Do you have any suggestions for the project? In particular I wonder if this problematic example should be stored and if yes, how.GUYTU6J wrote: ↑December 11th, 2019, 3:34 amHow about a new database that storages the way B-heptomino displace in some Life-like isotropic non-totalistic cellular automata? This can provide insights into the behaviours of INT rules.
In my imagination the information is stored in this format:where gen=generations for B to reappear, dx and dy=offsets in two directions, orient=new orientation of B, isorulemin and isorulemax=range of rules for the sequence. Orientations follow the conventions for Herschel conduits:Code: Select all
gen,dx,dy,orient,isorulemin,isorulemax
For example, B in Conway's Life evolves into some junk and a new B at gen=64:Code: Select all
x = 73, y = 37, rule = LifeHistory

Some issues I think of:Code: Select all
64,19,1,R,B3/S23-c,B34ce8/S234c5e8
I admit that I haven't gone through the general considerations, but the crude idea is potentially powerful.
- The database includes no information about what actually the B is. Whether B is a oscillator, a spaceship, a replicator or merely a methuselah is not relevant to the offset. (But the new orientation does suggest behaviours.)
- Why B-heptominos? For me, it seems more likely to be observed in soups for INT rules than R-pentominos, Herschels, buns or block&gliders. But this statement may be biased and I can't decide on other small methuselahs like bookends, pre-loaves and Pi's. There's even the isomeric B-heptaplet. Moreover, unnamed methuselahs in other rules exist. (A survey on the most common small methuselah across INT rules?)
- The junks around the new B may interact with B so quickly that the characteristics of B is interrupted.
- Multiple B's can occur simultaneously.
- The B-heptomino may never appear again in the evolutionary sequence, but one of its descendants reappears and shows its features.
- The database can be exhaustive, but it may turn out to be randomly collecting stuffs like the 5S database.
Code: Select all
x = 3, y = 4, rule = B34-a5ae/S23
