Anyway, flipper77, you said you've only ran 15 000 000 soups with symmetry. How many soups has Lewis Patterson simulated? (I'm trying to get a confidence interval for the frequency of this object in symmetric soups, although it's difficult to extrapolate meaningful information from a single event.)...

A 31-bit still life should show up every 20 billion still lifes or so, except that there's that awkward bias against odd-bit-count still lifes. Maybe not coincidentally, I haven't actually seen a 31-bitter yet. In the text file you posted, the still life " xs31_69b88bbgz69d11dd " has four occurrenc...

Soup produces P2 similar to the 19-cell still life "mango with block on dock" but with a beacon: x = 16, y = 16, rule = B3/S23 bobo3b6ob2o$bo5b4obo$o2b2ob2o5bo$ob3o2b2obobob2o$bobob3ob2o2b3o$o4b2ob 2o5bo$4b2o2bo2bobobo$2bob2ob2ob4obo$2bob3ob2ob2o$2o3bobob4o$2ob2o2bobo b3o$b2obo2bo4b3o$b2ob2ob2obo3b2...

I ran the script posted above and the only unsolved still life it detected was #116 from a symmetric soup: x = 16, y = 16, rule = B3/S23 bo2bo6bo2bo$ob2ob2o2b2ob2obo$o2bo8bo2bo$obobob4obobobo$2ob2o2b2o2b2ob 2o$o3b2ob2ob2o3bo$bob2o6b2obo$3bo2bo2bo2bo$3bo2bo2bo2bo$bob2o6b2obo$o 3b2ob2ob2o3bo$2ob2o2b2o...

Not strictly natural, because I found it by adding symmetry options to apgsearch, but this 2-engine switch-engine variation happened (the program calls it ' yl576_1_246_756156edd5c2c10ac5bc316e7c8f38ef '): x = 18, y = 18, rule = B3/S23 bobobobo4b3o2bo$o2b2o9bob2o$7b5ob5o$2o4b4ob2obobo$bo3bobo4bobo2b...

WOW... You must've searched a LOT to find that on soup searches... Did you tweak the source code to make symmetrical soups? Yep, I changed it so it generates soups with a line of symmetry through the middle. It also found this P4 oscillator which I've never seen mentioned anywhere before: x = 16, y...

4 blocks + some junk -> twin bees shuttle variant (amongst other things): APGsearch doesn't properly detect this, it just labels it as 'OVERSIZED'.

Two blocks + four stairstep hexominoes -> P6 A for All (+ loads of other stuff): x = 16, y = 16, rule = B3/S23 3bo8bo$3b2o6b2o$4b2o4b2o$5bo4bo4$2o12b2o$2o12b2o4$5bo4bo$4b2o4b2o$3b2o 6b2o$3bo8bo!

I think that the wickstretcher should be identified properly (can you confirm?), although instances of the 'same' wickstretcher with different backends may end up with different representations. (This is a feature, not a bug!) I think it only identifies different back ends to wickstretchers if they...

It's been posted before, in this topic, I think that's the earliest known mention of it.

Here's a P4 oscillator in B3/S3 (the only non-p2 thing I've found so far): EDIT: this topic might be better moved to the 'other CA' sub-forum?

Wow! How many soups have you been running?! Not that many, really. The script kept crashing occasionally (I think the problem was already brought up by someone else in the apgsearch thread) so I ran it for about an hour or so. Not sure how many soups that is, but it counted 153 occurrences of the p...

In B36/S0245 using seed "2014-09-18T15:53:57.851000_wm", in soup number "144768" a pathological object is detected, but the ash is in fact quite mundane. The sanity check at the end of linearlyse is included in my apgsearch but it is this a related issue? Soup rle: Urgh. I have no idea why this is ...

New (?) P6, c/3 orthogonal spaceship in B3678/S24678 (It's not listed on the database anywhere) :

I've also noticed in 23/35 that the P2 Washing Machine occurs occasionally (about half as frequently as the pulsar), but as far as I can remember it hasn't been seen in regular Life: x = 16, y = 16, rule = B35/S23 o7b4o2b2o$o2bo4bob3obo$bo2bobo2bobo$bo2bobo2bobo3bo$2bob3o2b2obobo$4bo bobo2bobo$2b4ob...

It will also be good to have a way to retrieve the source soup for any unusual still life or oscillator (not just the top 50 or 100 highest scoring). Maybe we could add another column into the census table, which lists the seed/number for the first soup which generates each pattern (a bit like the ...

I've got a variation of ExpungeObjects which gets rid of both 2-cell objects now working, that's brought the speed up to about 100 soups per second which is a massive improvement. Interestingly, the 23/35 script I've been using didn't use any ExpungeObjects rules, and after adding it back in there d...

For 2x2, can you give readouts of qlifetime, ruletime and gridtime to see where the bottleneck lies? (These are printed in brackets when the script finishes.) 10000 soups processed in 259.699044811 (14.7483, 4.64597, 236.95079) secs.

Run it in CoalesceObjects for at least the entirety of its period. 'lpop' is the number of cells in state 1, and 'llength' and 'lbreadth' are the dimensions of the box bounding the state-1 cells. 'dpop' is the number of cells in state 2, and 'dlength' and 'dbreadth' are the dimensions of the box bo...

Just out of interest, is there much of a market for searching other rules? I'm not sure; I've done fairly extensive searches in other rules before but I don't think anyone else has ever expressed interest in it at all. However, back when the Soup Search was up and running on here, the other rules s...

Just realised that some of the things the program marks "split rotor, gap = 1" are oscillators which require both parts to work. I'd been skipping over them under the assumption that they were just trivial cases of two smaller oscillators near each other. I couldn't find the following two oscillator...
