Automated tuning... finally... (Topple v0.3.0)

[CMCanavessi]

In the end, I let the gauntlet finish. It was a huge improvement even though the rating and the % came down a bit after more games:

Topple v0.3.2 x64 157.0/240 (65.4%)
Topple v0.2.1 x64 118.0/240 (49.2%)
Topple v0.3.0 x64 115.5/240 (48.1%)


Current ratings:

Topple v0.3.2 x64 : 2552.5
Topple v0.2.1 x64 : 2424.9
Topple v0.3.0 x64 : 2421.7
Topple v0.2.0 x64 : 2413.3

So I've written some more search improvements which should score another 50 or so elo:

I'll try to make some more changes before releasing Topple v0.3.3 later. I think I'll also have to remove Teki from my gauntlet.

Wow, really nice!

Topple v0.3.3 has been released, which has several search improvements for an estimated gain of around 50 elo.

Binaries can be found here: https://github.com/konsolas/ToppleChess ... tag/v0.3.3

I'm currently working on some eval improvements but everything seems quite fragile so not much is coming out of it at the moment.
