I think that the bots already submitted should be considered for grandfathering if the rules change to prohibit them.

I also have a specific entry in mind, but lack the expertise to go from 'flowchart' to 'code'.

I would agree that they should compete even if they're not awarded prizes for winning. Because we should at least have a comparison with performance against old bots. More data is pretty much always better.

Prisoner's dilemma tournament results

The prisoner's dilemma tournament is over. There were a total of 21 entries. The winner is Margaret Sy, with a total of 39 points. 2nd and 3rd place go to rpglover64 and THE BLACK KNIGHT, with scores of 38 and 36 points respectively. There were some fairly intricate strategies in the tournament, but all three of these top scorers submitted programs that completely ignored the source code of the other player and acted randomly, with the winner having a bias towards defecting.

You can download a chart describing the outcomes here, and the source codes for the entries can be downloaded here.

I represented each submission with a single letter while running the tournament. Here is a directory of the entries, along with their scores: (some people gave me a term to refer to the player by, while others gave me a term to refer to the program. I went with whatever they gave me, and if they gave me both, I put the player first and then the program)
