For the benefit of folks unfamiliar with gfinds options these correspond to width 26 even, 27 odd and 27 odd with a central column of dead cells. That last search would also have found any width 13 asymmetric spaceships.

I think there is a good chance (I.E. maybe not very likely, but the best so far for a 2c/9 partial) that it can be completed.

dvgrn wrote:Yes, lifesrc has been a great tool, but it does still succumb to combinatorial explosions without really allowing for any good workarounds.
The only exception I can think of (there are probably others, but I'm not enough of a lifesrc expert to know) is the "Combine Solutions" option in WLS/JLS, which allows for a new filter to be set up partway through a search. Basically it amounts to "Okay, now show me something that isn't like anything I've seen so far."
In another topic, dvgrn wrote:The variant of this idea that I've been trying to get a handle on for years, is a hash-enabled WLS/JLS. The key would be successful partitioning of the problem: if there were a way to monitor the search and recognize that a lot of searches were being duplicated because Section A was actually completely independent of Section B, then it would be possible to run a Section A search just once, and a Section B search just once.

I also double checked the results for periods 1-4 and (2,0)c/5 with WLS.
I also added a 'Known spaceships by height' section, which gives the minimum-possible or maximum-searched height for ships of periods < 8. These were all checked by myself using WLS.

Did you do search of this type with WLS?
