New Stockfish version to be released next month

Post by Alex54 » Fri May 09, 2014 12:47 am

Today´s last Stockfish version is DD, but this situation will change very soon as the new one is going to be released during June.

The latest build is already around 52 elo points stronger than DD

New Stockfish versions are released every day on the development site.

Whether or not a particular version carries the label of an "official" release is irrelevant to me.

Can we be sure that the latest version from the development site is always the strongest so far?
If that was true, what is the point to release an "official version"?

The "official" version is a development version at a point in time.

Why do you think that only in June

I think that superfinal starts before June so a new official version is going to be released before June.

Yes, except just because they record a change doesn't mean that the stockfish team believes its an increase in elo. I started testing one of the "in between" versions as well, but I realized that I've had better results with DD than I did with the new development version, so I think when they finally release the new version, they would have believed it was an increase in strength.

As an example the stockfish team put in a command for "dynamic contempt" that is, contempt increases as stockfish has the advantage. I personally thought that was promising too. But then they took it right back and said after testing it didn't create a stronger engine. So you can see how its a work in progress and it is unwise to test every little development version. When they think the elo has increased substantially they will release a new version, and only then will I test it.

Tim.

dynamic contempt may give a little improvement or not but it is certainly not a regression in strength.

The cases of accepting and reverting changes is simply because of behaviour of marco when sometimes we accept changes without enough evidence only to revert them later

I think that it could be better to avoid it and do the relevant tests before accepting changes but it does not change things significantly.

The last developement version is practically always the strongest version or almost the strongest version and it is certainly significantly stronger than stockfish DD

I think that in more than 99% of the cases the latest version is
at most 5 elo weaker than the best previous version but even in that case it is clearly stronger than stockfish DD(the improvement from stockfish DD is more than 50 elo as you can also see in the FRC list).
