the 10'000 is simply because the timeout limit is 10 sec; ignore that.
you can see how the input/output is here
http://theaigames.com/competitions/warlight-ai-challenge-2/getting-startedso pick_starting_region 10000 3 9 10 13 16 means your bot have to pick starting regions and 3,9,10,13,16 is the possible territories to pick. I recommend you print the bots output, use System.err.print() to do that.
