apgsearch - haul requests

[Rhombic]

B2e3-akr5ij78/S23aij4at7e, which contains a small p184 RRO and numerous elementary spaceships (found by 83bismuth38), would be an interesting rule to apgsearch.

I'll take note of this one (I'm keeping a notepad queue for apgsearching). This Life-derived rule has some odd things going on:

Code: Select all

x = 37, y = 7, rule = B3-ck4kz5j/S23-cekq4t5r6a8
9b2o$9b2o11b2o10bo$21bob2o9b2o$3o21b2o7b4o$2bo21b3o6bobo$bo30b4o$34bo!

This is my current apgqueue list. Explore any of these because they show interesting properties for wildly different reasons. Currently searching.

I would like someone to help apgsearch Snowflakes (B2ci3ai4ci8/S02ae3eijkq4iz5a6i7e) so this elusive p2 can show up in C1 finally.

EDIT: Never mind I just didn't look hard enough

Wait, are you saying it is there? I don't see it anywhere in the C1 xp2 list.

EDIT: Also, I suggest B2in34-a/S1e2ekn34ent for apgsearching.

B2e3ai4aiw5i8/S1c2-a3-a5a6c please.
Oh and B2e3ai4aiw5i7e8/S1c2-a3-ar5a6c

[Majestas32]

B2e3ai4t5e6ciks1c2-a3-a4-aeit5ikr in C1 or D2x

[Apple Bottom]

B2e3ai4aiw5i8/S1c2-a3-a5a6c please.

That one's too prone to explosion to reasonably search; despite several attempts I've not been able to finish even 10,000 soups without it blowing up on me.

EDIT: nevermind, two hauls apparently went through right as I typed this. Still a pretty explosive rule, however.

[Majestas32]

b2-a3cs12-i has a bunch of weird oscillator periods.

Either C1, D4_+2, D4_x1, and/or D2_x

One thing I wonder is, why does apgsearch freeze when it hits an explosive soup, and never output anything? Doesn't zz_EXPLOSIVE exist to handle those kinds of situations?

I imagine it would eventually detect a zz_* pattern -- but this simply takes unfeasibly long.

Hmm, maybe a function could be implemented so that, if a soup takes more than a certain amount of time to process or goes above a certain size without stabilising, that soup is flagged as abnormal and the searching process continues. That would make it easier to search rules that explode, but quite rarely; currently, in certain rules I go through several thousand soups only to have the whole searching process suddenly freeze, preventing me from submitting a haul.

That sounds quite doable -- simply label the whole thing PATHOLOGICAL, and continue with the next soup.

What would a good cut-off value be? 5 minutes? 10? 30? You'd want to strike a balance between not accidentally labelling difficult-to-classify patterns (such as high-period yl's) as PATHOLOGICAL on one hand, and ensuring searchability on the other hand. (Mind, we're talking about rules here where there's an occasional problematic soup; if all (or most, or many) soups blow up, you still won't be able to search the rule, but that's more due to the rule's own dynamics than to apgsearch's optimism re: eventual stabilization.)

Something else that would be nice to have -- occasional status messages on the console if a problematic soup is encountered.

I don't know if Calcyman's going to read any of this (much less in this thread), or (if he does) whether he's going to have the time and inclination to implement anything, but if you cook up something yourself, let me know.

How about B2ce3ir/S12? My computer was doing 1 soup per second and got stuck after I generated a census to see what was wrong.

[wwei23]

B3/S2/C1 doesn't seem bad. In fact, my computer was able to do 100000000 soups in only about 20 hours, while 26 hours were needed to do 10000000 soups in B3/S23/1x256X2+1. What's going on is that we're trying to get a small lake to appear naturally, or some other still life with more than 8 cells.

[Majestas32]

@everyone wwei23 has come back

[77topaz]

@everyone wwei23 has come back

He was already back on the LifeWiki for about a month.

[KittyTac]

Welcome back, I guess, even though I wasn't around here when you left.

[Majestas32]

Same tho

C2_2 and C2_4 would also be good. They are the only C symmetries without P3s except for C1.

[Majestas32]

B2-a4ks12-i3ij has a p296 evolving from 3 cells as well as a c/30d spaceship.

[Majestas32]

b2e3-ajs23 has a p66 osc and loads of high period linear growths.

[Majestas32]

b2-a5k6n7cs12-i3ij4k5j has a ton o spaceships

[wwei23]

b2-a5k6n7cs12-i3ij4k5j has a ton o spaceships

Already on it.

[FlameandFury]

Please search B2-ac3aei4ae6i8/S23-ejq8.
It's a cool rule with lots of oscillators.

[Saka]

b2-ak3aej4ai5ai78s2-cn3aeir4air5ai6ac78 has widen-able linear growths.
b2-ak3aej4aeirw7e8s2-n3aer4eirtz5i7e8 has ships that have replicators attached.
