Cwtch 5

Cwtch 5 is a complete rewrite of Cwtch 4, which was mostly a C translation of Lozza.

There is no multi-threaded search capability. The default hash is 256Mb.

The network is 768->(384*2)->1 SqrRelu trained on Lozza data. Cwtch 6 will have a new 'zero' network trained on Cwtch data.

Search is mostly Fruit era tech. and improving that will be the focus of Cwtch 7.

There are Linux and Windows (.exe) binaries below. Try the x86_64_v3 (AVX-2) version first and only fallback to x86_64 if you have problems, as it's a lot slower. _v4 can be ignored.

Cwtch 4

New net trained on more self play games.

Cwtch 3

Use a 768->(384x2)->net trained with bullet and self-play games.

Cwtch 2

A C translation of cwtch1.js still using the small 768x75x1 net.
