Thanks to all of you who took part in round 3, new and returning competitors alike! This round proved to be a bit rougher than usual, both on your end and ours. To start, there were no perfect scorers in either division. Although the first three problems of both divisions had many wonderful full and partial solutions, the last problems seemed to have perplexed everybody. Indeed, getting 100% on either of them them required a fair bit of tricky preprocessing. On the other hand, we also did run into some issues with the problem statements and test data. The issues have all been addressed in comments to the corresponding problems on the judge. Although we strongly believe that these issues had a negligible effect on the overall results, we nonetheless promise to be more careful in the future.

The senior division prizewinners for this round are:
  • Timothy Li of Don Mills Collegiate Institute ($200)
  • Jeffrey Xiao of University of Toronto Schools ($100)
  • Jason Yuen of Pierre Elliott Trudeau High School ($50)
  • Bill Zheng of Richmond Green Secondary School ($50)
  • Weiwei Zhong of Glenforest Secondary School ($50)
The junior division prizewinners for this round are:
  • Jonathan Chang of Don Mills Collegiate Institute ($50)
  • Allan Xu of Woburn Collegiate Institute ($25)
  • Christopher DeGuzman of Glenforest Secondary School ($25)
Congratulations to all of you! These prizes will be distributed as Visa gift cards, and we will be contacting your teachers shortly about sending them out. If you haven't won a prize, keep on practicing! We have many more prize opportunities for you throughout the year.

A word on sockpuppets

Sockpuppeting is not an acceptable practice. Creating new accounts for the sole purpose of voting posts up or down is not permitted. When there were only one or two, that wasn't a big deal. But this is ridiculous, guys. I found about 20 sockpuppet accounts today.

Moving forward, I'll be deleting any sockpuppet accounts I find. We are able to link sockpuppets to main accounts. Be warned: your main account may suffer sanctions, including temporary or permanent bans from the site.

Thank to all of you who took part in round 2, new and returning competitors alike! Problems, solutions, and test data are now available in the "Past Contests" section of this site. With our experience from the previous contest, we’ve rounded out the edges to make this one much smoother for everyone involved. We hope you enjoyed the Star Wars themed storylines that were prepared in tribute to the imminent release of The Force Awakens. While the plot of the film remains to be unveiled, we dare say that we’ve at least tried our hands at some bold forecasting in problems J4 and S4.

----------------------------------------------------

From the mid-1990s to the early 2000s, the Woburn Challenge was an annual computer programming competition hosted and run by Woburn C.I.'s Programming Enrichment Group. We feel that the time is right to relaunch this free and fun competition for aspiring computer science students in Canada. This year, we're prepared to give out thousands of dollars in prizes to top-performing primary and secondary school students in Canada. If you are a Canadian primary or secondary school student (grades 1-12), you must follow the registration instructions at woburnchallenge.com/register to be officially eligible for prizes. While only this group of people can receive prizes, everyone is welcome to participate in the online rounds as observers.

This year, we're hosting 4 online rounds (each with a prize pool of over $500) and an in-person invitational finals at the end of the school year (even larger prizes to be announced!). The rounds will take place in October, December, February, April, and early June (for the finals).

Online Round 1

When: Friday, October 16th, 2015 from 3:30 pm to 6:30 pm ET
Where: The PEG Judge interface (wcipeg.com/contests)

Prizes:
  • Top 3 Junior division winners: $50, $25, $25
