This applet tests out all combinations of 4 strategies for the Extended Prisoner's Dilemma:
  1. UC: Unconditional Cooperation
  2. CC: Conditional Cooperation
  3. RC: Reciprocal Cooperation
  4. UD: Unconditional Defection

The separate Frequencies Frame plots the time series. See the EAME site for an explanation of the triangular Simplex dispay.
