CSCI 470/502E - Assignment 3 -100 pts                           

This assignment practices writing multiple Java classes, and using several Java library classes to do I/O and simple collection operation, such as Scanner, ArrayList and HashMap.

Note: Start early and work incrementally.

Game theory is a field of study that attempts to formalize games and investigate rational decision making. One of the classic examples of games studied is the “Prisoner's Dilemma.” In this assignment, you will be writing a program to play this simple game. In order to familiarize yourself with it, see http://en.wikipedia.org/wiki/Prisoners_dilemma

Flow of program:

The user will start their “session”. The “session” will be 1 or more games, each game is 5 rounds.

The user will first select an opposing “computer strategy”. Once the game begins, the user will play 5 rounds for one “game” against the computer with the strategy chosen. The user can cooperate or betray in each round. The computer can cooperate or betray in each round as well and then we reach an outcome for that round.

At the end of the 5 round game, a final score will be printed for the 5 rounds, and the player who had the lowest total years for that 5 round game will be declared the winner. Then the user will be prompted if they would like to play again in their session.  In addition, the program saves the statistics of all the games in the session based on date/time and when the session is over, an overall summary of all games played in the session will be printed before program finishes.

Scoring:

If both the players remain silent (both players choose 1), both get 2 years in prison.

If the player betrays (choose 2)  and the computer remains silent (choose 1), the player gets 1 year in prison and the computer gets 5 years in prison.

If the player stays silent and the computer betrays, the player gets 5 years in prison and the computer gets 1 year in prison.

If both the player and the computer betray (both choose 2) , both get 3 years in prison. Below is the summary, 1 means stay silent, 2 means betray.

Player, computer          player years, computer years

1,1                                   2 year   2 years

2,1                                  1 years  5 years

1,2                                  5 year    1 years

2 2                                  3  years  3 years

Example output (some strategy terms such as Tit-For-Tat will be explained later):
