Re: Up-to-date conduit data for Hersrch

Any thoughts on shipping Windows/Mac/Linux versions of this with Golly, and hopefully some other search utilities as well? It would be nice to have gencols, ptbsearch/catalyst, dr, etc. in working order, right along with Golly or as an optional package of some kind. Golly scripts could be used to m...

Re: Geminoid Challenge

Is there a non-KISS reason to limit yourself to having only 1 live "hand" object at a time? Suppose you've found a recipe that builds an object of interest and leaves two spare blocks. Construction could continue using one of these blocks as the "hand", and then return later to continue with the oth...

Without max-live and/or max-active I think that search will take a very long time to run.

Re: Incomplete search patterns - try to complete

I have already tested out this wick and there's no solution! That's a bold statement. I doubt Bellman could prove this in a reasonable time. I imagine you had max-live and max-active parameters set, which will have excluded most of the search space from consideration; all you've proved is that ther...

Re: Snark-based still-life glider duplicators

I currently use MinGW for most things. That's a g++ port for Windows that uses Microsoft libraries (so no need to mess with Gnu library licensing issues). Since the compiler is the same, it should provide less porting issues. I could try to give it a shot (although responses may be slow, as I'm not...

That has to be the most useless accidental discovery I have ever seen. Why use an exotic palladium catalyst when you can just use THF and NaOH? Personally I tend to agree.

Re: Bellman

At its most active, 9 cells of the eater3 differ from its stable state. This happens twice: once when the loaf has been flipped over and is starting to interact with the pre-block, and again 2 generations later. So max-active needs to be at least 9 to find an eater3. One way to investigate questions...

Re: Scratch Your Heads: Glider Synthesis of Bellman One

Bear in mind that not all the cells of the still life interact; as a result there are many possible patterns that can catalyse the reaction in the same way. Bellman outputs partial patterns that describe only the catalytic portion of the still life. The partial pattern for the AK-94 catalyst looks l...

Re: Thread For Your Accidental Discoveries

Nice! It looked like it might be possible to turn it round a corner with the pi-heptomino reaction, but it doesn't quite work - the pattern interacts with the new blinkers before the pi-heptomino is produced. EDIT: Two of them can interact and suppress each other's debris: x = 14, y = 60, rule = B3/...

Re: Geminoid Challenge

What we really need for the Geminoid is a set of four slow-salvo constructions, one from each direction. With "Blockic" techniques it's probably possible to construct an isolated snark reflector with a slow salvo, but this would be quite large and complex, and wouldn't really allow for other pattern...

All you need to stabilize ak-47 is to eat a traffic-light from far enough away to avoid the main engine. It seems like there should be a way to collide either a block or blinker with a traffic light and then use a catalyst to convert the explosion back into just the original block or blinker (at th...
