Roughly how long did this search take to complete?

moebius wrote:In the search for a period 6 knightship I can report failure at widths 11, 12, 13, and 14. These searches failed to extend at approximately rows 24, 26, 28, and 30. The maximum extension pattern was approximately the same in each case. This is not encouraging.
I am two weeks into the search for a width 15 period 6 knightship, and it will either fail in about another two weeks or show signs of life and take months to complete. We will see what happens.

Hmm... Could you tell me why? I don't have that intuition.moebius wrote: but means to me that unless incredible luck occurs no period 6 knightships exist at widths less than 17 or 18.
Wow! That does seem new! Congrats! And this tells me i) Nobody searched this with gfind or ii) We have a new fast program!moebius wrote:Width 13 period 5 diagonal (1,1)/5 -- Ship found
I believe this ship is new and at a 63 pip minimum count it would be the second smallest c/5 diagonal ship.Code: Select allx = 25, y = 12, rule = B3/S23

Aha! Good to know Thanks!moebius wrote:I have run many searches over the years and I have noted that for almost any search as I increase the width the final partials get very long (5 to 10 times the width) at the widths just below where ships start being found.
No wonder you got something new and exciting. It sure is worth that 400 hours.moebius wrote:The c/5 diagonal search at width 13 ran 400 hours before it found that ship.

4 days and 4 hours, if that's what you're asking. And we're talking about non-stop here...
