# Chad Game Theory Tournament
|
||||
|
||||
All is based on the Prisoner's dilemma.
|
||||
The tournament consists of consecutive games which consists of matches.
|
||||
In each match there are 2 players.
|
||||
Players must make a binary choice between `COOPERATE` and `CONFLICT`.
|
||||
|
||||
Below is a table of all possible out comes:
|
||||
|
||||
| Players | Action | Reward |
|
||||
| :------: | :-------: | :----: |
|
||||
| Player 1 | COOPERATE | 3 |
|
||||
| Player 2 | COOPERATE | 3 |
|
||||
| :------: | :-------: | :----: |
|
||||
| Player 1 | COOPERATE | 0 |
|
||||
| Player 2 | CONFLICT | 5 |
|
||||
| :------: | :-------: | :----: |
|
||||
| Player 1 | CONFLICT | 5 |
|
||||
| Player 2 | COOPERATE | 0 |
|
||||
| :------: | :-------: | :----: |
|
||||
| Player 1 | CONFLICT | 1 |
|
||||
| Player 2 | CONFLICT | 1 |
|
||||
|
||||
The player with the most points by the end of the Tournament wins.
|
||||
|
||||
To play, submit a header file with your subclass implementation of `Player`.
|
||||
Comments will further aid you.
