Re: Houston: We have lift off ...

Not abandoned, but put on lower priority. 30xxx is of course no longer "zero", so 20xxx is important if we care about being zero. sorry for being boring, and I ought really to know, but I don’t read much the AZ Discord chat. What aspects of 30xxx are no longer Zero? From discord: Tilps Yesterday at...

Re: what happened to scorpio NN in TCEC?

From what I gather it is not the fault of Scorpio but cutechess-cli. Apparently cutechess-cli only waits 10 seconds for an engine to load but loading Scorpio neural networks may take upto 30 seconds. It is not a problem for winboard if an engine takes an hour to initialize because the winboard prot...

Re: Houston: We have lift off ...

250 Elo points below 10xxx run with large 20x256 net. But these 20xxx and 30xxx runs with large nets run for months with only 100 Elo points better results than small net. 20xxx is IIRC already abandoned after several LR droppings Not abandoned, but put on lower priority. 30xxx is of course no long...

Re: Houston: We have lift off ...

I don't know why you are so enthusiastic. Runs 20xxx and 30xxx are pretty pathetic, especially considering how much resources they have eaten up. Some folks there have overdone something. Just a quick check with the latest engine (rc4) and one of the latest nets: TC: 60'' + 1'' Rank Name Elo +/- Ga...

Re: Is there a tool to ask the computer how it can understand code?

{snip} You should learn a bit about C++ before trying to understand C++ code. Don't those two things go hand in hand? But it probably would be a good idea to read Bjarne Stroustrup's books. Yes, I was going to say that too (the hand in hand). I find, since I restarted doing code recently, that ther...

Re: Komodo MCTS scales worse with TC than Komodo A/B?

I should have thought it was obvious, no testing required to know beforehand that Komodo MCTS sucks big time. As was stated much earlier, Komodo Team was simply trying to cash in on the interest generated at the time when AlphaZero wiped the floor with the alpha-beta Stockfish. MCTS without NN is a...

Re: B strategy is the future.

This human just knows what to do. Fast blitz can’t be played any other way.
For slower play it’s more or less the same, except one has time to think of the consequences, and during that process other ideas often emerge.
Is all entirely intuition.

Re: In anticipation of my RTX 2070 GPU :)

In at most a month I will have RTX 2070 GPU working on my desktop PC. I am just waiting to have a more diversified offer, maybe better cooling and maybe better prices. RTX 2070 gives a huge boost, a factor of 4 (!!!) compared to my GTX 1060 6GB. NVidia by allowing fp16 support, just blew out even m...

Re: Simple search idea, did anyone already try it?

DESPERATION_MODE_SEARCH: Suppose that your root position is down a large amount 'amt_down' from some previous iteration, and that the color for the root iteration is 'c'. Searching moves that continue to lose ground is more and more fruitless as amt_down gets bigger and bigger. My idea is that we g...
