Lectures by Aaron Siegel at the Weizmann Institute

December 19, 2006 at 6:12 pm (algebra, kayles, lectures, nim, papers)

Aaron Siegel has come back from Israel where he gave five two-hour lectures on misere games.

  1. Normal play
  2. Octal games and misere play
  3. The periodicity theorem
  4. More examples
  5. Further topics

Students and faculty from the Weizmann helped Aaron prepare excellent notes that are now available (PDF).

Many thanks to Aviezri Fraenkel at the Weizmann Institute for creating this opportunity to spread the word about misere games and their intriguing algebra!

Misere quotients for impartial games

December 4, 2006 at 11:45 pm (abstracts, algebra, math, papers, software)

Elwyn Berlekamp suggested that the title of my recent paper with Aaron Siegel, The Phi-values of various games, be changed:

I urge you to change the title. I think you have a good chance to make an impact well beyond the small circle of experts such as those who come to conferences like the one in Banff. There are many more mathematicians and algebraists out there, as well as a big computer Go community. Terms like “Phi-function” are unlikely to become buzzwords that stick, as there are many Phi functions defined by many different authors. “Misere Quotient” might well be a unique pair of words. It could quite plausibly become buzzword that would help stir up more interest in combinatorial games in general. So I think it important that your title include that pair of words.¬† I’d propose¬†a short title such as “Misere Quotients for Impartial Games”.

It’s hard to argue with that, and it’s still a preprint. So Misere Quotients for Impartial Games it is!
