Re: amling search program principles discussion / brain dump

Placeholder for the details of how the CA check works and in particular the table-makery and PEXT nonsense that speeds it up. I assume these are least interesting of anything I'm going to write, but I'll come back and fill them in if someone wants to know. I'd love to hear the pext bit twiddling. (...
