This approach seeks to make the task of  whoever is               trying to affect the election <em>computationally<\/em> prohibitive.               To better understand the cases in which such protection  cannot be               achieved, researchers in this area also spend much of  their time               working for the Dark Side: trying to build polynomial-time               algorithms to attack election systems.<\/p><\/blockquote>\n<p>I have a particular fondness for this issue, since the 28 year old me (and his coauthors) wrote about this:<\/p>\n<blockquote><p>This complexity-based approach to protecting elections was               pioneered in a stunning set of papers, about two decades  ago, by               Bartholdi, Orlin, Tovey, and               Trick.\u00a0 The intellectual fire they lit smoldered for quite a  while, but               in recent years has burst into open flame.<\/p><\/blockquote>\n<p>Wow!\u00a0 Now that is a paragraph to send off to my Dean!\u00a0 <a href=\"http:\/\/mat.tepper.cmu.edu\/blog\/?p=920\">I have written<\/a> about how this approach was ignored for a long while, but is now pretty popular.\u00a0 It is great to see this coverage in an outlet like <em>CACM.<\/em><\/p>\n<p>The article goes on to survey this area, and has lots of nice things to say about those 20 year old papers (&#8220;seminal&#8221; (twice!), &#8220;striking insight&#8221;).\u00a0 And it makes a great case for all the work that has been done since, and issues going forward.\u00a0 Thanks Piotr, Edith, and Lane:\u00a0 I enjoyed the survey very much.\u00a0 And my Dad is visiting, and he too loved reading about what my coauthors and I had done.<\/p>\n<p>From the 50 year old me to the 28 year old me:\u00a0 &#8220;That was pretty good work!&#8221;\u00a0 And, if I can speak for the 28 year old me:\u00a0 &#8220;Thanks!\u00a0 What are you doing now?&#8221; 50 year old me: &#8220;Hmmm&#8230;.. can I tell you about <a href=\"http:\/\/mat.tepper.cmu.edu\/blog\/?p=623\">sports scheduling<\/a>? <a href=\"http:\/\/mat.tepper.cmu.edu\/blog\">Blogging?<\/a> Or perhaps I should introduce you to <a href=\"http:\/\/alexandertrick.blogspot.com\/\">Alexander<\/a>?&#8221;.\u00a0 28 year old me: &#8220;Wasn&#8217;t I the one who met Ilona, with whom you have Alexander?&#8221;\u00a0 50 year old me: &#8220;OK, we&#8217;ll split that one!&#8221;<\/p>\n<p>Different phases, different measures.\u00a0 But I am impressed with the 28 year old me every time I run across him.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>In the wake of coming across my network and matching notes, where the 28 year old me taught the 50 year old me some things I never realized I knew, in a way that leaves (the 50 year old) me breathless (at least about the amount of time the 28 year old me had), I &hellip; <a href=\"https:\/\/mat.tepper.cmu.edu\/blog\/index.php\/2010\/11\/23\/continuing-to-be-impressed-with-the-28-year-old-me\/\" class=\"more-link\">Continue reading<span class=\"screen-reader-text\"> &#8220;Continuing to be impressed with the 28 year old me&#8221;<\/span><\/a><\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[41,57],"tags":[],"class_list":["post-1290","post","type-post","status-publish","format-standard","hentry","category-personal","category-voting"],"jetpack_featured_media_url":"","_links":{"self":[{"href":"https:\/\/mat.tepper.cmu.edu\/blog\/index.php\/wp-json\/wp\/v2\/posts\/1290","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/mat.tepper.cmu.edu\/blog\/index.php\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/mat.tepper.cmu.edu\/blog\/index.php\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/mat.tepper.cmu.edu\/blog\/index.php\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/mat.tepper.cmu.edu\/blog\/index.php\/wp-json\/wp\/v2\/comments?post=1290"}],"version-history":[{"count":0,"href":"https:\/\/mat.tepper.cmu.edu\/blog\/index.php\/wp-json\/wp\/v2\/posts\/1290\/revisions"}],"wp:attachment":[{"href":"https:\/\/mat.tepper.cmu.edu\/blog\/index.php\/wp-json\/wp\/v2\/media?parent=1290"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/mat.tepper.cmu.edu\/blog\/index.php\/wp-json\/wp\/v2\/categories?post=1290"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/mat.tepper.cmu.edu\/blog\/index.php\/wp-json\/wp\/v2\/tags?post=1290"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
