Topcoder Open (TCO) was an annual design, software development, data science and competitive programming championship organized by Topcoder, and hosted in different venues around the United States.[1][2][3] In the first two years, 2001 and 2002, the tournament was titled TopCoder Invitational.
In addition to the main championship, from 2001 to 2007, Topcoder organized an annual TopCoder Collegiate Challenge tournament, for college students only.[4][5] The TopCoder High School competition was held from 2007 to 2010.
From 2015, Topcoder Regional events were held through the year in different countries.[6]
In 2020–2023, in-person Topcoder Open finals were cancelled and replaced by virtual events due to the impact of the COVID-19 pandemic and the subsequent economic slowdown. The 2023 Topcoder Open was the final edition of the contest.[7]
Competition tracks
[edit]Competition tracks included in the Topcoder Open tournament changed through its history. Many of them resemble the types of challenges offered to Topcoder Community through the year, but there is no 1:1 match. Here is the alphabetical list of all competition tracks ever present at TCO:
Algorithm Competition (SRM)
[edit]Timeline: 2001 – 2022
Champions: Gennady Korotkevich tourist (2022, 2021, 2020, 2019, 2014);
Petr Mitrichev Petr (2018, 2015, 2013, 2006);
Yuhao Du xudyh (2017);
Makoto Soejima rng_58 (2016, 2011, 2010);

Jan Kuipers Jan_Kuipers (2007);
Eryk Kopczyński Eryx (2005);
John Dethridge John Dethridge (2002);
jonmac (2001).
Details:
This was the only track that was present at all main TCO events and at most of the other Topcoder events. It followed the format of regular 1.5 hours Single Round Matches:[8]
- The Coding Phase – 75 mins: All competitors were presented with the same three algorithmic problems of differing complexity. Each problem had its own maximal number of points. Problem descriptions were initially invisible. Competitors had 75 minutes to solve these problems. A competitor could open any problem description in any order; once they opened a problem, the number of points they could get for the correct solution of that problem started decreasing over time. When the competitor submitted the problem solution—a code that successfully compiles—they were awarded with the current number of points they could get for that problem. They could re-submit a solution, getting the further decrease number of points, minus extra penalty for the resubmission. During this coding phase, competitors could see the current points awarded to each participant, but they could not see whether the solutions of those participants were correct or incorrect, including whether these scores would hold after The System Testing Phase or if they would be reset.
- The Challenge Phase – 15 mins: Each competitor could see all submissions completed by the other competitors. They could optionally challenge any of them by submitting test cases that would cause other competitor's submission to produce an incorrect result. Submission of a correct challenge test case gave the submitter a 50 points award, but submission of an incorrect test case (i.e. the challenged solution can solve it successfully) would lead to 25 points penalty for the test case submitter.
- The System Testing Phase – In the last phase, system tests were automatically executed for all of the submissions from all competitors. If a submission failed testing, the scores awarded for that submission during The Coding Phase were reset to zero. The final scores after the system testing determined the winner.

Competitors were provided with a set of small programming tasks, such as bug fixes or enhancements in an existing codebase, and they received scores based on who correctly solved each task first. The exact rules for on-site competition varied from year to year.

Competitors were provided with the same algorithmic or data science problem, which was judged objectively with a live leaderboard which was visible to everyone. Each competitor could submit multiple times with no penalties, with the goal to submit a code that scores the maximal possible amount of scores on that problem. During the competition, the leaderboard was generated based on submissions testing against a limited number of test cases, and, after the contest, the final results were determined with testing against a larger test dataset.
