Look at the two or three articles by Hofstadter in his "Metamagical
Themas" in Scientific American a year or two ago.  He reported experiments
on the repeated Prisoner's Dilemma game in an evolutionary context.
Without going into detail, the algorithm that survived best in a
free-for-all competition was one that always cooperated except when
confronted with an opponent who cheated the last time they met.

Incidentally, this relates to the "might makes right" question addressed
in a posting I just completed.  Under the circumstances of the game,
all participants had equal "might", but it was best never to use that
might first.  This corresponds to the Libertarian principle of "no first
use of force."  There might be some value in a discussion of this point.

By far the most important book on game and decision theory is *Games
and Decisions* by Luce and Raiffa.  Chapter 2 is indispensable since
it provides an axiomatization of the concept of von Neumann -
Morgenstern utilities, which is at the basis of game theory.  Game
theory is a misnomer for the theory of interdependent choice-making.
It deals with situations in which the choice or payoff of each
affects the choice or payoff of all, and vice versa.
