Soup search results

[David]

I've discovered new xs23:

Code: Select all

x = 16, y = 16, rule = B3/S23

ob2o2bo2b2o$2ob3obo2bob4o$b6obob3o$bobo3bobobo2bo$o3bobobo2bobo!

Why isn't this recorded as my discovery, in Catagolue?

While not technically from the soup search, a component to turn a block into a fuse w/two tails:

Code: Select all

x = 21, y = 31, rule = B3/S23

Even though this particular conversion is rarely needed (since the ftt can be easily made from a tub w/tail, which can then be made from an eater), it will come in handy in cases where turning a block into a tail-first eater is awkward.

This p2, while common in diagonal symmetries like D2_2, hadn't occurred until it showed up in one of my hauls:

This isn't listed as my discovery, either... Why?

Only discoveries sufficiently notable to appear on the Twitter feed are attributed. Otherwise, user pages would soon become clogged with tens of thousands of so-called 'discoveries' which are no more than trivialities.

Yesterday, Apgsearch reported the following new P15 "oscillator", a fumarole on pentadecathlon: http://catagolue.appspot.com/object/xp1 ... 0757/b3s23
This appears to be a pseudo-object rather than an actual object, so I suspect apgsearch's pseudo-object filter may be buggy. I am aware of 3 ways in which a fumarole and pentadecathlon can interact non-trivially, but this (#4) isn't one of them. (There are 3 (EDIT: 5) additional pseudo-objects where the pentadecathlon spark inducts the fumarole's stator).

This appears to be a pseudo-object rather than an actual object, so I suspect apgsearch's pseudo-object filter may be buggy.

It was decided in the creation of apgsearch that oscillators whose histories overlapped/touched should be counted as one object.

One reason for this is that otherwise, it would be possible for (say) a pseudo-object consisting of two reflectorless rotating oscillators to have an overall period of 40, but for each of its components to have period 80. And I'm not sure what this should be counted as.

In theory, using a three-dimensional array (x, y, t) we could distinguish between objects that do not causally affect each other, despite occupying the same space at different times. But Golly doesn't support 3D rules (yet?) so I would have to resort to implementing this manually (which would be awkwardly slow).

One way to avoid the above specific problem is to attempt to split an pseudo-object candidate into two objects, and if one (or both) have the same period as the combined candidate, this is a trivial composition, but if both have lower periods (e.g. 40 and 40 vs. 80), this should be included as a new non-trivial object. (I have a custom rule with a small but prolific P280 (mod 90) rotating shuttle; 2 in the same arena make a P140 oscillator.)

In theory, using a three-dimensional array (x, y, t) we could distinguish between objects that do not causally affect each other, despite occupying the same space at different times. But Golly doesn't support 3D rules (yet?) so I would have to resort to implementing this manually (which would be awkwardly slow).

The pseudo-still-life filter I use with my still-life/oscillator searcher does use a 3-dimensional array. It checks cell connectivity and cell viability, but does not actually run patterns.
