Re: Some speed tests with Leela and Allie

I don’t think he knows who he’s talking to.

Re: KingBase

Hi, What would you say about KingBase database ? What are your observations ? If I recall, this is a collection of publicly available PGN’s that has been around for a while online. It’s had TWIC games added to it, then it’s been de duplicated, cleaned and filtered by rating. It won’t have many engi...

Re: My failed attempt to change TCEC NN clone rules

one of the top Leela devs told me Ankan is the most important person in the project and although he spent little time contributing, his code is really critical as noone else knows to code for GPU, and without him cuda backend wouldn't probably happen . So for the record, you agree that the lc0 cuDN...

Re: My failed attempt to change TCEC NN clone rules

They all use essentially the same A0 network types, as that is dictated by the PUCT search algorithm. Really? Well, you probably want at least a move probability and some kind of winrate eval. That's not even an A0 innovation, although Alpha Zero was the first time I saw the networks for those outp...

Re: My failed attempt to change TCEC NN clone rules

I’m not sure if you realize this, but lczero and lc0 are two distinct engines. The first, lczero, was the initial chess engine used by the leela chess project and was derived from a combination of the leela go engine and stockfish chess board logic. The second, lc0, was a rewrite from scratch. I’m ...

Re: My failed attempt to change TCEC NN clone rules

Since Allie has been playing in the tournaments I have asked Ankan and he has said - most recently yesterday - that he is happy that Allie is using his cudann backend code and wished congratulations of success in TCEC. I’m sorry, the NVIDIA employee who contributed the CUDA code in the first place ...

Re: My failed attempt to change TCEC NN clone rules

You certainly have made very strong argument that Allie is a clone , regardless of what anyone points to as being different. And NN (scorpioNN, Stoofvlees) or MCTS (KomodoMCTS) are not clones. Not sure if it will change anything under the current infatuation state with anything neural. If you run S...

Re: My failed attempt to change TCEC NN clone rules

Crem,

If you look at the ScorpioNN graphs, they are also quite similar to the Leela kibitzer. I would suggest this has more to do with the nature of mcts.

Re: My failed attempt to change TCEC NN clone rules

As for code not being "particularly innovative": if you take a look into any chess engine, I'm pretty sure you won't find much "particularly innovative" there, and mostly either common knowledge or covered in chessprogrammingwiki. Still you cannot just take Stockfish eval and copy it into your engi...

Re: My failed attempt to change TCEC NN clone rules

If the speed bothers you, I’m working on a Julia version that should resolve that issue. Will it be even cleaner and faster than your engine in Golang that you've been writing since May 2018, and seemingly actively developed at least until April 2019 (and was "finishing" in February 2019)? :D Touch...
