tomitankChess 5.1

[tomitank]

Hi all!

Here is the new version of world stongest JavaScript chess engine!

- network is trained with 4M example instead of 2.7M as in the previous version. (same size 768x16x1)

- better hash table usage

- around 20 elo better than previous version

Estimated elo: 2900.

Since JavaScript is about 4-5x slower than C, it would be around 3100 or above in C. (With AVX).

JavaScript uses only one core. With 4 cores, in C it would be near to 3300.

I did not tune the search. It could probably be even stronger.

Its run in Browser or in Chess GUIs with node.js as well.

I welcome any feedback.

Have fun with tomitankChess!

After working on my own JS engine, I'm so much more impressed with what you've been able to get out of a JS chess engine.

>JavaScript uses only one core.

Have you looked at parallel search at all, especially since you already have web worker support?

Thanks!

Yes, i tested node worker. I tried to use for NN (parallel) calculation and wait only in Evaluation for result, but it's very slow.
