2020 USACO February Contest -- Final Results

The 2020 USACO February contest featured algorithmic programming problems covering a wide range of techniques and levels of difficulty.

We love the energy and spirit you bring to the world’s biggest and best strongman competition, but we feel this is the safest decision for our fans, competitors, staff and the local community. We are working on ways to provide live behind-the-scenes access that can be enjoyed from home for the first time, so stay tuned for an exciting update. We plan to make only a minor adjustment to our $22 fair value estimate for no-moat Bed Bath & Beyond after digesting third-quarter results. Sales of $2.76 billion were modestly ahead of the $2.7.

A total of 5799 distinct users logged into the contest during its 4-day span. A total of 4976 participants submitted at least one solution, hailing from 76 different countries:

• I compete regularly in Smallbore Prone competition. I am by NO means a top level competitor. However, shooting on the 100 yard NRA target with its 1' X ring and 2' 10 ring, it is not uncommon for me to score 400 / 25 35 X, nor is it uncommon for my fellow competitors to do so as well. Anschutz 1413 and Lapua Center X or Midas + ammo.
• The 7-300 WSM has slightly different chamber dimensions than a 7 WSM. Robert Whitley explains, “The difference is that the 7mm/300WSM has a.038″ shorter head space and a.038″ longer neck than a factory 7mm WSM, and you need to make brass for the 7mm/300 WSM from 300 WSM or 270 WSM cases.” (Read more here).
• The 2019-2020 season is winding down - just one more contest to go before we name our next set of finalists. I'm quite happy that this contest ran quite smoothly, particularly since it was the first being run on a new server. Performance as a whole was quite impressive despite challenging problems at all levels of the contest.

In total, there were 13498 graded submissions, broken down by language as follows:

Final Remarks

The 2019-2020 season is winding down --- just one more contest togo before we name our next set of finalists. I'm quite happy thatthis contest ran quite smoothly, particularly since it was the firstbeing run on a new server. Performance as a whole was quiteimpressive despite challenging problems at all levels of the contest.

I would remind our competitors that creation of duplicate accounts andother forms of abuse of the contest system (which unfortunately seemto be on rise, especially from overseas) are not tolerated and willresult in lifetime disqualification from USACO participation (sortingout these issues is perhaps also the primary reason slowing downgeneration of contest results).

For those not yet promoted,remember that the more practice you get, the betteryour algorithmic coding skills will become -- please keep at it! USACO contests are designed to challenge even the verybest students, and it can take a good deal of hard workto excel at them. To help you fix any bugs in your code, youcan now re-submit your solutions and get feedback from thejudging server using 'analysis mode'.

A large number of people contribute towards the qualityand success of USACO contests. Those who helped with thiscontest include Mark Gordon, Benjamin Qi, Jonathan Paulson, Spencer Compton, Travis Hance, Dhruv Rohatgi, and Nick Wu.Thanksalso to our translators and to Clemson CCIT for providing our contest infrastructure. Finally, we are grateful to the USACO sponsors for their generous support: TwoSigma, D.E. Shaw, and Ansatz Trading.

We look forward to seeing everyone again for the US Open contest, our national championship.

Happy coding!
