README
基于选择均匀分布的数据源选择下一个元素使用的选择管理器。
无限迭代
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, ...
迭代限制和导出
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], ] */
单次决策
use Smoren\ProbabilitySelector\ProbabilitySelector; $ps = new ProbabilitySelector([ // data // weight ['first', 1], ['second', 2], ]); $ps->decide(); // second $ps->decide(); // second $ps->decide(); // first
