I think what may have happened is that the amount of information in the slice files dramatically increased as a result of the fairly high with with such a low velocity search. Try running (1,0)c/10 with margin=5, and seedcolumn=0. It finishes in about 12 minutes with my 6 core machine, so it should ...

A weird thing happened when searching for a 2c/6o. A c/3 (unsimplified) popped out.

Code: Select all

Ship

That's normal. Zfind doesn't check if the ship is at full period or not unless told to. You can use the f command to give a length after which the partial must be full period.

Does anyone know how I could go about trying to extend the small asymmetric bits of this C/8 partial with ikpx? x = 27, y = 43, rule = B3/S23 13bo$12bobo$9b2o5b2o$8b5ob5o$11bo3bo$6b2ob2o5b2ob2o$6b2o11b2o$5bo15bo$ 6b2o11b2o$5b3o11b3o$6b2o11b2o$4bo2bo11bo2bo$5b3o11b3o$5b2o13b2o$5bo15b o$3bobo15bobo$3b...

Yes, I compiled qfind-c8-ext.cpp. I'm not sure why it did this.

I ran extend0006-02, and it gave a ship0001 file, but the pattern in the file is definitely no ship: x = 19, y = 43, rule = B3/S23 5bo7bo$5bo2bobo2bo$4bo9bo2$bo6bobo6bo$bo5bo3bo5bo$4bo3bobo3bo$6b 7o$b6ob3ob6o2$o3b2o7b2o3bo$bo2b2o7b2o2bo$2b4o7b4o$2bo3bob3obo3bo $b2o2b2o5b2o2b2o$b2o3b2o3b2o3b2o$2bo2bo...

I would say afind is pretty dead, but I'm not sure it was ever alive. That was before I was around here at least.

The pattern definitely does not approximate a perfect circle. It has ever-growing flat edges on 8 sides, with round bits in-between. The longer it goes, the larger those straight bits get, never approaching a circle. The rule is a modification of the normal von Neumann neighborhood Abelian sandpile ...

I ran a search for the loafer (seedcolumn = 3) to see how long it took, and it took about 2 hours and 50 minutes to find it. I'm not sure what to compare to, but that seems really fast.

3c/8 odd width 12 was negative with LSSS. About how long did the search take? Are you running the width-25 3c/8 gutter search? In total for that search, all of the searches combined probably took over 16 hours, but that's estimation (it was probably a bit more than that), as I deleted the logs. I u...

Interesting. I take it you used search_P7H2V0EVEN24.sh provided by Andrew. Yes, I did. Do you understand how starts differ, and can give an example as to how they work? I really don't get what changing starts does, besides changing displacement with the number specified. EDIT: Changing starts defin...

How can we know when all possible starts have been reached when searching? Alternatively, how can I verify that I've ruled out speed at a certain width? I also am still confused about exactly what the diagrams mean in relation to the ship.
