Here's a challenge that shouldn't be too hard:

VyMC: Given an algebraic expression including only +-*/^x for addition, subtraction, multiplication, division, exponentiation and variable x, return a list of the anti-derivative and firstderivative

Nitrodon

so @f:2|;@f; is a really verbose $?

lyxal

@Nitrodon essentially, yes.

@Nitrodon Just so you know, if there's weird stuff going on, we'll probably blame it on the rewrite, no matter how long it's been an issue

@mathcat My guess? The word fuck in brainfuck

@lyxal hint: use ∆ė and ∆i- they may or may not do differentiation and integration

PyGamer0

lmao

Nitrodon

or they might be the nth digit of e and/or pi.

lyxal

04:06

@Nitrodon the string overloads exist, they just haven't made it into the documentation even though I'm pretty sure I placed them there once

Nitrodon

Vyxal Bot

@Nitrodon ⟨ x**3/3 + 4*x | `2*x` ⟩

lyxal

Excellent

Nitrodon

Should I break things by inputting x^x?

lyxal

I don't know if it does break anything

All the algebra stuff is handled by Sympy

Nitrodon

04:08

Can you actually use that function?

lyxal

Probably

Nitrodon

via ∆Ė?

lyxal

Yes

Nitrodon

but then what would x be?

lyxal

There's also other commands for substituting values of x

Nitrodon

04:12

!!/run `x^x`∆i

Vyxal Bot

@Nitrodon Integral(x**x, x)

Nitrodon

I don't think it has a closed form.

lyxal

As I said, it uses Sympy to do all algebraic stuff, so that's Sympy's best representation

Nitrodon

I don't know that much Python, and I've never used Sympy.

lyxal

Ah, well Sympy is a symbolic math library

It's well known and widely used within the python community

PyGamer0

04:15

are yall using Adám's lb?

lyxal

I am

Nitrodon

I'm using it right now. Apparently some things changed and haven't been updated in the tooltips though.

Niko

lyxal

@Nitrodon if in doubt, use the keyboard at vyxal.pythonanywhere.com

VyMC: Given a list of strings and positive integers, return only items which are palindromic.

that should be much simpler

Nitrodon

Vyxal Bot

04:22

@Nitrodon ⟨ 232 | `radar` ⟩

lyxal

good job

VyMC: Given a non-empty string, return the percentage of each character. E.g.

"this is a certified bruh moment" -> [["t", 3/31], ["h", 2/31], ["i", 4/31], ["s", 2/31], [" ", 5/31], ["a", 1/31], ["c", 1/31], ["e", 3/31], ["r", 2/31], ["f", 1/31], ["d", 1/31], ["b", 1/31], ["u", 1/31], ["m", 2/31], ["o", 1/31], ["n", 1/31]]

I clearly don't know what I'm doing.

lyxal

04:34

Hint: Ċ will help

also, the documentation for Ṡ and the multi-element lambdas has been fixed

Nitrodon

but if I divide that by the length directly, I would probably get [[["t"], 3/31], ...]

lyxal

@Nitrodon which is also where ƛ...; might come in handy

it maps a function to each item in the top of the stack

so for example (and I don't expect you to know exactly what's happening here):

Nitrodon

(Is my guess as to what would happen correct?)

lyxal

04:38

@Nitrodon pretty much

@VyxalBot obviously it's FizzBuzz, but the point is that it maps ₍₃₅kF½*∑∴ to each item in the range 1...40

Nitrodon

yeah, I can see what Ċ does from the documentation.

lyxal

that's what Ċ does

now what if you were to map something over that list returned by Ċ that only touched the tail of each list

it's worth mentioning that ÷ dumps the contents of a list onto the stack

!!/run 1 20r÷W

lyxal

obviously that doesn't look like it did anything, but the W is to show what the stack would be

Nitrodon

04:41

I'm just wondering now how to get the 31 from inside the lambda.

lyxal

Have we mentioned how to explicitly take input?

Nitrodon

by trying to read an empty stack?

lyxal

no

Nitrodon

That's the only way I know.

lyxal

!!/run ? ? + - 3 4

Vyxal Bot

here's a harder puzzle:

oh right, the first input would be top of stack

One last thing I forgot to teach is string compression

There's two kinds: dictionary compression and base255 compression

Base255 compression is probably the easiest to explain

Oh nice lyxal teachiing vyxal

the next adam lol

lyxal

05:25

Given a string of lower case letters and spaces, it converts it from a custom base 27 to base 10

It then turns that base 10 number into a custom Base255 number

This kind of string is delimited with «

The base255 compressed version of a string can be obtained by using øc

just a tiny little distraction and question and request and announcement can you all or please dont or will you all cast a lot of downvotes if i write an answer to the recent downvoted tip question at some point

lyxal

05:35

@Nitrodon because mapping is monadic - it only takes a single argument

In this case, it's taking the list of indices, and indexing each indice into itself

emanresu A

Wow, y'all're still going

lyxal

@Nitrodon something like Z⁽ƒiM would work

lyxal

@Nitrodon not yet at least. That's something we're getting @hyper-neutrino to work on

What's happened is that it's indexed into a special "short dictionary"

Non-ascii characters on their own get words from a shorter dictionary that can only contain 161 words at the most

A: Tips for Golfing in Vyxal

Utilise the Short Dictionary Note: This is a 2.6.x+ feature only Newer versions of Vyxal have a neat little feature where 1 character SCCs are indexed into a special "short" dictionary of overlyspecialised "words".

there is only handwriting

DialFrost

how bout cell evolution as puzzle?

Niko

Lets just say... our class didn't introduce textbook, but a large part of exam is textbook

DialFrost

"Your lab needed to simulate how a particular cell evolves over time in a 2D grid space"

something like that

issit a gd idea?

so like given an integer n (grid size) which is a square

then print out the evolution

ATaco

07:50

"Evolution"?

DialFrost

like this

0 0 0 0 0
0 0 0 0 0
0 0 1 0 0
0 0 0 0 0
0 0 0 0 0

the 0 represents dead

1 alive

the 1 will spread around itself

and then it will die

ATaco

So a basic Cellular Automata with the rule, "Alive cells die, new cells are born if they have any neighbors"

DialFrost

yes

they *will haev neighours 100% of the time kinda

ATaco

Simple enough, not sure if there's already a challenge for it.

DialFrost

not that simple

another rule is

that the number can be >=1

so
0 0 0
0 1 0
0 0 0

ATaco

07:52

No more complex than Implementing the Game of Life

becomes

2. A positive number indicates a live cell. The number indicates its age.
3. A cell will grow from age 1 to 5 in each evolution
4. After age 5, a cell will die at the next evolution (resetting to '0')
5. If a cell has 4 or more neighbours (adjacent and diagonally), it will die due to over-crowding.
6. In each evolution, a live cell will spread to its neighbour (adjacent and diagonally) if there is no live cell there and that neighbour is not overcrowded (surrounded by less than 4 cells)

Remember, Complexity does not necessarily make for a good challenge. The best challenges are small in scope, but very interesting non-the-less.
