make a pattern that doesnt trigger b1c and isnt a void

i dont think its possible

Assuming the usual topology "infinite square tiling", every two-state pattern with nonzero finite population has a (nonempty) bounding box. Take the topmost row of the bounding box of the pattern. Find the leftmost bit in that row. The cell to the left and above of that bit is a dead cell with exactly one alive neighbour which is a diagonal neighbour. That means the pattern necessarily queries the B1c condition.

One way around the impossibility is to change the topology. Here is a finite-population still life in B1c/S23, with the caveat that the topology is an infinite cylinder 7 cells high:

Code: Select all

x = 8, y = 7, rule = B1c/S23:T0,7

probably the hardest challenge i've ever concieved

construct a blockic
a) glider eater
b) reflector
c) structure, that when hit by gliders coming from at least 4 different spots, becomes 4 different (non-glider) spaceships without leaving behind junk (think dogun sagaqr, but instead of time adjustments, it's different spots)

c) structure, that when hit by gliders coming from at least 4 different spots, becomes 4 different (non-glider) spaceships without leaving behind junk (think dogun sagaqr, but instead of time adjustments, it's different spots)

Unless someone discovers more Blockic conduits soon, this challenge looks like it should be easier than the other two. Let the four spaceships be LWSS, MWSS, HWSS and the loafer, engineer one-glider seeds for each, and add additional one-time splitters and one-time turners so that when one of four one-glider seeds is triggered the other three are cleanly destroyed.

find an eater for this:

Code: Select all

x = 103, y = 103, rule = B3/S23

Ruletable based design idea implementation challenge

Choose some Life-like cellular automaton (e.g. CGoL, Seeds, Day & Night, ...)
Then create a multistate RuleLoader ruletable that would allow putting multiple different patterns in toroidal universes in a single stamp collection (as opposed to putting each toroidal pattern in a separate RLE).

For a concrete example, is there a sensible design via RuleLoader that would make it possible to put all patterns below in a single RLE, and display and evolve them all at once, "side-by-side"?

Code: Select all

#C p20, Seeds, 11-by-11 torus
x = 7, y = 7, rule = B2/S:T11,11
2bo$bo$o2$6bo$5bo$4bo!

Code: Select all

#C p78, Seeds, 14-by-14 torus
x = 9, y = 10, rule = B2/S:T14,14
2o$3b6o$2o5$7b2o$6o$7b2o!

Code: Select all

#C p418, Seeds, 14-by-14 torus
x = 9, y = 9, rule = B2/S:T14,14
3o3b3o6$bo5bo2$bo5bo!

[confocaloid]

These seemly meaningless line segments are actually a single natural p35 oscillator:

Code: Select all

x = 12, y = 5, rule = B3ai4wyz/S1e2aik3eiy4i5e7e
2o2$7bo$7bo3bo$7bo3bo!

[...]

In a different CA, the same pattern is a phase of a nontrivial p70 oscillator:

Code: Select all

x = 12, y = 5, rule = B3ai4ajnqrwz/S1e2aik3eiqy4iqz5jq7e
2o2$7bo$7bo3bo$7bo3bo!

In a different CA, the same pattern is a phase of a nontrivial p31 oscillator:

Code: Select all

x = 12, y = 5, rule = B2i3aiy4ajwz5any6/S1e2aik3eiy4ikty5eqr6i78
2o2$7bo$7bo3bo$7bo3bo!

In a different CA, the same pattern is a phase of a nontrivial p19 oscillator (however, note that this example is not a single strict object anymore; one of two dominoes never interacts):

Code: Select all

x = 12, y = 5, rule = B3ai4aw5a6i/S1e2aik3-acjq4it7e
2o2$7bo$7bo3bo$7bo3bo!

Evidently it is possible for a single pattern to be a phase of several different nontrivial oscillators, depending on the ruleset.
This also holds with the added requirement that the oscillator must be a single strict object.

On the other hand, as long as you are staying within the domain of two-state isotropic CA with Moore neighbourhood, there are only finitely many different CA where a given finite pattern is a phase of a nontrivial oscillator that is a single strict object.

This suggests some challenges/questions:

• Find a smallest possible pattern that isn't a phase of a single-strict-object nontrivial oscillator in any of the 2^102 two-state isotropic CA with Moore neighbourhood, measuring "smallest" by the population of the pattern.
• ... measuring by the MCPS.
• ... measuring by the bounding box area.
• Is there a finite pattern, such that there is precisely one two-state isotropic CA with Moore neighbourhood where the pattern is a phase of a single-strict-object nontrivial oscillator?
• Is there a finite pattern that is a phase of precisely one single-strict-object nontrivial oscillator (although that oscillator may or may not be endemic), as long as you are staying within the domain of two-state isotropic CA with Moore neighbourhood?

Create a pattern which can ensure that a block at the center remains intact after two gliders are fired at the pattern from any direction and position outside the bounding box of the pattern. It does not have to be able to survive multiple pairs, just any set of two gliders. This probably requires a sat solver.

IT IS NOT ISOTROPIC - "AN ISOTROPIC RULE" IS NOT "ANISOTROPIC RULE"!

also, I'm planning to make a project that supports Hensel notation, and infinite grid (Most of the Scratch projects only have a finite grid and only some of then supports life-like rules other than B3/S23) (I prefer kitten4.code.game to original scratch)

EDIT:

You cannot - Scratch allows only 300 clones (aka cells) on screen at a time

I use pen, instead of clones. If I must use clones, remember, there is something called TurboWarp.
Also I said, I use kitten4.code.game and it has no limit.

and even then there is a limit to the length of lists (aka arrays).

I planned to use tree instead of grid to store data. Again, I use kitten4.code.game and it has no limit.

Try to simulate an isotropic rule on Scratch.

A possible implementation: make a list with each element storing a list of x position of all on cells in the axis. If the first element contains anything, insert an empty element into the first place, pushing other elements down by 1 place. To check the amount and position of its neighbors, a cell checks if the element it's in, and elements of 1 index up and down, contains cell at position of x-1 to x+1, which x is the position of the cell itself.

Let me do it - just be aware that I won't implement displaying cells in first place. (EDlT) It could support anisotropic rules of any range, including range-1 isotropic rules as subset.

Done+Dusted. Tell me if I made any mistakes - the rules have to be inserted transition by transition, which makes mistakes easy.

Do Life-like rules count? If they do not, this task will be a lot harder as Life-like is a subset of isotopic.

No, even though it would be possible to emulate such rules in the finished metacell.
