[Computer-go] rent-a-supercomputer

Interesting article at http://www.theregister.co.uk/2010/11/18/amazon_cloud_sha_password_hack/ Their focus is the use of rented computer resources to crack passwords, etc. but the same principles could also apply to, for example, running large tests of computer go programs. See also

if you can get people interested in it, you can get it for free with BOINC (berkeley open infrastructure for network computing). this is how s...@home works, for instance, along with a bunch of other projects that come in and go out as they finish working over their datasets. you can get massive,

The latest version of Orego can be found here: https://webdisk.lclark.edu/drake/orego/orego-7.08.jar I've spent some time cleaning up the code; this version is particularly well-documented and devoid of dead-end experiments. Anyone who wants to start experimenting with computer Go in Java

Thanks Peter. I started using Orego for some of my experiments 2-3 years ago (version 3 I think) and I always found it very accessible, particularly as I'm not a strong programmer. I'd recommend it to anyone, whether you want to experiment with MCTS or other types of evaluation. On Mon, Jan 10,

I thought it already was one. What is the obstacle? (I don't have a spare machine to run it on, but anyone else is welcome to do so.) Peter Drake http://www.lclark.edu/~drake/ On Jan 10, 2011, at 1:07 PM, Brian Sheppard wrote: Is it now possible to make Orego into a standard opponent on

From that page (the weird numbering is a cut-and-paste artifact): Have a mix of algorithms to avoid mono-culture problems. I'd be happy to have Orego included in the mix. Use engines that aren't affected by the time limit to avoid variation between different PCs You can set a specific number of

Hi Nick, Thanks for the report. I have one correction: Erica was running on i7 950, 2 cores with 4 threads, **2.70 GHz, not 2.7 GHz. In the report you said pachi was running on 20-core system after round 4. Is that true? I remember Petr said pachi was running on single core for the whole

Hi professor Drake, I read your paper THE LAST-GOOD-REPLY POLICY FOR MONTE-CARLO GO and was very surprised with the performance of the heuristic The Last-Good-Reply Policy. In your experiment, it boosts the wining rate from around 40% to almost 60%. I wonder does this version of Orego feature
