Each Jim row, when read in binary (yellow = 1, red = 0) is the number of teddy bears in the corresponding NIm pile.<br /><br />The Jim strategy is easy (easier?) to understand - it's just a parity argument on the number of yellow chips in each column. I decided that understanding that strategy first, before linking Nim to its binary representation, was the way to go.<br /><br />This still begs the question - why does Nim have this binary strategy? So, while I don't feel like I've shed much light on this question, I'm happy with the sequencing of explaining Nim strategy.The Math Wizardhttps://www.blogger.com/profile/17314060401914172768noreply@blogger.comtag:blogger.com,1999:blog-7269643900637972693.post-11621744095062715352011-04-22T13:19:57.686-04:002011-04-22T13:19:57.686-04:00If I'm understanding the rules of Jim right, t...If I'm understanding the rules of Jim right, then they are actually isomorphic games, yes?benblumsmithhttp://researchinpractice.wordpress.com/noreply@blogger.comtag:blogger.com,1999:blog-7269643900637972693.post-32523596284311223622011-04-22T12:49:28.809-04:002011-04-22T12:49:28.809-04:00Great presentation Japheth!
