[math-fun] Marc Paulhus and BYN?
Does anyone know where Marc Paulhus is now? His email address at Calgary bounces. Arturo Magidin just pointed out to me that in the new release of Winning Ways Vol 4 (on p.892), they claim that Marc found a non-terminating game of Beggar- Your-Neighbor. But they don't cite or present the hand. WW also says, though, that Marc says that one out of 150,000 hands will not terminate, and I find that hard to believe -- I wrote a computer program (some ten years ago) that plays random deals, and it's played hundreds of billions of hands without finding one that cycles. So I'm hoping to find out what the story really is... --Michael -- It is very dark and after 2000. If you continue you are likely to be eaten by a bleen.
I'm copying this to Marc, who can best answer it. There is a paper somewhere --- too lazy to put my hand on it, but I attach a 2003-09-22 version of it, in case it is of help. R. On Wed, 2 Feb 2005, Michael Kleber wrote:

Thanks, Richard -- glad Marc is traceable. The paper you include looks old: I think it's from before he ran something in the Monthly unanswered questions column in February '99. In fact, that's outside the 5-year window, so on JSTOR: http://links.jstor.org/sici?sici=0002-9890%28199902%29106%3A2%3C162%3ABMN%3E... In particular the "very long hand" included in that tex file is the one Marc had in the Monthly piece. We first learned about each other while that was in press, and he added a note mentioning the significantly longer hand that was my record at the time -- the only time my name has appeared in that fine publication, I think. Ah, fame :-) --Michael On Wed, 2 Feb 2005 08:58:28 -0700 (MST), Richard Guy <rkg@cpsc.ucalgary.ca> wrote:
