Re: [computer-go] [OT] All-integer scalable distribution algorithm.
while neither a normal distribution nor integer based, the following is relatively fast and may be useful for you (you might need to slide things around so that you get the maximum value where you want it and ignore the rest) check out the poisson distribution: http://en.wikipedia.org/wiki/Poisson_distribution there is helpfully an algorithm from knuth around the middle of the article that is quick. i take it that you want to go from a uniform distribution to something weighted more on one side than the other, for a finite number of possible values? if there's no strong reason that you want it to be half-normal, then there are a ton of distributions that can serve that need and might be easier to deal with in code. i suggested the poisson because it's something like the binomial, which itself is quite a bit like the normal, only very heavily based in a finite number of trials. (i'd prefer the binomial, but that might mean precomputing a lot of little tables ahead of time). s. __ Do You Yahoo!? Tired of spam? Yahoo!

What scoring mode are you using? /Gunnar SORRY - I was completely wrong here, I just realize that I was still using GnuGo 3.6 for scoring instead of 3.7.10! (for chinese : --score estimate --chinese-rules for japanese: --score estimate) In my actual computer Go tournament I just set up SmartGo2.7 to play GoIntellect10, and from 150 9x9games there are 7 with a seki in the final position. 5 of these were scored wrongly because I mistakingly had scored with GnuGo3.6 - I now have changed it to 3.7.11 and everything seams to be perfect! With GNU Go 3.6 you can try --score aftermath instead. It plays out the game until all stones except ones in seki are unconditionally settled, which usually gives a reliable seki detection. Also with current development versions --score aftermath is expected to be the most reliable scoring option, but the difference is much smaller nowadays. /Gunnar ___ computer-go mailing list computer-go@computer-go.org http://www.computer-go.org/mailman/listinfo/computer-go/
