Shutting down the distributed superpermutation search on Friday March 10

[Jay Pantone]

Hi everyone,

On this Friday, March 10, I'll be shutting down the web server that runs the "Distributed Chaffin Method" superpermutation search. Even though we were not able to fully solve the n=6 case, I'm deeply grateful to everyone who was able to contribute computer time and power to the search.

We knew from the beginning that there was no guarantee that the problem would be solvable and after well over 100 million CPU hours, we've been stuck on the waste=122 case for a year and a half. I am hopeful that there will be some theoretical advance in the future that proves the n=6 superpermutation is optimal, or that at least speeds up the search.

Thanks again to everyone who participated. It was a lot of fun! The results page here will remain active until Friday: http://www.supermutations.net/ChaffinMethodResults/

Best wishes,

Jay

Thanks to everyone who made this project happen! It's a shame this is how it ends, but I'm very happy that we tried.

Robin

Will this server be shut down too?
