Brent- Thank you for much for posting your Reversi code on the web. I have a very sharp 9th grader TAing my intro to programming class. (Because kids have to be in at least 10th grade to take the class, he is not allowed to be an official student.) The Reversi game has been a wonderful experience for him. For example, he has written code to consider move trees, and has a few different ways of evaluating the trees for his next move. Your code is very nice in that the student does not have to worry about the details of how you programmed the game. S/he can focus on strategies. Sam has also written a program that plays Reversi in batch mode so that he can has the computer play thousands of games to test his strategies. -Bruce Bruce Cohen | e-mail: bic@cgl.ucsf.edu Lowell High School | http://www.cgl.ucsf.edu/home/bic
