A game engine with 2 agents which can play Tic Tac Toe against each other. The agents could be Naïve or Thoughtful and will take decisions on their moves depending on the rules of the game. The main aim of the project is to think about strategies that an autonomous agent might use in playing a simple game (Tic Tac Toe), and to build a substrate for subsequent projects in which the use of Knowledge-Based AI techniques for Representation, Reasoning and Learning to improve and expand upon the capabilities of the basic game-playing agents that have been built here are explored.
