Another possible reason could be for SIMD (vector) parallel processing. Years ago, I was a real-time image processing guy. Some time back, I did a back-of-the-envelope design for doing?light playouts on multiple go boards at once, on a dedicated parallel processing card. It meant?tiling all these boards into a large?image and using standard image processing-type operations. Avoiding single-stone suicide looked easy. Avoiding multi-stone suicide looked like a can of worms.
If some one wanted to use, for instance, a graphics card to do fine grained parallel processing, permitting multi-stone suicides might be a tempting option. - Dave Hillis -----Original Message----- From: Don Dailey <[EMAIL PROTECTED]> To: computer-go <[email protected]> Sent: Tue, 15 Jan 2008 1:43 pm Subject: Re: [computer-go] On average how many board updates/sec can top Go programs do these days? I think the only reasonable argument for suicide in the play-outs is speed. It's possible to improve the speed of play-outs significantly if you avoid the suicide test. But I'm convinced that it comes at a price. Suicide is the best move very rarely, and in rule-sets that do not allow it, it's NEVER the best move and it makes no sense to include them in the play-outs. - Don Christoph Birk wrote: > > On Jan 15, 2008, at 10:00 AM, [EMAIL PROTECTED] wrote: > >> Um, by easier I mean faster.
