April 6th, 2009Rafal Kasztelanic is our Early Bird WinnerBy popular vote, Rafal Kasztelanic’s submission, MATLAB Contest - creativity is the winner of our Early Bird award. His visualizations show the authors who contributed the most original lines of code to the contest. We welcome Rafal Kasztelanic, a new contributor to the File Exchange and a new inductee to the contest Hall of Fame. Pulling an equal number of votes, but submitted a couple hours later, is nathan’s meet the family, which tracks evolution and parentage using both code analysis and explicitly credit. Both of these entries remain in the running for the final prize, so follow them in the Rankings and cast your votes accordingly. April 3rd, 2009Early-Bird PrizeWe will award an Early Bird prize for the entry with the most votes on Monday at noon EDT. For this mid-contest prize, there well be no designated voting period, so entries submitted earlier will have the opportunity to attract more votes. As explained in the rules, you vote for an entry by tagging it “vis2009″. If you change your mind, simply remove your tag. All entries are listed on the Rankings page. Vote for as many entries as you’d like. April 2nd, 2009How to publish your codeWith this contest, one of the skills required to enter is the ability to publish code that was written in cell mode. The seventh video I ever made for my blog was on this subject. Take a look at this blog entry from 2006 to see how to publish your code. Remember to include the HTML directory in the .ZIP file that you submit as your entry into the contest.

April 1st, 2009We’re under way!The Spring 2009 MATLAB Programming Contest is under way. As we said, this contest is structured very differently from our usual contests. The complete rules are available here, but in a nutshell, this is an open-ended contest where you are the judge. We want you to look at one very interesting data set and see what kind of insights you can mine from it. The data set in question is one of the most interesting that I know of: the data from one of our previous contests, the Peg Solitaire contest that we ran in May of 2007. I’ve been looking at data from this and other contests for years now, and I’m constantly finding new stories buried in the data. And since many of you actually participated in that contest, you’ll be particularly well positioned to find the good stories hiding in there. As a side note, you will see a few MathWorkers like me contributing entries during this contest, but we’re not allowed to win any prizes. March 31st, 2009New contest starts tomorrowTomorrow we will be launching a new contest on data visualization. Its format will be very different from our other contests to date. Look for more information at noon tomorrow (12 PM EDT) when the contest opens. February 27th, 2009Army Ants Contest WinnersIn case you missed it we posted the Army Ants Contest Winners, along with a background and commentary of each. November 18th, 2008Commentary: all King vs. King pairings on actual boardsDoug has posted his commentary showing all possible pairings of the various Kings of the Hill. See which Kings held up best against all the others.November 14th, 2008Fabio C. Wins the Army Ants ContestThe entry processing machine is exhausted. It was a long haul. When the smoke cleared, Fabio C.’s entry was on the top, making him the winner of the Army Ants contest. He joins our other winners, listed in the Statistics, in the MATLAB Contest Hall of Fame. November 12th, 2008nathan q and Edin Win Daylight Rounds 3 and 4Congratulations to our two new winners, nathan q and Edin. Unless these are pseudonyms, they are two new inductees into the Hall of Fame. We’ve applied the patch suggested by Markus Buehren that will stop entries from failing when the King of the Hill errors. We’re in our final round and near the end of the contest. Good luck! November 10th, 2008New video commentary postedDoug has posted his video commentary showing the first five King Of The Hill entries running on the first three boards. Watch it here. November 9th, 2008Markus Wins the Saturday-Sunday RoundMarkus wins this round, followed by SY, pagangod, David Jones, and Nick Howe. You can now see the rankings for all previous rounds in the statistics. November 8th, 2008David Jones is our Friday-Saturday WinnerDavid Jones is our winner for the Friday-Saturday round and the new King of the Hill. David dominated our last contest, as recorded in the Hall of Fame, and it’s great to see him back. SY, Jan Langer, Alan Chalker, and the cyclist followed him in the rankings, contest heavyweights all. November 7th, 2008Contest video commentary: DarknessDoug has posted his commentary on the first King of the Hill. It is in video form on his regular Video tutorial blog. The first four boards are run and commented on. (Six minutes).
nathan q is the Twilight WinnerCongratulations to nathan q for winning the Twilight round. SY, Jan Langer, Abhisek Ukil, and Andreas Bonelli round-out the top five. We’re now in daylight, where everyone can see all the code, including King of the Hill. We now have our first round in Daylight, ending tomorrow at noon. We’ve been doing a lot of thinking about the timing details, largely based on feedback we’ve been getting in the newsgroup. We’ve decided to do one daylight round as-is. We’ve been experimenting with some alternative timing metrics based on your feedback, but aren’t yet sure what changes to make. This is a new format, so keep telling us how it’s working out for you. November 6th, 2008Jan Langer Wins DarknessThe queue was off to a slow start this morning, but results are now in for the Darkness phase. Jan Langer is our winner! A contest veteran, you can read about his previous contest experiences in the Hall of Fame. He’s followed in the rankings by Nick Howe, SY, Mila Naudé, and Benja&Litos. Jan’s entry, “ebi v1″, now becomes the opponent that all entries will be tested against until Twilight ends at noon tomorrow. His code will remain hidden, making Twilight especially tricky. Twilight BeginsWe’re now in Twilight, where you can see everyone’s scores but not their code. The queue is a bit backed up and will take a while more to clear. When we’ve scored all the entries submitted before the noon deadline, we’ll declare a winner, stop the queue, and make their entry the new King of the Hill. All entries submitted Thursday afternoon and before Daylight begins at noon on Friday will be scored against this new “house” ant. Slight Delay Entering TwilightWe’ll be showing the scores soon. We’ll announce the Twilight winner as soon as we finish processing all the entries submitted before noon. November 5th, 2008Army Ants is Up and RunningI couldn’t figure out why it wasn’t working, so I pulled the CAPCHA for now. The rules are up, so submit away. Darkness ends tomorrow at noon EST, when we award our first mid-contest prize and reveal everyone’s scores. The winner of Darkness will become the “king of the hill” in Twilight. Army Ants is Live… AlmostThe rules are up, but we’re having a bit of trouble with our spam filtering for entries. If it keeps saying your not entering the words correctly, don’t worry, you’re a human. I’ll spend a bit more time trying to debug this, or we’ll remove it completely. November 4th, 20082008 Fall Contest is less that 24 hours awayCan you believe it? It is almost that time again - almost time for our next contest! The contest masters have been hard at work, and as we speak are putting the finishing touches on this season’s challenge. So, right this minute, go into your calendar and schedule to check back tomorrow after noon Eastern time, to find out what’s in store…. See you all then! Helen and the MATLAB Central Contest team May 28th, 2008Yi Cao breaks 13000!Yi Cao loves a challenge. It took a few extra weeks worth of work, but Yi Cao is reporting in the newsgroup that he broke the 13000 barrier. You may recall that Alan Chalker had suggested such a thing might well be impossible. Yi Cao is just the sort of person to find out if it couldn’t be done. It could. Nice work! May 8th, 2008Actual Test Suites Added to File Exchange SubmissionSad to see the queue closed? Have one more idea to try out? Is there some analysis you’d like to perform? Download the updated File Exchange submission and try it yourself. Be sure to share any interesting results on the newsgroup. May 7th, 2008Stefan Rach is Our Contest WinnerStefan Rach is the Grand Prize winner for the Wiring Contest. Like usual, we had a flood of entries here at the end, but when the Wrapping up another contest, we’re happy to see all the great feedback coming in on the newsgroup thread. Please keep it coming. |
