The Research Of The Computer Technology Applications In The "Prisoner's Dilemma" Game Theory

In recent years, Game Theory is applied more and more widely in the economy decisions, particularly the typical "Prisoner's Dilemma" model plays significant role. Computer game simulation is the most effective method in various research methods.The "Prisoner's Dilemma" problem can be abstracted from the conduct of economic competition-cooperation and its basic model can be built up then. This model reflects the conflict between the individual rationality and the collective rationality. Many socio-economic activities have this kind of characteristics, the Price War is one example of the "Prisoners Dilemma" problem and the"Iterated Prisoner's Dilemma"model is raised for resolving the Price War problem .This paper explains the characteristics of "Game Theory": one's choice is affected by other's choices, and that turn over to affect other's choices. The conclusion of "rational person faces predicament" is derivesed through Nash Equilibrium analysing. Then two correlative computer games organized by Robert Axelrod are introduced. By analysing the results of these computer game contests, the reasons why the strategy"TIT for TAT"wins the games are pointed out.This paper introduces the seven strategies of "Prisoner's Dilemma" model in《The Evolution of Cooperation》("TIT for TAT ","downing ","always betray"," enduringly revenge ","Jose"," tester","revised downing") , analyses the corresponding algorithms and implements them by computer game simulation. Two types of game environment are achieved: two players'game and multiplayers'game.The successful development of the computer game simulation proves that the computer modelling and simulation are powerful auxiliary tools for economic theory analysis.
