Re: Logic Life Search

Could you add an option to force the first row/column to be nonempty? That might be helpful for long and thin patterns.

rlifesrc uses lifesrc's algorithm. It is much slower than gfind for spaceships.

Anyway, if you want a non-totalistic version of lifesrc, or want a search tool which can run in your browser without compiling, you can try rlifesrc: https://alephalpha.github.io/rlifesrc/
