Need help finishing implementing the Othello game in python.

Implement a heuristic evaluation function for the game of Othello. Use the files utils.py and othello.py. Extend the code in myothello.py to create a competent Othello player. Define a class that inherits from othello_player and modifies the methods calculate_utility and alphabeta_parameters. The first lets you set the default method that calculates the utilities of states as they are generated. The second lets you get more specific for each particular alphabeta_search call by setting the depth cutoff, the cutoff test function and the evaluation function. We will discuss strategies in class. the alphabeta_parameter method should work well for initial times ranging from 60 to 1200 at least. Change the name of the MyPlayer class to somehow indicate who your player is.

I'm struggling to find the utility of this game. What does the utility of this game means?
