Re: Weird results Tunguska 1.1 vs Jonny 4.0

I think after some games was discarded, Minic 0.47 4CPU on CCRL 40/4 is only missing 9 games to get an official rating again. Would it be possible for someone to run them again so that this version gets an official rating ?

Many thanks

Logged Sapeli's maximum moves from standard games against Fairy:
https://pastebin.com/HU2CQvZm

79 moves is the maximum currently.
I think 128 is plenty for gameplay. For analyzing 256 is bullet proof.
I agree. I really don't know how I've came up with the 512 initially ...

Re: Using evaluation hash score as current bestscore (initial guess)

Here is the idea :
- first write all margins under the form : a*depth+b
- second
* if static score is from eval : use the usual "a"
* if static score is from hash : only use a proper "b" (and a little "a"), make use of (depth-h.depth)

For group B, Minic shall be update to at least 0.62 which is an important bug fix release but i hope i will release an even newer version before it starts.

Thanks again for those tournaments.
