Round 4 Summary

Thu, 19 Jan 2012 07:27:42 -0500

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! :)

3rd Round

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

Wed, 30 Nov 2011 10:48:50 -0500

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

Sat, 29 Oct 2011 20:13:56 -0400

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:

Round One Today

Wed, 26 Oct 2011 12:11:57 -0400

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!

Introducing 2011-2012 Season

Mon, 26 Sep 2011 22:35:53 -0400

We've just published the dates for all 5 Rounds of DWITE's 2011-2012 Season. You can now begin registering and signing up for participation.

AJ has already started designing the questions. With such a head start, we should have top quality content available.

As well, we might be getting Cyril Zhang (of the rocks DWITE's socks fame -- see previous news posts) to help out with running things this Season. At the very least he'll be an extra expert to make sense of questions and test data. But with extra contributors, we might come up with something new for this Season as well. Stay tuned!

CS4HS Mini Programming Contest

Tue, 12 Jul 2011 16:26:40 -0400

We'd love to hear any feedback or comments that you might have about DWITE as a platform for programming contests. You could join the discussion at http://dwite.uservoice.com or contact Tony and Dan privately through http://dwite.ca/contact.

That's it for the 2010-2011 Season

Wed, 23 Feb 2011 18:47:13 -0500

As AJ has so nicely put it the morning before the final round of this season:

DWITE today! Good luck with this round...you'll need it ;)

The difficulty was certainly turned up, and there were plenty of 0/5 and 1/5 scores even from the top 10 teams. 145 teams participated this round, 133 teams received non-zero scores. Cyril Zhang (of team Cyril; Don Mills Collegiate Institute), Mike Seo (of team MikeS; W L Mackenzie CI), and Kevin Yeo (of team KYeo; also W L Mackenzie CI) secured the top 3 spots this round. Congrads.

Cyril ninja~ed that win, with a late start:

Late for round 5 due to music competition. ~_~

You, sir, are ridiculous. I'm impressed, and a little bit scared.

That's it for the season!. CCC is less than a week away (March 1st, 2011), and ECOO is shortly after. Hopefully DWITE has made you more prepared to take on those competitions.

Just in case we don't have enough of those feedback links plastered all over the front page today, here it is again! http://dwite.uservoice.com/ It's quite important for us to hear back from you, about anything. Do you think we should have more questions about bacon? Sure, whatever. Make that suggestion and vote it up to the very top. We'll be looking at this to make changes and taking on new projects for the next season.

Feedback

Wed, 23 Feb 2011 06:31:52 -0500

This is the last round of the season, and we'd love to hear how we did! We've setup a feedback forum to talk about question difficulties, future contests, and new projects for our team to take on (is anything a pain in the process of teaching CS?). But the best part is that the forum is open for new topics/suggestions from everyone. Provide and comment on ideas/feedback, or at the very least vote on what topics are important.

Feedback forum is available at http://dwite.uservoice.com/

Last Round of 2010-2011

Wed, 23 Feb 2011 06:30:00 -0500

Today is our last round of the season and we have 219 teams signed up to participate so far. Remember to leave us some feedback at http://dwite.uservoice.com/ so we can improve the contest for next school year.

Good luck and have fun!
