I hate tau. An event like this should be viewed as a cool nerdy thing, a celebration of the culture and fun of mathematics. Thanks to tau, nerds start bickering over a senseless and useless distinction as to whether a factor of two should be present in a transcendental constant. Did we really need another pointless division and source of argument in our society?
About the bug:
Try to trace() out a few messages in your make_move() function, that might tell you whether something went wrong (the logs will appear at the bottom of the game replays.)
Yeah, we're seeing the first problems with that right now- newly uploaded bots progress faster than they should because they play against a more "diluted" pool of opponents than the oldtimers did.
We'll think of something.
I also think your alpha-beta bot is objectively better than the (currently) #1 bot.
Easiest thing to throw together now is a script which just feeds the whole game history into bayeselo as a bunch of fake chess matches, with the white move advantage set to 0. That's what was done for Tron.
I go redirected to this link www.scribd.com/jobs/botrace_upload_bot
which then displays: Oops! Something went wrong.
We're working on a fix. Please visit our homepage for some recommended reading to take your mind off of it.
