Low/Hi Clue Thresholds

LCT-19 Progress

Postby Mathimagics » Wed Oct 09, 2019 8:25 am

At the end of week 8, we have:
Code: Select all
 known 17-19C:   144,490,098
 added    19C:   975,263,602  Week 1
                 917,301,757  Week 2
                 451,939,607  Week 3
                 507,056,483  Week 4
                 358,256,360  Week 5
                 543,137,278  Week 6
                 467,361,125  Week 7
                 211,939,044  Week 8
               =============
               4,576,745,354  Total resolved
                 895,985,184  Unresolved


A slow week - not because of reducing yields so much as a reduced batch production level (we've lost one of our 3 data mining sites!):
Code: Select all
Week 8:
       Date  Grids   New   Yield
  ------------------------------
  1   4 Oct    805    50   0.062
  2   5 Oct    800    46   0.057
  3   6 Oct    772    37   0.0482
  4   7 Oct    810    41   0.0504
  5   8 Oct    805    39   0.0478


Good news, perhaps, in the last 3 yield figures - all ~4.8%. Explicit grid testing based on current sampling costs 40ms/grid, and this corresponds (roughly) to worker yields of ~2%, so we will keep on going with the current mining operations! 8-)

It looks like the "relative yield" -- (% yield)/(% unresolved) -- has stabilized at ~30%.
That's good !

Yes ... because its as predicted 250-300k will be no 19C grids ....
and the new 19C finder will surely be an improvement too !

The no 19C grid solutions will be known soon.

Regarding the 18C - i wonder what proportion of 18C puzzles are "untouchable" ? [ no non-isomorphic puzzles within {-1+1} ] - these wont be found as easily as the rest !!!

I found an untouchable 21C some time ago - which might be rare - or maybe just flukey

here i posted - "new " challenges !!!
