Prisoners Dilemma, Zero Determinant, Evolution

From: andrew cooke <andrew@...>

Date: Fri, 17 Aug 2012 08:51:30 -0400

Whoa.  This is big news and I completely missed it.

From
http://www.technologyreview.com/view/428920/the-emerging-revolution-in-game-theory/

  "In May, Freeman Dyson at Princeton University and William Press at the
  University of Texas announced that they had discovered a previously unknown
  strategy for the game of prisoner's dilemma which guarantees one player a
  better outcome than the other."

  [...]

  "Press and Dyson's discovery has sent game theorists scurrying to work out
  the implications. They've been using prisoner's dilemma to gain insight into
  everything from Cold War politics and climate change negotiations to
  psychology and, of course, the evolutionary origin of co-operation itself. 

  Today, we see one of the first paper's to study these implications in
  detail. Christoph Adami and Arend Hintze from Michigan State University in
  East Lansing investigate whether the zero determinant strategies are
  evolutionary stable."
