- I implemented the game Monopoly for my dissertation, where I coded the game and investigated the attributes an AI player should possess to win against different types of players. Once I determined which factors and attributes were instrumental in winning, I translated this into code to create the AI Player. The player was essentially built upon several parameters which formed the characteristics of the player I tested several AI players against each other to discover which set of parameters generated the highest percentage of wins. This data was then analysed and compared to determine which type of player and characteristics was best to win the game of Monopoly.
