Clustering algorithms for PHP

Usage
-----

[](#usage)

```
use \webd\clustering\KMeans;
use \webd\clustering\GMeans;
use \webd\clustering\RnPoint;

// These examples use points in Rn, but some algorithms (like KMeans)
// support points in non-euclidean spaces
$points = array(
    new RnPoint(array(1, 1)),
    new RnPoint(array(2, 2)),
    new RnPoint(array(2, 3))
);

// Simple KMeans
$kmeans = new KMeans;
$kmeans->k = 2;
$kmeans->n = 10;
$kmeans->points = $points;
$kmeans->run();

var_dump($kmeans->centers);

// GMeans (no need to specify the number of clusters)
$nd = new \webd\stats\NormalDistribution();

// Create points around (1, 1) and (9, 9)
$points = array();
for ($i = 0; $i < 100; $i++) {
    $points[] = new RnPoint($nd->sample()+1, $nd->sample()+1);
    $points[] = new RnPoint($nd->sample()+9, $nd->sample()+9);
}

$gmeans = new GMeans();
$gmeans->points = $points;
$gmeans->run();
var_dump($gmeans->found_centers);
```

Top contributor holds 100% of commits — single point of failure

How is this calculated?**Maintenance (25%)** — Last commit recency, latest release date, and issue-to-star ratio. Uses a 2-year decay window.

**Popularity (30%)** — Total and monthly downloads, GitHub stars, and forks. Logarithmic scaling prevents top-heavy scores.

**Community (15%)** — Contributors, dependents, forks, watchers, and maintainers. Measures real ecosystem engagement.

**Maturity (30%)** — Project age, version count, PHP version support, and release stability.
