Looking at all the boards, they were actually fairly close on many of entries:\r\n<p>\r\n<img src='https:\/\/blogs.mathworks.com\/videos\/..\/images\/videos\/2009\/11\/contestdifference.jpg' alt='contestdifference.jpg' \/>\r\n<p>\r\n\r\n\r\n\r\n<p>\r\nHowever, we can see that on some of the boards, the winning entry did significantly better.  The boards that it won on were those with the large valued 80&#8217;s randomly around the board.\r\n<p>\r\n<img src='https:\/\/blogs.mathworks.com\/videos\/..\/images\/videos\/2009\/11\/contestfinalbetter.jpg' alt='contestfinalbetter.jpg' \/>\r\n<p>\r\n\r\nSurprising to me, the 1000 node solver did noticably better on a couple of the tall skinny boards like this:\r\n<p>\r\n<img src='https:\/\/blogs.mathworks.com\/videos\/..\/images\/videos\/2009\/11\/contest1000beter.jpg' alt='contest1000beter.jpg' \/>\r\n<p>\r\n\r\nThat leaves me wondering if someone could have done a quick check to see if the board had 30 colors or so, and then tried the simpler solver.  It looks like this would have made some significant gains&#8230;\r\n\r\nA good contest, congratulations to all that participated.","protected":false},"excerpt":{"rendered":"<div class=\"thumbnail thumbnail_asset asset_overlay video\"><a href=\"https:\/\/blogs.mathworks.com\/videos\/2009\/11\/13\/contest-flood-wrap-up\/?dir=autoplay\"><img decoding=\"async\" src=\"https:\/\/cf-images.us-east-1.prod.boltdns.net\/v1\/static\/62009828001\/bc1e16ad-ad48-4553-9c16-c66f921ae4fe\/2d367773-c05d-4972-8552-c707c454cefd\/160x90\/match\/image.jpg\" onError=\"this.style.display ='none';\"\/>\n      <div class=\"overlay_container\">\n      <span class=\"icon-video icon_color_null\"><time class=\"video_length\">9:20<\/time><\/span>\n      <\/div>\n      <\/a><\/div><p>Here is the wrap up of the MATLAB programming contest that we just ran.\r\n\r\nif (typeof(playerLoaded) === &#8216;undefined&#8217;) {var playerLoaded = false;}(function isVideojsDefined() {if (typeof(videojs) !==&#8230; <a class=\"read-more\" href=\"https:\/\/blogs.mathworks.com\/videos\/2009\/11\/13\/contest-flood-wrap-up\/\">read more >><\/a><\/p>","protected":false},"author":68,"featured_media":0,"comment_status":"open","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":[],"categories":[4,12,10],"tags":[],"_links":{"self":[{"href":"https:\/\/blogs.mathworks.com\/videos\/wp-json\/wp\/v2\/posts\/409"}],"collection":[{"href":"https:\/\/blogs.mathworks.com\/videos\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/blogs.mathworks.com\/videos\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/blogs.mathworks.com\/videos\/wp-json\/wp\/v2\/users\/68"}],"replies":[{"embeddable":true,"href":"https:\/\/blogs.mathworks.com\/videos\/wp-json\/wp\/v2\/comments?post=409"}],"version-history":[{"count":1,"href":"https:\/\/blogs.mathworks.com\/videos\/wp-json\/wp\/v2\/posts\/409\/revisions"}],"predecessor-version":[{"id":2663,"href":"https:\/\/blogs.mathworks.com\/videos\/wp-json\/wp\/v2\/posts\/409\/revisions\/2663"}],"wp:attachment":[{"href":"https:\/\/blogs.mathworks.com\/videos\/wp-json\/wp\/v2\/media?parent=409"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/blogs.mathworks.com\/videos\/wp-json\/wp\/v2\/categories?post=409"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/blogs.mathworks.com\/videos\/wp-json\/wp\/v2\/tags?post=409"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
