Description
List of eleven prisoner's dilemma strategies (Fudenberg, Rand, and Dreber 2012).
Usage
data(strategies.FRD2012)
Format
Each strategy is encoded as a data.frame object. The rows of the data frame represent the states of the automaton. The first row is the start state of the automaton. Each data.frame object contains the following variables:
prob.d
Probability to defect.
prob.c
Probability to cooperate.
tremble
Probability of a tremble.
tr(cc)
State transition for the input cc.
tr(cd)
State transition for the input cd.
tr(dc)
State transition for the input dc.
tr(dd)
State transition for the input dd.

c("ALLC","TFT","TF2T","TF3T","T2FT","T2F2T","GRIM","GRIM2","GRIM3","ALLD","DTFT")
The prisoner's dilemma strategies are:
- ALLC
Strategy which always cooperates.
- TFT
Strategy which cooperates unless the partner defected in the last round.
- TF2T
Strategy which cooperates unless the partner defected in the last two rounds.
- TF3T
Strategy which cooperates unless the partner defected in the last three rounds.
- T2FT
Strategy which cooperates unless the partner defected in either of the last two rounds.
- T2F2T
Strategy which cooperates unless the partner defected for two consecutive rounds of the last three rounds.
- GRIM
Strategy which cooperates until one player defects, then GRIM defects forever.
- GRIM2
Strategy which cooperates until two consecutive rounds occur in which one player defected, then GRIM2 defects forever.
- GRIM3
Strategy which cooperates until three consecutive rounds occur in which one player defected, then GRIM3 defects forever.
- ALLD
Strategy which always defects.
- DTFT
Strategy which starts with defection, then plays according to TFT.
