Come on, didn't you follow what happened?
Rebel-Tiger, commercial version, is by default EXACTLY the same engine than the
DOS engine that has been tested by the SSDF, with the only exception, that has
been checked by the SSDF and mentionned in their comments, that it computes
somewhat faster (about 8%). The difference only comes from the compiler used to
build the commercial engine, it is not a matter of optimized code.
But while the engine was tested by the SSDF, I was still working to improve it
(I had less than one month to do that). As I wanted to keep my promise that the
commercial version would play exactly like the version tested by the SSDF, the
improvements have been included in the commercial version but they are not
activated by default. I wasn't even sure when the master CD went to duplication
that these new settings were better or not!
The engine has been "frozen" by the end of November, so I had enough time since
that to check if the new settings are really better or not.
They DO improve the program's strength. So now there are 4 good reasons for the
SSDF to test the commercial product:
* it is somewhat faster
* it can use bigger hash tables
* it has improved algorithms
* there will be soon an opening book patch
I don't feel like I have betrayed anybody. I have kept my promise to the SSDF,
and my customers do get the latest and best engine I have produced.
What do you say about Fritz6 followed several weeks after by Fritz6a, and
Junior6 followed by Junior6a?
