  隊伍以解題數量多者排名較前，解題數量相同時，以總消耗時間少者排名較前。 答對的題目的消耗時間計算方式為比賽開始至解出題目所消耗的分鐘數。 如解出前有答錯，除編譯錯誤之外，每答錯一次需要另加 20 分鐘。 總消耗時間為所有答對題目的消耗時間加總。未答對的題目不計消耗時間。
  Teams are ranked according to the most problems solved. Teams who solve the same number of problems are ranked by least total time. The total time is the sum of the time consumed for each problem solved. The time consumed for a solved problem is the time elapsed from the beginning of the contest to the submittal of the accepted run plus 20 penalty minutes for every rejected run for that problem that was not rejected due to Compilation Error. There is no time consumed for a problem that is not solved.

• 平手判定 Tie-Breaker
  解題數與消耗時間均相同時，以先答對最後一題者獲勝。
  If multiple teams have the same number of problems solved and total time, then the winner goes to the team which first submitted their last accepted solution.
