For machine learning experiments I'd like to locate thousands of sgfs of games between non-experts, to contrast with those of experts as found on GoGoD. Can anyone advise how I might get my hands on such? Arthur ___ Computer-go mailing list Computer-go

I cannot remember who/what I read that mentioned a "gridcircular" measure of distance - contrasting with Euclidean and Manhattan. It is something like max(Hseparation,Vseparation) + ( 1/2 * min(Hseparation,Vseparation) ) If anybody can help, with claiming it, or naming its inventor, or espe

I confess I did not think of the existence of correlations. I simply thought 1.2% was quite low, wondered how that could be, and marvelled at how close this simple calculation came to that result. My feathers may deserve some ruffling - but I remain obstinately mellow! Anyway, fwiw, it was my

Intriguing! A position is obviously illegal if any point is occupied by a stone surrounded by opposite-colour stones. At the 4 corners, 25 out of 27 combinations will be legal. The proportion (25/27)^4 will survive. At the 68 edges, 79 out of 81: (79/81)^68 will survive. At the 289 interior

To my mind, it becomes useful when the distances are much larger, when thresholded with an exclusive odd-number upper limit it generates dodecagons, which pleasingly approximate circles. Arthur On Jun 18, 2010, at 12:53 PM, Petr Baudis wrote: On Fri, Jun 18, 2010 at 08:45:14PM +0900, Darre

Thanks, that is where I saw it recently. However I don't see the name "gridcircular" used. Also, the diagram on p51 has strange numbering: centre point is 1, going out along axes we see 1,2,4,6,9,11,13 - only the 2,4,6 make sense to me. Arthur On Jun 18, 2010, at 11:48 AM, Petr Baudis wrote

[Computer-go] name for distance metric

2010-06-18 Thread Arthur Cater
Is there a formal name for this distance metric? distance=C.(dx+dy+max(dx,dy)) where C may be 1 or 1/2 , it doesn't much matter. And in which well-known Go program(s) is it used? I'm sure I've seen something about it recently but damned if I can find it again. Help much appreciated.
