Hi Sidiki,

You can ignore the warnings. They are about the old evaluation function, but dragon does not use them any more. I will remove the messages in a new version later.

Hi Michel,
I've been waiting for 3 days and nothing is happening. Can you fix this or do something about it. Applies to program version 5.0. Screenshot from version 4.8.0 but the same thing happens.

Version 5.0.1 is now available

It fixes the "missing weights, poor performance" message. In retrospect it may have affected strength in some cases after all.

5.0.1 is much stronger than 5.0. In my internal benchmark the score moved from 42.5% win to 47.2% wins against scan 3.1. A yet to be released version does about 49.7% and i can see a clear path for further improvement.

5.0.1 introduces a new neural net for endgames with 8 pieces or less, which is used for the endgames that are not installed. Also the neural net is now split into positions with and without kings. Training is based on 607 milion positions that have been fully rolled out.

@Krzysztof if the database generator problem still persist, can you post a new image, and indicate which of the 3 buttons you used to start it?
