I saw a post about that before but can't find it nowAforAmpere wrote:What are the speed limits for spaceships in B0 rules? Orthogonal is C. I think, but I am not sure that the diagonal speed limit is 3c/4, but what about oblique?
Well, I thought about it for a bit, this pattern should determine the speed limit, as this expands the fastest possible in all directions, while only half the generations use B1c, to allow spaceships.Majestas32 wrote:I saw a post about that before but can't find it nowAforAmpere wrote:What are the speed limits for spaceships in B0 rules?

o!
Hold on. If m=n, then the case reduces to a diagonal, or 3(m,m)c/2(m+m). Consider the ship with a diagonal speed of c/3 (the diagonal speed limit). Then 3(m,m)c/2(2m)=c/3.Majestas32 wrote:3(m,n)c/2(m+n). Which leads to another question: what's the knightship speed limit in rules where the diagonal speed limit is c/3 (like movostill 3)?
You can’t apply the formula to that, the formula only applies to the B0 rules.Gamedziner wrote: 3(m,m)c/4m=c/3
9(m,m)c/4m=c
9(m,m)c=4mc
9(m(1,1))c=4mc
9m(1,1)c=4mc
(1,1)c=(4/9)c
(1,1)=4/9 (contradiction)
You could always do what I did and steal one from a page that already has one.gameoflifemaniac wrote:How to add a LifeViewer window on a LifeWiki page?
Take a look at B2-a345678/S012345678 (I stole this proof from somewhere but I don't remember):Majestas32 wrote:what's the knightship speed limit in rules where the diagonal speed limit is c/3
It's more complicated than that: B2e (for most but not all other transitions) and S5a (for sufficient other transitions) also allow (a,b)c/(2a+b) speeds.Majestas32 wrote:(a,b)c/(2a+b), S4w
(a,b)c/(2a+2b), ~B2a/~S4w
Template:EmbedViewer might be helpful. If you need more flexibility, you can also use LV:Viewer directly and add the appropriate styling.gameoflifemaniac wrote:How to add a LifeViewer window on a LifeWiki page?
The original form of the P45 glider gun might be what you're looking for -- it's kind of borderline between elementary and engineered, but statorless in any case.Rhombic wrote:How can we look for both a small engineered and an elementary statorless gun in CGoL?
It seems more than feasible enough in both cases!
I vote in favor of that (personally I'd nominate AbhpzTa's adjustable spaceship rule)A for awesome wrote:Also, on an unrelated note, I've been thinking that it might be worthwhile to have a yearly competition modeled off of Pattern of the Year, but for other cellular automata -- it seems like OCAs are a major component of what's going on on these forums that doesn't get enough recognition. I'm kind of curious what everyone else thinks about that. Maybe like an "OCA Pattern of the Year" or "Rule of the Year" competition, or combined into "OCA Development of the Year"?
I agree with that idea as well, it would show all the other progress in these forums.A for awesome wrote:Also, on an unrelated note, I've been thinking that it might be worthwhile to have a yearly competition modeled off of Pattern of the Year, but for other cellular automata -- it seems like OCAs are a major component of what's going on on these forums that doesn't get enough recognition.

#C [[ AUTOFIT HISTORYFIT ]]Good work there, you've almost got it. The "if count > 15 then break end else break end" is a clue. Basically, you're not doing anything different if your count test succeeds. Also, you're only breaking out of the inner while loop, but there's no way for the program to know that it should break out of the outer while loop.gameoflifemaniac wrote:EDIT: ...
