Re: Move repetitions in tree search + transpositions

I don't know if it is worth the trouble to reconstruct the entire shortest line(which may not be actually short), if the longer history that gets fed into NN (which is truncated) has virtually no influence in detecting repetitions. To avoid exploring them unnecessarily just expand them when they are...

Noob is only saying this cause is experimenting with extreme BIOS settings and expect them to work…
Exactly the opposite, I have no interest in trying anything other than defaults, and that is precisely my complaint is about.

Re: Database snapshot

s this database snapshot the same as the one accessible from https://www.chessdb.cn/queryc_en/ ? Something I noticed was that it had reached and surpassed 9000000K positions, but every time it'd go up eventually it'd go back to sub 9000000K. But recently it has gone down to 5000000K as if almost ha...

Re: Database snapshot

Well, here is the thing: There is no magic here, I cut corners by essentially refuting the lines with shorter depth searches, it still takes a substantial amount of computations to back this up by resolving those shorter lines including multi PV to their exact scores. On the other hand, I gave you t...

Re: Move repetitions in tree search + transpositions

By the way, in your example, I think there also exists many equivalently short lines to get to that position without involving double blunders, so it may not be the case that the only chance of expanding the node is by one particular bad sequence of moves that never worth exploring.

Re: Move repetitions in tree search + transpositions

we discard 1.Rc7 and never look at it again It still shouldn't stop you from expanding it under all circumstances. As the tree grows you will eventually expand one of these. Now this is a tricky problem of whether you want to force expanding the node when it is your main line, if you do that, then ...

Re: Ryzen problems - AGAIN!

Well the problem is already well-known: https://bugzilla.kernel.org/show_bug.cgi?id=196683 Basically what it takes to be safe is to either use a crippled kernel or a crippled BIOS, which disables C-STATES and turbo boost. What really frustrates me is that for stuff like CPUs I would assume them to ...

Re: Move repetitions in tree search + transpositions

Or do you mean we still expand it when the main line wants, but pretend the move history was from the shorter line so to speak? It is not a depth-first search, you do not need to always expand main line nodes to make progress, the search progresses by increasing overall expansion rate and that impr...

Re: Ryzen problems - AGAIN!

OK, so you have to see if the new Agesa version fixes it. If you have purchased a large quantity of MB's I would talk directly to your MB manufacturer as they may have a partial list of fix the new version will address and be able to give you a firm date when they will release new bios with the bug...
