Re: Thread for basic non-CGOL questions
Is there a known Isotropic Totalistic / Non-Totalistic rule that can be made to explode at a relativistic speed (speeds between c/2 and c) in all directions. By "be made", I mean that it is ok to specify a pattern, but it has to chaotically explode at a relativistic speed forever (Without any c explosions overtaking).
Kinda like this, but this still has some c replicators and it is eventually overtaken by a c explosion

How do B0 rules work without instanteaous filling up every cell in the plane? I just realised my current definition of naive rules would allow such behaviour (even though my implementation does not).

I just realised my current definition of naive rules would allow such behaviour (even though my implementation does not).
Golly wrote:Emulating B0 rules
Rules containing B0 are tricky to handle in an unbounded universe because every dead cell becomes alive in the next generation. If the rule doesn't contain Smax (where max is the number of neighbors in the neighborhood: 8 for Moore, 6 for Hexagonal or 4 for Von Neumann) then the "background" cells alternate from all-alive to all-dead, creating a nasty strobing effect. To avoid these problems, Golly emulates rules with B0 in the following way:
A totalistic rule containing B0 and Smax is converted into an equivalent rule (without B0) by inverting the neighbor counts, then using S(max-x) for the B counts and B(max-x) for the S counts. For example, B0123478/S01234678 (AntiLife) is changed to B3/S23 (Life) via these steps: B0123478/S01234678 -> B56/S5 -> B3/S23.
A non-totalistic rule is converted in a similar way. The isotropic letters are inverted and then S(max-x)(letters) is used for B counts and B(max-x)(letters) is used for the S counts. The 4 neighbor letters are swapped using the following table:
4c -> 4e
4e -> 4c
4k -> 4k
4a -> 4a
4i -> 4t
4n -> 4r
4y -> 4j
4q -> 4w
4j -> 4y
4r -> 4n
4t -> 4i
4w -> 4q
4z -> 4z
A totalistic rule containing B0 but not Smax is converted into a pair of rules (both without B0): one is used for the even generations and the other for the odd generations. The rule for even generations uses inverted neighbor counts. The rule for odd generations uses S(max-x) for the B counts and B(max-x) for the S counts. For example, B03/S23 becomes B1245678/S0145678 (even) and B56/S58 (odd).
A non-totalistic rule is converted in a similar way. For even generations invert both B(x)(letter) and S(x)(letter). For odd generations except 4-neighbor letters, use B(x)(letter) if and only if the original rule has S(max-x)(letter) and use S(x)(letter) if and only if the original rule has B(max-x)(letter). For 4-neighbor isotropic letters use the table above. For example, B0124-k/S1c25 becomes B34k5678/S01-c34678 (even) and B367c/S4-k678 (odd).
For a MAP rule B0 is equivalent to the first bit being 1. Smax is equivalent to the 511th bit being 1. For B0 with Smax the rule is converted to NOT(REVERSE(bits)). For B0 without Smax the even rule is NOT(bits) and the odd rule is REVERSE(bits).
In all cases, the replacement rule(s) generate patterns that are equivalent to the requested rule. However, you need to be careful when editing an emulated pattern in a rule that contains B0 but not Smax. If you do a cut or copy then you should only paste into a generation with the same parity.

Re: Thread for basic non-CGOL questions
A 3c/4 frontend alternates between moving ahead by a full diagonal (due to B1c) and a half diagonal. The only way to move faster is to have 2 full diagonals, but this means that B1c is on in both even and odd generations, meaning that the rule explodes at c.
Without B0, we can only move a half diagonal per generation, which is why c/2 is the fastest diagonal speed for non-B0.

Any sufficiently advanced software is indistinguishable from malice.
