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...

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. OK, so you have to see if the new Agesa version fixes it. If you have purchas...

Re: Ryzen problems - AGAIN!

Previously I had 100 Zen1(Ryzen) chips and they all had the segfault bug, took me more than 3 months to "reproduce" the bug, then 2 attempts before an RMA: the first attempt failed when I told them I had 100 of them, they kick me back and forth between the distributor and AMD customer service, the ...

Re: Dylan Sharp Vs. Harvey Williamson (G4)

I'll let my moves speak for myself, then. Sounds like a plan... rnbqkbnr/pp3ppp/8/2pp2P1/3p4/5N2/PPP1PP1P/RNBQKB1R w KQkq c6 0 5 Stockfish-dev has -1.31 at depth 62. A draw seems possible still, assuming White simply continues to follow the line Stockfish has been showing for much of the game. Well...

Re: Dylan Sharp Vs. Harvey Williamson (G4)

2.c4 would have been the most fun, but I can't guarantee a draw in that one. 1. g4 d5 2. g5 e5 3. d4 exd4 4. Nf3 rnbqkbnr/ppp2ppp/8/3p2P1/3p4/5N2/PPP1PP1P/RNBQKB1R b KQkq - Nothing personnel, but I don't think you can guarantee a draw in this line. My analysis is getting high negative scores even o...

No NN, just MCTS. It will beat me.
As for an NN + MCTS on a GPU, I think even a 16x3 net will beat any human (if the engine is built well, allowing for hundreds of thousands of "nodes" per second).
Really?

That would be a novel approach. I would like to see that.

Re: There Might Exist Simple Rules For TT replacement

The GPU (more exactly the NN) evaluation contain the result of the many millions games played during self learning. Enhancing the number of played games and the measure of NN we can gain engines playing better and better games. It is pity but bigger NN needs more powerful hardware. For solving spec...

Re: Dylan Sharp Vs. Harvey Williamson (G4)

1. g4 d5 2. g5 e5 Lot's of possible moves here. I briefly looked at h6 and e6 but e5 looks the most natural. g5 was not a move I was expecting so will be interesting. The first occurance I have of 2.g5 was by Henry Grob played in 1964. That makes it an appropriate move to play in this game! I don't...

Re: There Might Exist Simple Rules For TT replacement

{snip} From a theoretical perspective I think this is wrong. e.g. if a mate in 50 is on the board and I insert into the TT the major sub-trees leading to it, the engine should have little problem finding it. {snip} The question is, how did the mate in 50 get into the hash table in the first place? ...
