Been there, done that, read the archives. For monte carlo random playouts I think the quickest known C++ implementation (libego) is about 6 times faster (600%!) than any java implementation. That is a relatively simple task, but a "real-world" one (as far as computer go is concerned), so until some advocate makes a really fast java monte carlo program I'm going to continue taking these "as fast as C++" claims with a pinch of salt. (I understand the very valid reasons for choosing other languages, and they've already been mentioned a few times in this thread; I was just replying to the "java is as fast as C++" rumours.) Darren P.S. A plug for an article I wrote for php|architect (phparch.com) magazine, Oct 2007 edition: I took a realistic data-processing PHP script that was running too slow (and using too much memory) and optimized it into C++, in stages, studying the return against programmer effort. The PHP version took 1m 18s, and 555M, for 1 million lines of data (and took 15-30 minutes to code). The easy-to-read-and-maintain C++ version took 20s and 146M (and about 30-60 minutes of coding). The optimized-and-rather-fragile C++ version took 16.5s and 128M (and another hour of coding). I ran out of (page) space and (programmer) time to then add memory pools. I would expect it to shave a few more seconds off, but not save any more memory. All the code (and script to generate test data) should be downloadable from the php|a site; if anyone tries it in another language (or optimizes the C++ version further) I'd be very interested to hear. _______________________________________________ computer-go mailing list computer-go@computer-go.org http://www.computer-go.org/mailman/listinfo/computer-go/
