README
Selection manager for choosing next elements to use from data source based on uniform distribution of selections.
Infinite iteration
use Smoren\ProbabilitySelector\ProbabilitySelector; $ps = new ProbabilitySelector([ // data // weight // initial usage counter ['first', 1, 0], ['second', 2, 0], ['third', 3, 4], ]); foreach ($ps as $datum) { echo "{$datum}, "; } // second, second, first, second, third, third, second, first, third, second, third, third, second, first, third, ...
Iteration limit and export
use Smoren\ProbabilitySelector\ProbabilitySelector; $ps = new ProbabilitySelector([ // data // weight ['first', 1], ['second', 2], ]); foreach ($ps->getIterator(6) as $datum) { echo "{$datum}, "; } // second, second, first, second, second, first print_r($ps->export()); /* [ ['first', 1, 2], ['second', 2, 4], ] */
Single decision
use Smoren\ProbabilitySelector\ProbabilitySelector; $ps = new ProbabilitySelector([ // data // weight ['first', 1], ['second', 2], ]); $ps->decide(); // second $ps->decide(); // second $ps->decide(); // first
