Re: soup searching an 8x8 grid
I thought I remembered Mike Playle doing some searches for asymmetrical agars on toruses, I forget what size, with some interesting higher-period results. All I can find on a search is these two posts . Was that someone else who did those searches, or am I somehow missing the relevant posts? Yes, t...

Re: INFORMATION to INTELLIGENCE
Absence/presence of blocks spaced 2 cells give us a density of 1 bit / 16 cells, and this seems like the maximum density that can be achieved with a static pattern. Tubs, boats and ships give 8 possible states (3 bits) per 25 cells, or about 1 bit / 8.3 cells: x = 18, y = 18, rule = B3/S23 bo4b2o3b...

Re: Thread for your chaos-edgeshooting reactions that can probably yield new conduits
Speaking of only having two ∏→∏ conduits, how do we not have a PF30 conduit (extracting the ∏ that already forms in the ∏-heptomino's evolution 30 generations later and 9 cells ahead)? Well, there is this thing: #C pi-heptomino conduits: Dean Hickerson, 17 February 1997 #C Herschel-to-pi stage by P...

Re: Agar discussion thread
Has anyone thought about how to define apgcodes for agars and wicks? I'm approaching 80,000,000,000 soups in T29x33 and I've got quite a few duplicates. I can assign apgcodes to the bounded patterns that crop up, but I'd like to do something similar with the unbounded ones. They don't have bounding ...

Yes - they do interact on their own, don't they? It just takes a couple of cycles for them to get there. Doh.

Re: Agar discussion thread
Yup, it's easy to construct agars with arbitrarily large periods. What about naturally occurring ones, though? The other day I found this one, which appears to be p9440 on the face of it, though it's actually only p590 if you take the symmetry into account: #CXRLE Pos=0,0 Gen=0 x = 31, y = 32, rule ...

I figured that I therefore might be able to get some useful advice for you, like how to sort through all of the ideas and figure out which are the most practical.

Re: Soup search results
I had a hunch that there might be interesting things lurking in the non-square toroids, which I haven't heard of anyone trying to search before. I wrote a basic searcher that runs on an FPGA. It chooses random soups, runs them until periodic, throws out all the p1s and p2s, and reports the rest to s...

Wouldn't that only rule out gutter symmetry? There is a live stator cell in the gutter immediately below the two central rotor cells. It remains live throughout, despite the cell above it both living and dying. This can only happen if it has exactly 2 live stator neighbours. In a symmetrical config...

There's also the #P syntax -- "P" | "R" ; top-left corner coordinates -- but that also hasn't seen much of any use except maybe in Xlife. Bellman's input files use the #P syntax.
