  • We are returning to a fully in person contest with a site structure similar to years before COVID. There will likely be accommodations for those schools that are unable to afford travel costs (we may be able to set such schools up as a micro-site like we did last March). We will follow ICPC rules for the North America Championship and World Finals for teams

  • Special thanks to our sponsors of this year's contest
    • Top Sponsor: F5
    • Medals and Plaques Sponsor: Jerry Cain
  • Feel free to email the contest at tcapaul@uw.edu with any questions, comments, or concerns that you have
• There will be medals this year, as there were with last year's contest. There will also be plaques. Medals and plaques are possible due to a generous donation from Jerry Cain of Stanford University. Jerry is a long time contributer to the PacNW region as a problem writer, judge, fund raiser, and coach. ICPC and the PacNW region sincerely thanks Jerry for all he has done for us! 
  • Medals and plaques will be allocated based on our traditional site model with Hawaii, California, Oregon, British Columbia, and Washington being single sites. There will be medals and plaques for both D1 and D2 as in past years.
    • More specifically, there will be Gold, Silver, and Bronze medals for first, second, and third place in
      • D1 overall
      • D2 overall
      • D1 at each site
      • D2 at each site
    • Each team member will get a medal
    • There will be one plaque per team and that will go to the coach and school
    • Medals and plaques will be mailed to coaches for distribution to team members
• There will be two divisions as in past years. D1 is the top division and teams can advance from D1 to the North America Championship (there will be no divisional championships as was done last year). D2 is for less experienced teams. When registering a team to compete in D2 be sure and place a D2 in front of the team name. For more information on divisions please see the information provided below.
• Division 1 (D1) is for teams that are VERY STRONG algorithmically.  The D1 problem set is difficult.  It is along the lines of a lite version of what you would see at World Finals.  Check the Results tab above and view D1 performance from years past.  Many teams have had a difficult time.  
  • Division II (D2) is approachable for teams that have not completed the algorithm sequence at their school and/or have not competed in programming contests before.  Almost all problems in D2 can be solved using techniques at the CS1 and CS2 levels.  Most teams in this division have a great chance at solving many problems.  If a team does well in this division this year, that team should try D1 next year!  Participating in D2 will not count against your eligibility for World Finals in future years (other than the rules established by ICPC itself based on age/year in school -- see the Contest Rules tab above for more information on the ICPC rules)  When registering a team for D2 on the ICPC registration site, include 'D2' at the beginning of the team name.  See the Registration tab above for more information.
• Important note: While it is technically possible to advance from D2, it is very difficult. All teams from D1 that solve at least one problem will be ranked higher than all teams that compete in D2.
• The following zip file contains three problems that serve as a baseline for competing in Division 1.  If a team cannot solve these three problems, that team should compete in Divsion 2.  The file contains input, output, and solutions to each problem along with a README that includes hints.  The file size is ~15MB.

• Check the two division FAQ for more details
• Pictures Page!
• We will once again support Python (as well as C, C++, and Java).  We will support Python 3, following what World Finals supports.  Please see the Details tab for more information.
• If you would like to be a future site host, please contact Tom Capaul tcapaul@uw.edu.  Costs of the contest (food, t-shirts, balloons, etc.) are covered by the PacNW region.  As a host school your teams participate for free.
