When the task is finished, we should get a photo of Bojun Guo so that we can make a marble or bronze bust of him to put in the chess hall of fame.
Right next to the bust of Ronald.
Taking ideas is not a vice, it is a virtue. We have another word for this. It is called learning.
But sharing ideas is an even greater virtue. We have another word for this. It is called teaching.

I want to see his photos and show him in my article about EGTs. Does anyone have or know where to look? :D

All 7-piece tables have been built. I have also renamed the folder(removed "_testing").

Now the full set is at:
ftp://ftp.chessdb.cn/pub/syzygy/7men/

Final sizes:

Code: Select all

151G    ./3-6men
12T     ./7men/4v3_pawnful
2.4T    ./7men/4v3_pawnless
2.3T    ./7men/5v2_pawnful
660G    ./7men/5v2_pawnless
117G    ./7men/6v1_pawnful
87G     ./7men/6v1_pawnless
17T     ./7men

Code: Select all

First file built:
2018/03/19
Last file built:
2018/08/20
Exactly 5 months!

Congrats! It's a milestone.

I still haven't bought more disks. Have to plan that at some point…

Wow, congrats!!!!

Quick glance, I see some amazing things, compared with Lomonosov EGTB:
- so short building period (5 months on non-supercomputers vs 6 months supercomputers)
- so small size (17T vs 150T)

----
Now I am curious about 8 men. Perhaps they will take about 4 years and 200T to build on non-supercomputers? Doable :?:

Amazing milestone. Now you might demand few quite days following. What is the next plausible project?
