Re: Results of catalyst tests

Post by Scorbie » November 28th, 2015, 10:07 pm

I once ran a series of tests of optimal forms of catalysts, but unfortunately, lost the data. I put the results into account when I was running the tests, though. The polymers you see on the results are the results from then.

Anyway, after that loss of data, I decided to post and update optimal catalyst forms here.

1. Boat vs Barge
  • Run time comparison (1000 soups run)
    I'm still not sure how I should interpret the data, though.
    Should I compare the 'real' time or the 'user' time?
    Which of the two is more meaningful? The difference or the ratio?

    Code: Select all

    boat
    real    5m46.317s
    user    5m0.536s
    sys     0m2.108s
    
    barge
    real    4m8.638s
    user    3m2.784s
    sys     0m2.144s
  • Result:
    Boat - Barge = 51 reactions / 1000 soups
    Barge - Boat = 6 / 1000
And an interesting reaction. Only works with the barge:

Code: Select all

x = 16, y = 6, rule = B3/S23
3o3b3o$obo3bobo$3o3b3o4bo$12bobo$13bobo$14bo!
2. Regenerative loop monomer vs dimer (1000 soups)

Code: Select all

x = 31, y = 9, rule = LifeHistory
25.2A$4.2A18.A2.A$.2C2.A15.2C2.A.A$C.C2A15.C.C3A.2AC$C4.3A12.C9.C$.C
2A4.A12.C2A.3AC.C$3.A.3A15.A.A2.2C$3.A.A17.A2.A$4.A19.2A!
  • Speed comparison
    Unfortunately I accidentally closed the console after the search so I couldn't remember the exact values, but it was about 30m (monomer) vs 20m (dimer).
  • Result comparison
    Monomer - Dimer = 3 / 1000 (The three were all due to steric hindrance. I didn't count junk noise; i.e. rock-tub reactions from the monomer form.)
    Dimer - Monomer = nothing
Well, I decided that the difference of speed is big enough and the difference of results are small enough to just use the dimer form.

3. Eater 5 monomer vs dimer (1000 soups)

Code: Select all

x = 24, y = 12, rule = LifeHistory
.2A3.C5.2A3.C$.A3.C.A4.A3.C.A$2.A3.2A5.A3.2A$3.A10.A$.A.5A4.A.4A.A.2A
$A.A4.A3.A.A4.2A.A.A$A.A.3A4.A.A.2A4.A.A$.2A.A7.2A.A.4A.A$20.A$16.2A
3.A$16.A.C3.A$17.C3.2A!
  • Run time comparison:

    Code: Select all

    monomer
    
    real    30m31.850s
    user    27m40.392s
    sys     0m3.860s
    
    dimer
    
    real    30m43.314s
    user    28m20.192s
    sys     0m3.604s
The speed of the two are pretty much the same, so I'm gonna stick with the monomer form. The results was set(dimer).issubset(set(monomer)), in case you are interested.

4. Ship+Eater variant monomer vs dimer (100 soups)
I decided to check only 100 as it took too much time.
  • Run Time:

    Code: Select all

    Monomer
    
    real    5m59.286s
    user    3m15.944s
    sys     0m0.432s
    
    Dimer
    
    real    4m29.057s
    user    2m38.988s
    sys     0m0.376s
    
So the dimer is faster. Also there were no difference between the two, so I think I can safely use the dimer form.\

5. The "rock eater2" monomer and dimer1 (100 soups)

Code: Select all

x = 37, y = 14, rule = LifeHistory
.A19.A$A3.2A14.A3.2A$.A3.A15.A3.A4.2A$2.3A2.2C.A11.3A2.2C2.A$7.2C.3A

3.A$8.2A.A16.A.A2.4A$8.A.2A17.A.A$31.A.2C$30.A2.2C$30.2A!
  • Run Time:

    Code: Select all

    monomer
    
    real    5m9.183s
    user    2m40.544s
    sys     0m0.768s
    
    dimer1
    
    real    4m5.780s
    user    2m11.356s
    sys     0m0.480s
    
  • Resuts:
    monomer - dimer1 = 5 / 100 due to steric hindrance, but three are trivial reactions that are filtered by eater2, so I would say 2/100.
    dimer1-monomer = None.
5'. two rock eater2 dimers (100 reactions)

Code: Select all

x = 42, y = 14, rule = LifeHistory
.A22.A$A3.2A17.A3.2A$.A3.A4.2A12.A3.A$2.3A2.2C2.A13.3A2.2C.A2.A.2C$7.
2C.A19.2C.4A.2C$10.A.A$5.4A2.A.A14.4A.4A.4A$5.A3.2A2.A14.A3.2A2.2A3.A
$8.A2.2A3.A12.2A8.2A$8.A.A2.4A14.7A.A$9.A.A19.A2.A2.A.A$11.A.2C23.A$
10.A2.2C$10.2A!
  • Runtime:

    Code: Select all

    dimer2
    
    real    4m19.534s
    user    2m27.636s
    sys     0m0.400s
    
    dimer1
    
    real    4m2.582s
    user    2m11.540s
    sys     0m0.452s
    
    
  • Results: the second dimer form has 3 nontrivial reactions not found in the first form. Two of them can be filtered by an eater2 which makes 1/100. I didn't check the first form - second form as I am going to use the first form anyway.
6. drifty_twit, monomer vs dimer
I'm not sure how this is similar to a twit, but something sure does filter this. The frequency of this is very low, about 0.01. This is currently classified as uncommon.

Code: Select all

x = 38, y = 13, rule = B3/S23
28b2o6b2o$27bobo7bo$5b2o20bobob2ob3o$5bobo20bobobobo$7bo22bobo$3o4bob

3bobobo18bobobobo$b3ob2o17b3ob2obobo$o22bo7bobo$2o21b2o6b2o!
  • Speed

    Code: Select all

    monomer
    
    real    7m9.915s
    user    3m33.728s
    sys     0m0.676s
    
    dimer
    
    real    5m19.030s
    user    3m8.820s
    sys     0m0.424s
    
    The dimer is pretty much faster than the monomer form.
  • Results:
    Monomer - dimer = 4 / 100 which is pretty big, considering the actual frequency.
I'll just gonna use this form that can happily accept all reactions from the monomer form:

Code: Select all

x = 17, y = 11, rule = B3/S23
5b2o3b2o$5bobobobo$7bobo$7bobo$4b2obobob2o$5bobobobo$5bobobobo$3bobobo

I wonder about the twit eater without the tail:

Code: Select all

x = 14, y = 11, rule = LifeHistory
8.2A$8.A.A2$6.3A2.A.A$13.A$.2A3.C3.2A$.A3.C.A$2.A3.A$3.A$3A$A!
Although I can't find any promising catalyses right now, that doesn't mean there aren't any.

Will check in the next run, but I doubt it's going to be likely.

EDIT: Uploaded the source on Github at https://github.com/Scorbie/ptbtest.
Currently it's not so flashy but I'll gradually add content as I learn git, especially documentation.
In the meanwhile, you can view the docs of the old version here:

Okay, Finally! I finished writing the documentation for ptbtest! I can't believe that took three hours...
Guys, if you're interested, take a look and don't hesitate to ask questions. I hope you guys get to use this and run your own tests as well! I may put my hands off this project for now.

Just a self reminder of the seemingly optimal catalyst form:

I would like to propose the blinker+eater phase-changing reaction featured in 50P35, Pre-pulsar shuttle 47, and the recently discovered P13 oscillator, with an example catalysis:

Code: Select all

x = 19, y = 7, rule = B3/S23
11b3o3b2o$5b3o3bobo2b2o$11b3o2b3o$2b2o$bobo$bo$2o!
It may be beneficial to gather more data about it, and work out the general form of the catalyzing reaction.
Still drifting.

If that can be solved then this might or might not be useful in the gun collection that I am being lax about maintaining.

A potentially useful period-2 catalyst consisting of a fox and clock was found by Goldtiger997 on 14 Mar 2020 in an attempt to find a period-2 bumper:

Code: Select all

x = 18, y = 17, rule = B3/S23

It was noted at some point (not sure where, originally) that this reaction can delete a beehive:

Code: Select all

I suspect there are other uses for this catalyst.

Let's figure out the rules for using it.

The two cells closest to the p2 catalyst must each only have two neighbors. If either has three neighbors, then it will die right after the interaction begins, so cells born during the interaction will not die of overpopulation when they should (especially if the right cell of the leading edge dies too early) and will instead destroy the oscillators. In addition, if there is a line of two cells to the right and below the leading it (as in the pond and one of the orientations of the loaf), then after cells are born during the interaction, it will become a line of four cells that will birth more cells that will cause problems.
Now that that has been figured out, here are more examples of successful catalyses.

Code: Select all

x = 54, y = 67, rule = B3/S23

So it either is beehive-like or snake-like in gen 1, interesting.

In a lot of cases — but not all cases — it's probably equivalent to a BTS or the more versatile drifty eater 3. The clearance would probably be better with a better sparker (and there's nothing that says the sparker has to be p5, it's just the one I found it with).

(NOTE TO PEDANTS: Just because the example pattern shows it catalyzing a spark doesn't mean sparks are the only thing it can catalyze)

Awesome! That goes into Current News on the wiki, even if the fourth natural loafer didn't make the cut.

Unfortunately it doesn't have the kind of clearance needed to clean up the old F/Fx349P15, which turns a Herschel into a queen bee and then into an R pentominoes, or rather two mirror-image ones:

Maybe modern technology can rescue those pre-R reactions and make them into some other kind of output signal? It would be nice to have another mirror-image signal splitter to go along with the pi-to-2G one.

I feel like this is one of those catalysts which we've been looking for for years, and now that it's here, we're not quite sure what to do with it. Congratulations on the find!

Well, every new catalyst opens up new catalysis options. I'd recommend that you search for new conduits using this, mostly because most of the time I have basically no idea what I'm doing with conduits. Most of the conduits I have completed so far were due to sheer dumb luck, which I don't get very often. :P

Here's a derived "beehive chain" catalyst that should be occasionally and unpredictably useful:

Code: Select all

x = 21, y = 24, rule = B3/S23
8b2ob2o$9bobo$4b2obo5bob2o$3bobob2o3b2obobo$2bo6bobo6bo$3b6o3b6o$3o15b
3o$o3b3o7b3o3bo$b3o2bo3bo3bo2b3o$4bo4bobo4bo$3bo5bobo5bo$3bobo4bo4bob
o$4bobo7bobo$5bo9bo$10bo$9bobo$9bobo$10bo2$10b3o$9bo3bo$9bo4bo$9bo$9b
o!
As usual, the active pattern shown is a contrived example — this beehive to pre-TL transformation is reasonably common in my experience, but it occurs in several different ways, so it's difficult to find a "typical" example with a extremely simple active region... An unwelded variant with eaters is smaller where it fits, but the clearance is much worse.

EDIT: Here's another example, just to show that many different types of interactions will work:

Code: Select all

x = 21, y = 24, rule = B3/S23

o$11bo$9b2o!
Also, a legitimate, if useless, Herschel catalysis:

Code: Select all

x = 21, y = 32, rule = B3/S23
8b2ob2o$9bobo$4b2obo5bob2o$3bobob2o3b2obobo$2bo6bobo6bo$3b6o3b6o$3o15b

15bo$13b3o!
And a useless self-destructing H-to-H:

Code: Select all

x = 45, y = 24, rule = B3/S23
37b2o$36bobo$36bobobo$33b2obo2bobo$32bo2bobobo2bo$31bobo3bobob2o$32bo

2o$14bo6b3o$11b3o$11bo!
To my amazement, after some more experimentation, this catalyst seems to be remarkably promising, because it is shockingly good at catalyzing things that look even vaguely like B heptominoes. Exhibit A:

Code: Select all

x = 113, y = 25, rule = B3/S23

CatForce seems to agree that the beehive chain could be useful:

I only used a 2-catalyst search with the beehive chain, a block, and an eater on a raw Herschel (with FNG suppressor) to get five results, so...I expect that it will earn its bulk somewhere.
