Internet Contests

Schedule

The USACO coaching team is proud to announce the schedule and format for the upcoming 2007-2008 pre-college programming contest season.
 

GOLD DIVISION:
The elite level with the most difficult challenges. The lowest-level competitors in this division should be able to create a dynamic programming algorithm from scratch (similar to the old Green division).

SILVER:
Just below the Gold division, Silver competitors should know a number of standard computer algorithms (e.g., the flood-fill algorithm). Silver is similar to the old Orange division.

BRONZE:

Students who can write programs that work, including ad hoc programs that don't require fancy optimized algorithms.

 

Our first contest will be the three (perhaps two) hour USACO
Qualification Exam.  Only those who wish to move up from their
current competition level need take this exam.  Its scores will be
used only for qualifying -- they will not be used for determination
of national champions, invitations to travel camps, etc. If you
wish, use it to expand your horizons with absolutely no penalties.
It is of slightly unusual format since it must cover multiple levels
of competitors.

The tasks and scoring are anticipated to facilitate placement of
competitors at the proper level. By no means will all competitors
will solve all problems. It is possible (after subsequent contests)
to be invited to move down a division if it is clear that the
contestant is misassigned.

Below is this year's schedule for this year's contests.

Contest lengths are not shown because we choose the length based
on the problems the contest contains.  Except for the US Open, which
is proctored and held on a single day for USA contestants, contests
run from Friday morning until Tuesday morning, USA Mountain Time:

 

Both Gold and Silver levels are "invitation-only".  Invitations are earned by:

  • Doing well on the October 19-22 qualification exam
  • Doing well at the Bronze or Silver Level on subsequent contests
  • Special cases as determined by the coaches
  • Achieving the Gold/Silver level in previous contests
     

Our first contest will be the three hour USACO Qualification Exam. Only those who wish to move up from their current competition level need take this exam.  Its scores will be used only for qualifying -- they will not be used for determination of national champions, invitations to travel camps, etc.

The tasks and scoring are anticipated to facilitate placement of competitors at the proper level. Not all competitors will solve all problems. It is possible (after subsequent contests) to be invited to move down a division if it is clear that the contestant is miss assigned.
 


  • Oct. 19-22, 2007 : (Optional)

Criteria For 2008
We will use all contest results and work on the training materials as evaluation criteria for choosing attendees at the USACO training camp to be held in June, 2008. 
.
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  progress on the training materials.
