Soup search results

The newest cuphook variant is formed in a synthesis-friendly way:

Apparently this happened four days ago, but I've been too immersed in other things lately to have noticed it:

That is to say, two new p8 oscillators have appeared in the last couple of weeks.

The fun stuff is starting to appear now that we're churning through 10^12 objects per week. There are currently 30k distinct objects, and the power-law appears to be approximately:

"Searching 5 times as many soups yields twice as many distinct objects"

It's true going from Achim's census up to Okrasinski's, and has remained true up to the current status of Catagolue. So I expect around 60k distinct objects once we've reached a total of 50 * 10^12 objects (some time in early 2016, I guess).

A quite compact seed for an eater 2:

Unfortunately, it ends up in the middle of the reaction envelope. This one is more edge-shot, though (cleanup seed not included):

So what's the next likely new period for Catagolue? Any bets on whether it will be an unknown oscillator next time?

If you're talking about asymmetric soups, then I would bet it's going to be period 24, namely a figure eight on pulsar.

Not surprisingly, I has been right http://catagolue.appspot.com/object/xp2 ... 81qo/b3s23

[Kazyan]

Good stuff in the last two hours. I'd actually call the new 13-bitter a "python bridge snake" from the precedent set by this 12-bitter. As for the last holdout, here's the progression of snakes as of the /textcensus I just opened:

"xs6_bd","186617512"
"xs7_3lo","7903060"
"xs8_31248c","2604680"
"xs9_31248go","99964"
"xs10_wg853z65","2008"
"xs11_xg853zca1","205"
"xs12_358gzy012ko","22"

Exponential regression and extrapolation suggests that the Jormungand (everyone else is giving it their own pet name, so I'll hop on board too) should have shown up around the 7.660 trillion object mark. The current expected value for the number of them in Catagolue is 1.167 or so, so nothing's particularly weird yet.

I'll guess too: maybe period 10 will be next, like a furamole and bipole, or period 12, like a mold and jam.

[codeholic]

I bet it's going to be figure 8 on pentadecathlon, i. e. period 120.

[biggiemac]

Assuming independence to first order, a compound oscillator will occur with frequency proportional to the product of its constituents. For reference, the frequencies of a few common oscillators normalized to let pulsars have unit frequency:

Pulsar: 1
Pd: 0.01
Figure-8: 0.0004
Mold: 0.0002
Jam: 0.00002

So we have pulsar+pd estimated 40 times more likely than pulsar+figure-8, but even the latter is 100 times more likely than pd+figure-8. Given we only have 4 cases of pulsar+pd, I'd say the statistics aren't on our side to see the pd+figure-8 anytime soon. My estimate is we would need to increase the census by 2 to 3 orders of magnitude.

The compound-oscillator piece missing from this is the candelfrobra, because it needs an inductor. A candelfrobra-on-beacon has occured twice, and a beacon has frequency 10 on the scale above. A candelfrobra-on-mold, a trivial p12 oscillator, could be expected if we increased the census by 4 to 5 orders of magnitude.

We have 20 occurrences of p46 objects, putting them at frequency 0.0000003. To my knowledge, there isn't any interaction possible between a twin-bees shuttle and a pulsar, but there is with a pd. We might uncover a whopping p690 with an additional 7 to 8 orders of magnitude.

I would certainly hope the next period is p7 though. 28p7.2 looks like it should be not too far from possible with a couple more orders of magnitude - though C2_2 symmetry isn't nearly as big of a frequency boost as, say, D2_1 (see all natural still lives with 38 bits or more.. for reference the largest natural C2_2 object in the C1 census is currently 32 bits, and the largest that regularly forms from C2_2 explosions within the soup is 30 bits)

Time will tell!

That's probably reasonable, not least because these oscillators tend to appear piecemeal.

For reference, the frequencies of a few common oscillators normalized to let pulsars have unit frequency:

I like how the jam is now considered to be a common oscillator!

So we have pulsar+pd estimated 40 times more likely than pulsar+figure-8,

By which you mean 25?

My estimate is we would need to increase the census by 2 to 3 orders of magnitude.

Wow. Extrapolation suggests Catagolue should easily cope with growing 2 orders of magnitude larger, but I might have to auto-delete old hauls to economise on storage space (it's using about 4 gigabytes at the moment).

We have 20 occurrences of p46 objects

That many already? Wow, I can remember back when p46 objects were nowhere to be seen, apart from a report that Achim had found one in a large toroidal soup.

We might uncover a whopping p690 with an additional 7 to 8 orders of magnitude.

My int64s would overflow at that point...

I think that Gosper guns would be much more common, since you only need two incomplete p30 shuttles (i.e. ones which lack a block). As for Simkin guns, I have no idea what the expected frequency is.

I would certainly hope the next period is p7 though.

Hopefully, and realistically, in the form of a loafer.

Time will tell!

Only if we generate lots more soups. We'll probably reach about 30 * 10^12 objects by the end of 2015, and 100 * 10^12 objects by the end of 2016, unless we can vastly increase engagement (e.g. by making that cryptocurrency built on top of apgsearch).

Here's a fairly simple phoenix synthesis:

I built it by noticing that the glider + block collision to make 2o$2b$ob! sparks can be looped to make oscillators.

[biggiemac]

For reference, the frequencies of a few common oscillators normalized to let pulsars have unit frequency:

I like how the jam is now considered to be a common oscillator!

I mostly included it because the prior post had mentioned it. I didn't include fumarole as common though.

So we have pulsar+pd estimated 40 times more likely than pulsar+figure-8,

By which you mean 25?

Math-after-midnight! My bad

I think that Gosper guns would be much more common, since you only need two incomplete p30 shuttles (i.e. ones which lack a block). As for Simkin guns, I have no idea what the expected frequency is.

Incomplete but fully synchronized. I'd imagine the yl_120 is more common than GGG by multiple orders of magnitude, but even then the common Herschel path leaves only a few dozen generations in which to fortuitously edge-construct the last two blocks.

[praosylen]

I would suggest that a 2-SE puffer will be the next unusual object to occur. If you look at the statistics, about 5 million stabilized SE's have occurred in about 9 trillion soups, suggesting a frequency of 1 in two million. This means that theoretically, two switch engines have occurred in at least 2 soups already. The chances of them being in the same direction and adjacent to each other is something that I don't know how to estimate, though. I would say that it's likely that one will appear within the next few tens of trillions of soups.

[mniemiec]

Here's a fairly simple phoenix synthesis: ...

This was the most optimum Phoenix synthesis for over a decade, until very recently.You should have a look at at my object synthesis web site http://codercontest.com/mniemiec/lifepage.htm. It is about a year or two out of date (as there has been such an explosion of activity recently, and I haven't been able to keep up with it in real time), but it has around 11000 syntheses, most of which are boring, but also many of which can give insights into other syntheses.

Looking at it more carefully, it appears it's a normal glider producing switch engine that gets hit by a glider after its been going for a while, at generation 24263.

The effect propogates inside its active region, but it survives. Just a miscategorization, nothing to see here.

Anyone know what causes this specific sort of miscategorization?

[Kiran]

In generation 40000 it looks like a normal glider producing switch engine and everything else is stabilized, there are two perturbations produced by gliders but both are temporary.
