Symbolic, with some help from Oscar, has now finished over 5% of the needed results. Arkan has produced another 20+% of the results so far, and in future status reports I'll include more summary information about the merged effort.

New links for weekly status reports

Post by sje » Mon Jan 05, 2015 3:42 am

New links for weekly status reports; now organized by year.

2014, from:
https://dl.dropboxusercontent.com/u/316 ... 2014-08-10

to:
https://dl.dropboxusercontent.com/u/316 ... 2014-12-28

2015, from:
https://dl.dropboxusercontent.com/u/316 ... 2015-01-04

Note that while production mode started on a Friday (2014-08-08), each weekly report carries a Sunday date. There is no good reason for this. Also, there is no detailed data for reports 2014-08-10 to 2014-09-07 inclusive. There is no good reason for that, either.

From work unit wu7.055, a new maximal subtree perft(7) value:

And a non-zero minimal value

Post by sje » Fri Jan 16, 2015 9:44 am

For non-checkmated positions, the minimal subtree perft(7) count so far comes from work unit wu7.058:
[d]rn1Qkbnr/p2ppppp/b1p5/1p6/8/2P5/PP1PPPPP/RNB1KBNR b KQkq - 0 4[/d]
Subtree perft(7) = 73,936,990
