My test at fast control shows 30-40 elo gain in self testing, but it could be different at long time controls as usual.

Atlas 3.90

Hello all,

new version Atlas 3.90 available at https://sites.google.com/site/atlaschess/home/down.

After a short break, here comes a new version of Atlas. A small summary of the changes:
- First version in C ++ 11.
- Added popcount versions.
- General re-testing of eval parameters.
- Extensions: added singular extension.
- Disabled IID.
- Slight improvement in time management.
- UCI protocol in its own thread.
- FIX BUGS: corrected errors in:
1) the scaling of specific endings.
2) other minors in evaluation.
3) node count.
4) re-searchs in PV nodes.

My test at fast control (10s+0.2s) shows about 40 elo gain in self testing, but it could be different at long time controls as usual.

Regards,

Andres Manzanares.
