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

@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.

@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

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

4:08 AM

Can you actually use that function?

Probably

via ∆Ė?

Yes

but then what would x be?

lyxal

There's also other commands for substituting values of x

Nitrodon

4:12 AM

!!/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

are yall using Adám's lb?

I am

Nitrodon

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

@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.

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

lyxal

4:34 AM

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):

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

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

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

Nitrodon

4:41 AM

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

lyxal

Nitrodon

by trying to read an empty stack?

5:25 AM

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 «

lyxal

@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

@Nitrodon something like Z⁽ƒiM would work

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

how bout cell evolution as puzzle?

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

7:50 AM

"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

so the rules are

The cell evolution follows these rules:
1. '0' indicates no live cell
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)
