Assuming that kgsGtp's way of compensating white for the handicap stones is incompatible with CGOS's proposed handling, (in other words, if it is the case that kgsGtp sends a komi value that does not include this compensation, even though the final score will. Is this true?) I would like to brief

2006-12-29 Thread terry mcintyre
Don proposed creating multiple entities for programs playing at different handicaps. That seems to complicate things. Is it possible to factor handicaps into elo-style ratings? We might start with some assumptions that, for example, 100 elo points is comparable to a one-stone handicap, test th

I agree with you. Weston's post convinced me that the program should know in advance what the handicap is to be and thus sending consecutive genmove commands is not really correct technically speaking. I don't like implied compensation, but apparently it is popular and KGS does it. However, C

I'm considering this proposal to rate handicaps separately, still haven't decided but it's appealing. My plan was to simply use the same scheduling algorithm I currently use. I would take the weaker "base" player and see if handicap versions of himself more closely matches the ELO rating needed t

using gen_move to place handicap stones seems unreasonable to me when there is a command intended for that purpose. The point of GTP is to make it easy to implement the protocol. Anything that either breaks programs that are written to the specification (as in using gen_move instead of free_plac

Okay. Don's later post does indicate that he intends to compensate for the stones. So, in the interest of being 100% clear: is this compensation included in the komi value that is sent to the client? Weston On 12/29/06, Weston Markham <[EMAIL PROTECTED]> wrote: Am I correct in inferring that

As someone who might write programs that will play on the server, I would like to put my 2 cents in: As long as the final score is simply the difference in the number of intersections controlled by each of the players, adjusted by komi, then I will be happy. Whatever compensation for the handica

This seems clean and reasonable to me. (Or you could just as easily have the server do the adjustment and set Komi to 3.5; that would also be consistent with TT rules). If my bot sees 2 black moves in a row, it can figure out it's in a handicap game. A bigger question to me is, how l
