CMC: functions f and g such that f(g(c))(x) ≡ g(x) for all x, for exactly one value of c

Adám

Does this mean f takes two arguments?

pxeger

yeah, ok, you can see it that way

Adám

In APL, I'd write that as (x f g c) ≡ g x

PyGamer0

@pxeger do i make 2 functions satisfying those conditions?

pxeger

yes

PyGamer0

15:24

looks very hard..

for my tiny brain

pxeger

Yes, I think it's an interesting computational puzzle

thejonymyster

15:36

so f takes (something) as input and returns a function?

pxeger

or you could make f a function that takes two arguments

thejonymyster

right hm

Wheat Wizard

@WheatWizard [4,4,1,4,2,5,1] is better for n=7

thejonymyster

f(x,y) = xy
g(x) = x
c=1

pxeger

Nice

thejonymyster

15:39

im sure there are interesting nontrivial answers too :P

pxeger

Bonus puzzle: do it without (hover for spoiler)

oops

thejonymyster

i wonder what this spoiler says

can you not just (hover for spoiler)

pxeger

hmm actually I think (hover for spoiler)

@WheatWizard Is there an accepted name for "a directed graph where every node has at most two arcs out"?

thejonymyster

@pxeger nice generalization :D can it work in cases where that is not the case?

cases where that is not case....

"in different cases"?

Wheat Wizard

@pxeger Don't think so.

pxeger

15:53

@thejonymyster I think that's basically the total solution space

thejonymyster

darn

Wheat Wizard

@pxeger Note that not every directed graph where every node has at most two arcs out is a valid lilypond.

PyGamer0

@pxeger i hate hover for spoilers cause i cant see them on mobile

thejonymyster

we should start pastebinning spoilers

PyGamer0

@thejonymyster dzaima.github.io/…

Seggan

15:58

@pxeger wait how did you do that

pxeger

@PyGamer0 Sometimes I use https://t.pxeger.com/xs.html?v=Tony+Stark+dies+in+Endgame, but that's kinda a pain to type out

thejonymyster

@Seggan check the edit history and test in sandbox :P

pxeger

I'd like to be able to use data:text/plain,Tony+Stark+dies+in+Endgame, but SE doesn't recognise data: URIs

sorry to anyone who's not yet watched Endgame

Seggan

@thejonymyster ah

Wheat Wizard

I haven't but I don't think I ever will and I don't know who Tony Stark is.

pxeger

16:00

sandbox

I've not watched it either. I don't know why that was the first spoiler I thought of

PyGamer0

@pxeger what is endgame?

pxeger

Avengers movie from 2019

PyGamer0

oh fun fact: endgame was the first marvel movie i watched :P

@WheatWizard some guy with an iron suit and a watch at his heart of the suit?

thejonymyster

@PyGamer0 started at the end, now you have to watch all the way backwards to startgame

Seggan

@PyGamer0 same lol

user

16:15

Is Endgame the one where half the world dies or the one after that?

Seggan

16:30

the one after

infinity war is the one where half the universe dies

PyGamer0

and my second marvel movie was spiderman-no way home

which i watched with 2 of my classmates :p

it was boring

Razetime

seems like mama fun roll has posted after 3 years!

(and in BQN!)

pxeger

almost exactly 3 years, in fact

coincidence?

PyGamer0

yesterday, by Mama Fun Roll

https://codegolf.stackexchange.com/a/248677/41247 anyone well-versed in BQN have any ideas for golfing this down?

hyper-neutrino

2019 really does not feel like 3 years ago ngl

pxeger

16:39

well there were about 2 years of void between then and now

PyGamer0

@hyper-neutrino yeah..

pxeger

lmao autocorrect

covid -> void

PyGamer0

it feels like yesterday

@pxeger LMAO

amazing outdated autocorrect

Seggan

what browser yall recommend for my 7 year old laptop that has to run visual studio unity and blender all at the same time

i need one that has the least performance impact

Razetime

internet explorer 7

Seggan

16:48

@pxeger void covid(void)

hyper-neutrino

both work :P

ophact

Hello again...

it's almost the end of the school year so I might finally have time to golf again

mathcat

Hi guys

I'm in some camp and I have nothing to do but eat pizza except that I don't eat cheese.

thejonymyster

17:09

take all the cheese off

Adám

17:32

Doesn't Java need something like void covid?

DLosc

17:49

@pxeger Apology accepted :P

Seggan

@Adám yeah

literally every c language

user

18:34

@mathcat Put the pizza in the microwave until the cheese starts flowing. Then put that cheese into a cup and drink it. Voila, you have consumed the cheese by drinking it instead of eating it

@Adám Need for what?

mathcat

18:51

I think I'll eat my oreos instead

dang

2 hours later…

Q: Generate Fibonacci Primes Quickly

Unsurprisingly, fibonacci primes are primes that are also Fibonacci numbers. There are currently 34 known Fibonacci primes and an additional 15 probable Fibonacci primes. For the purpose of this challenge, the Fibonacci numbers are the sequence \$F_n\$ defined as \$F_1 = 1\$, \$F_2 = 1\$, and \$F...
