Re: Weights file

[Joseph Heled]

Thanks, seems to be the same nets I am using - so no change in 1.01

The source file used by gnubg is in th CVS repository:
https://cvs.savannah.gnu.org/viewvc/*checkout*/gnubg/gnubg/gnubg.weights?revision=1.4

I have uploded it in the format used by gnubg-nn at:
https://alpha.gnu.org/gnu/gnubg/nn-training/1.01/nets/

There are no training_data or benchmark subdirectories of 1.01, I used
those of 1.00.


Do you know why gnubg uses a binary weights file ? I suppose parsing
100000 floating point numbers in text format used to be slow, but
nowadays it is barely noticeable, if at all, when starting the tty
interface and dwarved by the time the GUI takes to open.

Maybe we should get rid of this? gnubg already can read the text file ;
if there is no gnubg.wd file where it expects to find the weights file
it will try to read a gnubg.weights if there is one in the same place.
