Re: Oscillator search programs in other rules

I had an idea for automatically building objects with LLS. First, I generate or find a working section of a partial. Then I feed into LLS a searchfile to expand that partial. If it returns UNSAT, go back. Repeat until it finds a complete object with the required properties. Here are some details fo...

Re: Spaceship Discussion Thread

Sorry for my noobiness at spaceship searches (I don't use search programs other than apgsearch), by why are spaceship searches done by width? It means you can treat spaceships as lists of rows satisfying certain 'local rules' (in the case of the (2, 1)c/6 search, each of these rules only mentions 7...

Re: Soup-based syntheses

(I sure wish Catagolue/Shinjuku had an audit trail so that "whatever was there before" is visible. Sometimes that's useful information, which is why it's so helpful that Mark Niemiec's database keeps multiple recipes.) (While I'm wishing, naturally the audit trail should include who uploaded what w...

Re: Oscillator Discussion Thread

lack of stator I didn't even think about that. This is the first strictly volatile p16. Also, it seems to merely be bad luck (rather than necessity) that it doesn't glide-reflect instead of staying in the same place. If it moved one cell each half-period, it would have been hilarious (front-running...

Re: Oscillator Discussion Thread

A for Awesome noticed that rliston's G1 searching turned up something new today: this new p16 oscillator. It breaks both the minimum population and bounding box records for a p16 oscillator. It has a few weak sparks, so it will probably give some smaller LCM oscillators, although I'm not sure if it...

Re: Thread for basic questions

Can a p4 with one cell period 4 rotor exist? Not in any two-state rule. If there's only one cell changing, and it can only be either 0 or 1, then there's no way you're getting above a P2. You need at least two changing cells to hold enough information to get to p4. (Am I answering the right questio...

I want a page that combines the results of C1 and G1. There's been important discoveries in each of them recently and I kind of want an overview.
Is it okay if it's infrequently updated (say, every 24 hours or so) by automatically combining the C1 and G1 censuses?

Re: Synthesis of gliders using other spaceships

Citation needed for your last paragraph: a pair of 2ECs has 96 different relative phase combinations, compared with only 6 for a pair of Sir Robins, so I'd have guessed 2ECs would have more distinct collisions.

Re: [Nonsense Writing] interpret GoL facts as real life facts

Hmm, that's surprisingly accurate. An animal cell is about 20um in diameter, so a cluster of 10^6 cells should be around 2 mm. Eleven of those would yield something about 22mm long and 2mm in diameter, which is consistent with a small caterpillar. In fact, there are almost certainly real-life caterp...

Wait, so it doesn't commit old, uncommitted hauls? That is a problem by itself... It's subtler than that.
