Zurichess Nidwalden

[Norbert Raimund Leisner]

Hello,

https://bitbucket.org/zurichess/zuriche ... ew-default
mentions build version "Nidwalden", although it is not available here: https://bitbucket.org/zurichess/zurichess/downloads/ - indeed a little bit confusing. Can anyone of you make a Windows binary of Zurichess Nidwalden, please?

Alexandru´s statement:

Nidwalden is the development version and I don't normally release binaries for it. I'll see what I can do. Note that due to work reasons I was not able to continue development this year.

I’ll have a look when I’m back home from my cruise next Wednesday. I’m sure that when I compiled Zurichess Nidwalden for my Raspberry Pi with Go, it also compiled several other binaries for other platforms at the same time ....

Norbert I have PM’d you ....

Alexandru´s development version - result against chess engines with a rating beteen 2914 amd 2974 - no time forfeits, only one game vs. Toga was interrupted after a few moves

With the only notable change from the previous version being "go searchmoves" there will be zero difference in playing strength. I'm afraid you're wasting electricity on the Nidwalden version, Norbert.

That is not true. Overall the new binary searches 10% faster. Otherwise, the logic is similar.

The binary is built with the latest version of Go (1.11 vs 1.9), plus some inline funtions calls tweaking.

I remember that I posted some different binaries here: http://talkchess.com/forum3/viewtopic.p ... ss#p740729

I was hoping to get some input from the community. It's a different search, built from ground zero using evolutionary algorithms. I only guided the search a bit (by building the atom operations), but the whole logic is learned evolutionary. I think I didn't get on the parity of manual tuned search, was about 10-30 Elo weaker.

That is not true. Overall the new binary searches 10% faster. Otherwise, the logic is similar.

10% faster is good. Elo-wise it might translate into a +10 Elo improvement, which would need at least 4500 games to corroborate.
