Participants to the Turnament

1) Tit for Tat	this strategy will cooperate if the other did not defect
2) Tit for two Tat	this strategy will cooperate if the other did not defect twice
3) Tit for Tat - Trd	this strategy will cooperate if the other did not defect twice, but every 5 times it will defect
4) Tit for Tat - Rim	this strategy will cooperate if the other did not defect twice, every 5 times it will defect, but it will collaborate if it defected first
5) Always cooperate	this strategy will cooperate in any case
6) Always defect	this strategy will defect in any case
7) Random	this strategy plays in a ramdom way
