1998 Tournament Results
Errata
Unfortunately we're not perfect, so there were a few small mistakes. Fortunately, none of them affected any of the results because they were all caught in the grading room. Here are a few corrections:
[Note: awards given at the awards ceremony are final.]
- Power Question Part IIIb. should read chi + chi bar >= 2*sqrt(v), not chi * chi bar. For a counterexample consider the graph with v = 1. Note that the incorrect statement holds if v >= 4. The solution given is for the corrected version of the problem; the question was actually graded on a 4 point scale with 4 points given for finding a counterexample.
- The national results read at the awards ceremony did not include the complete results from the other sites (the lists above are complete). Some local ties were broken by a slightly different algorithm than that used for the national rankings.
