groupD Snowdrift Strategy An Introduction
First, we play with devised “Tit-for-tat with forgiveness” for 20
times. Then, if our opponent is using tit-for-tat strategy and/or defecting more than cooperating, we response with a defect-oriented strategy. Else, we keep using the “Tit-for-tat with forgiveness”. Overview
tit-for-tat w/ forgiveness 20 ! tit-for-tat D>C opponent or "
# tit-for-tat w/ forgiveness yes no defect- oriented strategy
FLOWCHART
BEGIN
n = 1
output SM1 = C “SM” stands for a move made
by self.
get OMn “OM” stands for a move made by the
opponent.
n ++

n > 20 yes no OM(n-1)=D yes depth d =
20 “D” stands for defect.

on < 0.1
