Tournament results are in. Here's how we ran it:
Not surprisingly, any AI that didn't compile was not entered into the tournament.
For all pairs of AIs i and j, i played two games against j: once with i as the black player and once with i as the white player.
Any AI that threw an exception, had an infinite loop or infinite recursion, returned an invalid move, did not have a chooseMove( ) method with the proper signature, did not implement the OthelloAI interface, or took too long to make a move (5 CPU seconds) was disqualified as soon as the error was uncovered, and was not allowed to play any more games. (I should have also disqualified any AI that printed any output to System.out, but I opted to look past this problem. Still, the assignment makes clear that you should not turn in code that dumps output to the console--and as programmers, you should especially know that you do not send debug output to the console in the released (turned-in) version of code!
Any games played by a subsequently disqualified AI were thrown out. As a result, the number of games counted for each AI was the same. After all the games were played, the results of all games between pairs of AIs that were not disqualified were tabulated.
The order of finish in the tournament was determined by two factors:
The winning fraction, which was calculated using the formula: (wins + (ties / 2.0)) / games_played.
The total number of tiles earned in all games played, which was used as a tiebreaker if there was a tie on winning fraction.
Do remember that where you place in the tournament ranking, in and of itself, is not considered when grading your work.
The results
Player is the last four digits of your UCI ID# (or Access ID#). Total Record indicates your AI's total number of wins, losses and ties in games played. Win Frac is calculated as described above. Total Tiles is the total number of tiles your AI earned in all of the games it played. Record as Black and Record as White show the number of wins, losses and ties in games played as the black and white player, respectively. A java.lang.reflect.InvocationTargetException disqualification means that your program threw a fatal exception of some kind that triggered a secondary exception in the tournament program itself (one from which the tournament was able to recover).
