I'm sure they will be very useful for all the future bot writers too, to know what to expect. Just last question, what is "1.1 or 1.2 K"?

[computer-go] Congratulations to MoGoTW!
Congratulations to MoGoTW, winner of yesterday's KGS bot tournament. My report is at http://www.weddslist.com/kgs/past/51/index.html. It is longer than usual - perhaps because I found this event, with a very strong entry and a fast format, particularly interesting. As usual, I am sure there are errors, and I look forward to receiving your corrections.

Re: [computer-go] Congratulations to MoGoTW!
I think I can partially resolve a mystery: --- The Orego-housebot game got stuck in the position shown to the left. I don't know what state it had got into, but neither player moved, and neither timed out. Housebot had crashed, so I am surprised that this did not cause it to time out. SGF Anyway, I needed to assign a result to the game. There is an unresolved ko at the top edge. But even assuming it loses the ko, White (Orego) has 38 points on the board, and wins with komi. So I assigned the win to Orego. The way the KGS server works, if I assign a result, it is shown as a "forfeit" by the loser. The "forfeit" label on KGS usually indicates that the forfeiting player is a habitual escaper. But in bot games it merely indicates that some human intervention has occurred, and is not a criticism. --- housebot tried to declare all of the white stones at the top dead, and Orego disagreed. A cleanup phase was entered, and I believe housebot crashed during the cleanup phase. I don't know why that left the game alive with no clock ticking...

A cleanup phase was entered, and I believe housebot crashed during the cleanup phase. By the rules of the game end protocol, support for final_status_list dead is optional. kgsGtp incorrectly translates that to asserting all stones are alive, although I guess the net effect is the same. HouseBot crashed when the game was resumed because of some kind of quirk in how time data is tracked. I still have to investigate that. My solution, to avoid having Nick force results throughout the tournament was to restart my bot after it crashed. With luck, I won't crash in the next tournament :) I don't know why that left the game alive with no clock ticking... I'm surprised by this as well.

Ah, you mean the First Play Urgency! Thanks, I will try that. Anyway, I'm happier; after fixing many bugs and improving my playouts just slightly more, with RAVE, I'm getting around 50% performance against GNUGo even with only 5k playouts. -- Petr "Pasky" Baudis A lot of people have my books on their bookshelves.

Thank you for the tournament, Nick. It's quite interesting and exciting with many strong programs. Correction: In the picture of round 14 (bottom left of the page), it's not White turn but Black.
