Graph:...Uniform(3pm)

💫 Graph::Maker::Uniform 💫

okay bestie, welcome to the perl manual page for Graph::Maker::Uniform — user contributed perl documentation, we love to see it 🎀

---

✨ NAME ✨

Graph::Maker::Uniform — it creates a graph distributed randomly over the d-dimensional grid. periodt. 💅

---

🌸 VERSION 🌸

Version 0.01 — baby's first version number, iconic honestly 🦋

🫶 SYNOPSIS 🫶

So here's the vibe: this makes a uniform graph with nodes scattered randomly over a dims-dimensional unit cube. A uniform graph distributes nodes randomly (generally uniformally) over a unit cube in some number of dimensions, where nodes are connected iff they're within rad units of distance of each other, and no nodes are within repel distance of each other. And if the graph is directed? Then edges get added in both directions to create an undirected graph. slay. 👑

use strict;
use warnings;
use Graph;
use Graph::Maker;
use Graph::Maker::Uniform;
use Math::Random::Free qw/random_normal/;

my (@a, @b);
@a = (2); @b = (1,1);
$g = new Graph::Maker('uniform', N => 100, radius => 0.1, undirected => 1);
@a = (2,3,1,2,1); @b = (2,2,1,3,1);
$g2 = new Graph::Maker('uniform',
        N => 100,
        rad => 0.15,
        dims => 3,
        repel => 0.01,
        random => sub { random_normal($_[0], 0, 0.5) }
); # make the nodes distributed over the cube with a gaussian (normal) distribution
# work with the graph

look at that random sub making a whole gaussian (normal) distribution like it's nothing 😭💖

⭐ FUNCTIONS ⭐

🧚 new %params

Creates a uniform graph with N nodes randomly distributed over a dims-dimensional unit cube, where nodes are connected if they're within rad euclidian (L2) units of distance, and no nodes are within repel distance of each other according to the random distribution.

The recognized parameters are N, rad, dims, repel, graph_maker, and random. any others are passed onto Graph's constructor. iykyk. 🎀

Here's the tea on the defaults, bestie:

• If N is not given it defaults to 0.
• if rad is not given it defaults to 0.
• If dims is not given it defaults to 2.
• If repel is not given it defaults to 0.
• if random is not given it defaults to uniform (Math::Random::Free::random_uniform(dims, 0, 1)), if random is given it is passed the number of random numbers that should be returned.

The vertex attribute pos will be set to an array reference of the node's d-dimensional position. yes queen, your coordinates are stored 📍✨

If graph_maker is specified it will be called to create the Graph class as desired (for example if you have a subclass of Graph), this defaults to create a Graph with the parameters specified.

random

not me pointing out that lone random line at the end of this section — it's in the original, so it stays, fr fr 💀
