Hi,
I've got two lists of integers representing player strategies in a game.
I've defined a score function which counts the number of pair-ups where
the player came out ahead, like so:
strategy = {17, 3, 17, 3, 17, 3, 17, 3, 17, 3}; (* player's plan *)
score[enemy_]:= Count[strategy - enemy, x_/;x>0];
and I get a total score by comparing a player's strategy against a list of
possible enemy strategies:
totalScore = Map[score, strategies] //Sort //Tally
ListLinePlot[totalScore,{Filling->Axis}]
What I want to do next is create a new version of the scoring function,
with an interface like: score[p1_, p2_]. Then I want to Map each player's
strategy against the enemies, and see how they do.
Where I run into problem is how do I Map score[p1,p2] so that p2 is drawn
from a list of strategies? Something like Map[ score[p1,p2], strategyList].
Second question is: Is it possible to somehow thread both across the
strategyList?
