Connect Four referee for an AI battle.

Connect Four

This is an attempt to build an AI that plays Connect Four in Python.

Usage

Two files playerOne.py and playerTwo.py will be placed in the root directory. Executing the command python referee.py will import both players (AI strategies) and output the sequence of moves to STDOUT, and the winning player.

API

The playerOne and playerTwo modules should implement a Player class that has the following methods and attributes:

• an __init__ method that accepts the keyword arguments token and opponentToken, which will be characters. For example, a Player object will be initialized with: player = Player(token="1", opponentToken="2")

• a settable grid attribute that is a list of strings. Each row is represented by a 7 characters string where "0" is an empty cell, "1" has a token from you, "2" has a token from the opponent (or respectively with the tokens that have been initialized). See the following grid as an example:

["0000000",
 "0000000",
 "0012100",
 "0011201",
 "0121222",
 "0112121"]

• a move property that outputs an integer in range(7). In the previous example, it should probably output 2 if it does not want the opponent to win.

Rules

• 5 seconds thinking time per move. Any more will be disqualified.
• Any invalid move is disqualifying.
• Let the best AI win.

TODO

• Write the main loop for the Referee
• Write a dummy player with the right API
• Write a player module that takes human input
