This year the USACO will conduct three Internet-hosted contests, the U S Open, and the summer training camp and Finals.

Also, teams from the United States will attend the Balkan Olympiad in Informatics (BOI) in May, the Central European Olympiad in Informatics (CEOI) in August, and the International Olympiad in Informatics (IOI) in September.

Internet Contests


Continuing the highly successful Internet competitions, the USACO is holding three Internet contests (Fall, Winter, and Spring) to foster competition, recognize outstanding performance, and increase the level of expertise of pre-college programmers.

The Internet competitions have different formats: varying numbers and types of problems, varying time limits, and even varied entrance criteria. Most of the contests, though, emphasize individual competition and programming (vs. team contests popular in other venues). Each contest has two divisions; National, and International.

  • Nov 16-23, 1999 :
    The USACO Fall US Open. It is open to all pre-college students who have Internet access.
  • January 26-Feb 2, 2000 :
    The USACO Winter Tournament is open to all pre-college students who have access to the Internet.
  • March 8-15, 2000 :
    The USACO Spring Open is open to all pre-college students who have access to the Internet.

Rob Kolstad, has created a Challenge-of-the-Week (COW) for high school students interested in solving computer programming problems. It is maintained via e-mail at hs-computing@delos.com Send a message to: majordomo@delos.com. Include the text "subscribe hs-computing" in the body of the message. This is a wonderful opportunity for those seriously interested in making the final round of the USACO.

U S Open


The USACO U S Open is a five-hour proctored competition that is conducted at local high schools under the direction of a local coordinator. A 2000 USACO U S Open and International Champion will be crowned.

Criteria For 2000
We will use all contest results and many problem submissions as evaluation criteria for choosing attendees at the USACO training camp to be held in June, 2000. This means that candidates who show long-term strength (and/or growth) are more likely to be chosen for camp than those who have one lucky contest.
We will be keeping a record of all submissions for the challenge of the week and will be asking some of you to write up your solution and its techniques to share with the `aces' on our list. To that end, we'll be trying to grade some of the weekly problems. Presume it will take a couple weeks. we'll announce those who do exceptionally well
