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.

Contents

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]
