README
PHP中的匈牙利算法实现。匈牙利算法可以用于在给定的成本矩阵下,在两种类型的实体之间找到最优(最小成本)的分配。匈牙利算法也称为Kuhn–Munkres算法或Munkres分配算法。
使用Composer安装
在bash/zsh中执行以下命令
composer require arthurkushman/hungarian
示例用法
为匈牙利类定义一个包含分数作为输入的方阵。方阵必须是一个由n个数组(行)组成的数组,每个数组包含n个分数。行数组中每个元素的键必须等于列的键。
<?php use Hungarian\Hungarian; // Define the score matrix as n arrays consisting of n numerical values $matrix = [ [1, 2, 3, 0, 1], [0, 3, 12, 1, 1], [3, 0, 1, 13, 1], [3, 1, 1, 12, 0], [3, 1, 1, 12, 0], ]; // Create a new Hungarian problem using the score matrix as input $hungarian = new Hungarian($matrix); // Solve the problem using the Hungarian algorithm and get the solution as an array with the row and column as key and value, respectively $allocation = $hungarian->solveMin();
