Re: Frisian draughts endgame

Marten Walinga kindly asked me to rewrite the above posts into a column for the tournament book for the 2020 Fryslân Open tournament (which includes a World Championship event in the 5v5 piece Frysk! variant). I was happy to oblige of course! See p13-14 of https://docs.google.com/viewer?url=http%3A%...

Re: Damage 15.3

You do understand that Google/Deepmind used 1700 years worth of computing *in parallel* in order to achieve all that in 4 hours? You trust too much Google. The 1700 years of computing comes from Gian-Carlo Pascutto, author of Leela-Zero, the open source program that actually reproduced the Alphazer...

Re: Damage 15.3

OK, i thought that it's was the same things with the weights. 👍😎 Thank It's both very similar and very different. Both A0 neural networks and Scan inspired patterns have their weights fitted using gradient descent optimization. But the A0 neural networks are much more complicated non-linear functio...

Re: Damage 15.3

The 4 hours of training for AlphaZero corresponds to about 1700 years of computing on a consumer-grade pc (estimate by the author of Leela-Zero, who managed to get this much resources by crowd-sourcing the computation). Such information should be treated humorously and joyfully, and do not believe ...

Re: Damage 15.3

Yes, with resources we can make the impossible. So these 1700 years of computing it's as a kind of database or Just to know what variant it's better.? I think > 90% of the computing time was used to generate self-play games, and the rest of the resources were used to find the optimal weights for th...

Re: Lidraughts

Technisch is het rechttoe-rechtaan, en alle broncode staat op GitHub. Maar klagen over missende features is natuurlijk leuker dan ze zelf implementeren. Rein, ik heb niet de indruk dat mensen hier nou zo hard aan het klagen zijn. Als de auteurs van lidraughts hadden aangegeven dat ze deze feature b...

Re: Lidraughts

Ben het met Wieger eens. Super storend dat je op deze manier zetten moet invoeren. Er is op het lidraughts forum wel vaker gevraagd om deze feature, maar is tot nu toe altijd afgehouden. Lidraughts ondersteunt namelijk een optie, waarbij je al een volgende zet kunt spelen als de tegenstander een be...

Re: Lidraughts

Lidraughts is open source, dus doe een pull-request met zet-completering ;) https://github.com/RoepStoep/lidraughts Het ontwikkelen van zet-completering is niet het issue. Het gaat er om dat men er heilig van overtuigd is dat dit een ongewenste optie is. Wat mij betreft is het aanklikken van alle v...

Re: Lidraughts

Voor mij is er een hele duidelijke reden om niet op lidraughts te spelen. Om zetten of slagen uit te voeren ben je verplicht om alle velden aan te klikken, en dat vind ik zodanig storend dat ik de site tot nu toe niet gebruik. Ondanks dat het er verder allemaal heel goed uitziet. Lidraughts is open...

No, 6/12 cores/threads, just as its predecessors (v1-v3)
