线性分配问题(LAP,Linear Assignment Problem)是一个经典的优化问题,其目标是在若干任务和若干工人之间进行分配,以最小化总成本。成本可以是时间、金钱等。 LAPJV算法(Linear Assignment Problem Jonker-Volgenant algorithm)是解决线性分配问题的一种具体方法。这是一种基于Jonker和Volgen

It is a native Python 3 module and does not work with Python 2.x, stick to pyLAPJV otherwise.Linear assignment problem is the bijection between two sets with equal cardinality which optimizes the sum of the individual mapping costs taken from the fixed cost matrix. It naturally arises e.g...
本文简要介绍 python 语言中scipy.optimize.linear_sum_assignment的用法。 用法: scipy.optimize.linear_sum_assignment()# 解决线性和分配问题。 参数:: cost_matrix:数组 二分图的成本矩阵。 maximize:布尔(默认值:假) 如果为真,则计算最大权重匹配。

Generally, there is a tendency to embed mathematical programming languages into imperative high-level programming language such as Python [76], [77], Java, C/C++ and Matlab, among others.12 In particular Diamond, Chu and Boyd's CVXPY [77] enables an object-oriented approach to constructing ...
