Like, Nash theorem is just application of kakatuni's fix point theorem. Credit goes for the modelling so that it is easy to prove and really works.I am what I amhttps://www.blogger.com/profile/10632729623999295377noreply@blogger.comtag:blogger.com,1999:blog-3722233.post-1161097934222075342006-10-17T10:12:00.000-05:002006-10-17T10:12:00.000-05:00I am a famous complexity theorist and I approve th...I am a famous complexity theorist and I approve the previous message.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-3722233.post-1161062133385786772006-10-17T00:15:00.000-05:002006-10-17T00:15:00.000-05:00To anonymous:As Lance said "Andrew Yao observed......To anonymous:<BR/><BR/>As Lance said "Andrew Yao observed..."<BR/><BR/>Even though the result is trivial to prove, it is amazingly important and useful.<BR/><BR/>I believe this is why Yao gets so much credit for it.<BR/><BR/>(I am just a student.

What I never understood was, is this -really- more than an application of Von Neumann's minimax theorem? It seems like a corollary od Von Neumman's theorem, that gets huge amounts of credit.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-3722233.post-1161040419968589872006-10-16T18:13:00.000-05:002006-10-16T18:13:00.000-05:00One of my favorite as well.

I would add that this is very easy to use: instead of finding a single worst case (say, for a fixed size of input), you just have to find a bunch of those "worst cases", forming a distribution large enough that no algorithm can take advantage of it. Typically, taking all the instances which are the worst case of some deterministic algorithm...dothttps://www.blogger.com/profile/14825435867493579983noreply@blogger.com
