public class JPtftCellularAutomata

extends JCellularAutomata

A graph paper grid populated with JCell objects which play localized cellular automata games. Each cell can have one of eight possible Markov strategies specifying how to respond to neighboring cells, plus the polymorphic PTFT strategy:

0 = 000 = AllD (always defect)
1 = 001
2 = 010 = STFT (suspicious tit-for-tat: D-then-TFT)
3 = 011 = D-then-AllC (defect only the first time)
4 = 100 = C-then-AllD (cooperate only the first time)
5 = 101
6 = 110 = TFT (tit-for-tat: C-then-TFT)
7 = 111 = AllC (always cooperate)
8 = PTFT (TFT with one's own kind, AllD with others)

A cell with a PTFT (prejudiced tit-for-tat) strategy plays TFT (tit-for-tat) against its own kind -- neighboring cells that have the same ethnicity -- but always defects against anyone of a different ethnicity.

Calling playRound evolves the cellular automata one gerenation by having each cell play 200 games against each of its eight neighboring cells. The points from each of the eight interactions are added up and become the cell's score. Each cell then adopts the strategy of its most successful neighbor -- the neighboring cell with the highest score. The updating is instantenous; the entire array is switched to the new strategies in one shot, not cell by cell.
