I'm particularly interested in application of Life like cellular automata for a model of self replicating macromolecules, the beginnings of biological evolution. Is it possible then to create replicators within highlife that reproduce themselves and also random noise each generation or some generations?

Tezcatlipoca wrote:That is very interesting as well, but I am asking after whether it's possible to design a pattern of cells, a replicator under existing Highlife rules that spawns a replicator like itself plus noise in the pattern (or better yet a slight chance of noise in the pattern) of adjacent cells around it.

Tezcatlipoca wrote:If this is not possible, is there anyone here generally interested in creating cellular automata that more closely resemble biological evolution?

In a sense the suggestion you're making seems to be at not quite the right level: you're thinking about making changes to atoms one at a time (the ON and OFF cells of HighLife) where what you want to be able to change are some kind of highly stable information-carrying groups of atoms

Tezcatlipoca wrote:Do you mean it's not possible or not practical to devise rules that while handling things at the individual cell level of change (I'm assuming something about how this works I guess, is it not in sequence reading from left-to-right then in rows from top-to-bottom each turn?) still preserves things as a group?

Tezcatlipoca wrote:What's to say we wouldn't see something emergent if we ran a pattern like this fast enough and long enough. It's been getting slower and freezing on me relatively quickly. Do you happen to know any ways I can optimize the Golly environment or my machine to run this maximizing the speed, longevity, and size of bounded area (I'm sure bounding it helps with resources?) for this pattern.

Tezcatlipoca wrote:Do you mean even over the long term that unbounded does better? No matter how large even this extraordinarily complex pattern that doesn't calm down expands to, it takes less memory than a bounded grid?

Tezcatlipoca wrote:@c0b0p0 Thanks for the pattern. Very cool.
