EXchess v7.96

Post by dchoman » Tue Jan 31, 2017 12:46 pm

Hi Everyone,

I've released a new version of EXchess at

https://sites.google.com/site/experimentalchessprogram/

v7.96 is considerably stronger than v7.92 in head-to-head testing at bullet time controls, but I haven't tested its strength against other engines. Most of the improvement comes from finding and correcting two bugs in the evaluation and one in the search; however, there are other minor improvements as well.

I had a couple of reports that v7.92 did not work on some older AMD processors, and it was suggested this might be due to compiler options. Unfortunately I do not have any AMD systems for testing, so I could not reproduce this. v7.96 is now compiled with a more recent gcc compiler version 6.2 using mingw without processor specific compiler options (only -O3 -pthread -static). The 64-bit version is compiled with the x86_64 mingw compiler and the 32-bit version with the i686 mingw compiler. I don't know if this will solve the problem on those older processors or not.

As always the source code is included so an alternative is to compile on your own system directly.

- Dan

It works on an Amd Fx-8350, not very old though.

I guess you started it with WB2UCI, because it is Winboard only?

ExChess has been one of my favorites since the dark ages.
Taking ideas is not a vice, it is a virtue. We have another word for this. It is called learning.
But sharing ideas is an even greater virtue. We have another word for this. It is called teaching.

Thanks for the report. Does it work in console mode without running it though CB? If so, then the issue may be something with the communication with the adapter.
