Concept of Prisoner's Dilemma in Problem Solving

 The prisoner Dilemma is an important game theory concept that is usually used in decision-making and problem-solving. 

Let us first understand the working concept of the prisoner dilemma by taking a traditional example. 

Suppose, two people have committed a crime but both are not confessing their crime and the police do not have evidence regarding their crime. 

Police take the help of the Prisoner Dilemma concept to solve this type of problem. 

In this scenario, 

Police take both persons to different Jail and ask them to confess. In this case, there are three scenarios:

First: If both do not confess their crime, there will be a maximum one-year punishment for both persons.

Second: If either of one confesses his crime and acts as a witness against the other opponent; there will be no punishment for the person who confessed. However, the other person will get 10 years of imprisonment.

Third: If both confess, there will be medium imprisonment ( like 6 years) for both persons.

In most cases, it has been seen that prisoners usually choose the second option as they do not have trust between them. This paradox ( mistrust between them) is known as the Prisoner Dilemma. 

Prisoner Dilemma occurs between India and Pakistan due to mistrust between them. Because of the Prisoner dilemma, both are in the race to hoard defense equipment and as a result, both face losses due to increased defense expenditure.
