Rotor 0.7 released

[Jan Brouwer]

After a break from computer chess, I've caught the bug again, and have updated my program.
The new version can be found at https://sites.google.com/site/chessrotor/

Changes since the previous version are:
- continued refactoring of code
- added support for OS X
- castling bug corrected
- tuned pawn evaluation weights using CLOP

I tried tuning other evaluation weights using CLOP, but failed so far.
This may have something to do with badly reproducable testing results that I'm looking into.

Have fun,

Jan

Thanks Jan, I hope Rotor have soon a Ponder mode?

Good news. Thanks Jan.

I will add it to my todo list, it should not be too difficult to implement.

Yes, I am!

Before Rotor even promoted to 2nd division, now it is struggling to stay in 4th division.
Many of the mid-level engines have made good progress in the last year.

Thanks,

I have Rotor 0.4

How much stronger is the new version?

Thanks,

The difference between version 0.4 and 0.6 is about 110 ELO points according to CCRL.

I expect 0.7 adds a few tens of points, so perhaps (fingers crossed) about 150 ELO points in total.
