Description
Distribution
gollark: > [Edit] Worth to note is that Gradual was designed to be a strategy that outperforms Tit for Tat. It has similar properties in that it is willing to cooperate and retaliates against a defecting opponent. Unlike Tit for Tat, which only has a memory of the last round played, Gradual will remember the complete interaction and defect the number of times the opponent has defected so far. It will offer mutual cooperation afterwards again, though.
gollark: The *description* of "Gradual" is pretty understandable.
gollark: How exciting.
gollark: Its score is actually identical.
gollark: ```scheme(define actually-forgiving-grudge (lambda (x y) (let* ( (defection-count (length (filter (lambda (m) (= m 1)) x))) (lookback (+ 1 (inexact->exact (floor (expt 1.8 defection-count))))) (result (if (member '(1 0) (take lookback (zip x y))) 1 0)) ) result)))```I think this detects betrayals properly now.
