Online Computer Programming Contest

Round 4 Summary by Cyril Zhang

Post-mortem is an apt description for this post, just as "death" basically summarizes this contest.

In any case, congratulations to Fan Zhang and Geoffry Song (Team * Star *, Lisgar CI) on prevailing, and being the only team to solve the fourth problem! Daniel Hui (Woburn CI) took an early, commanding lead, and finished in second place. For third place, there was a tie between Hanchen Wang, Peter Chen, Scott Hall, and Austin Chiang (Team FOUR AWESOME DUDES WHO USE THAAAAA POOOOWWWWWAAAAAA OF PENCIL AND PAPER! :D, Earl Haig CI), and Sirui Shen and Kevin Rupasinghe (Team Sirui, Vincent Massey).

If you're not already shell-shocked, you might want to take a look at the solutions to today's problems (http://compsci.ca/v3/viewtopic.php?t=30659), because I have a feeling that you'll see some of these topics in the very near future. Pay special attention to the DP on subsets to #4. You'll find that the embedding used in #5 appears in many natural Manhattan distance problems, so please take a look at that too. Contest season is fast approaching, and there is no such thing as too much computer science.

Hope you enjoyed the round. Until next time! :)

Today is the third round of the 2011-2012 DWITE contest. We have added the D programming language to the judge and their are 258 teams signed up to take the contest today. Make sure to check out the the judge page to see how your language will be complied.

Good luck and have fun.

Round 2 and Judge Updates by Dan

Today is the second round of the 2011-2012 DWITE contest which brings with it some updates to the judge:

The following languages have been updated to their newest version:

• Java
• C
• C++
• Visual C++
• Visual C#
• Visual Basic
• Perl
• Lisp
• Ruby

The following languages have been added:

• Fortran
• OpenTuring

Other changes:

• All languages previously using cygwin are now using MinGW
• Turing now has a more reliable and faster launcher
• Line break issue from last round should be fixed by switching to MinGW

Please visit http://dwite.ca/judge for full details on which version of each language is being used and how it will be run by the judge. Turing users may wish to consider using OpenTuring which maybe faster in some cases but is still experimental.

Round 1 Summary by Tony

Other than leaving an ambiguity in Q5's spec and having Q4 turn out to be easier than intended, this was probably our best round yet. All of the test data was correct, and there were minimal technical difficulties during the round.

We'd like to congratulate Gary Zeng (team PropagandaPanda from Don Mills Collegiate Institute) for taking first place, Daniel Hui (team d310 from Woburn Collegiate Institute) and team * Star *(Fan Zhang and Geoffry Song) in tie for a second. Well done!

A.J. and Cyril have been discussing this Round's solutions on the forums -- check it out.

As well, we got a few requests for making upgrades to some programming languages used. We'll be working on that. As a reminder, feel free to contact us via http://dwite.ca/contact and forums.

As a bonus, here are some interesting stats from the first round:

Today is the first round of the 2011-2012 DWITE season. We have 233 teams signed up to take the contest with a total of 506 students.

This will also be one of the first rounds with Cyril (of past DWITE fame) helping with the questions along side Tony and AJ.

Good luck and have fun!
