Linear sum assignment problem是指将有若干个任务需要被分配给某些人员去完成,每个人员只能完成一个任务,且每个任务只能由一个人员完成。同时,每个任务和每个人员都会有一个分值或成本,分配方案的目标是使得总成本最小。 这个问题可以用图论中的二分图来表示,将人员和任务分别放在两个部分中,并在它们之间建立边,表示...
Linear Assignment Problems are fundamental combinatorial optimization problems that appear throughout domains such as logistics, robotics and telecommunications. In general, solving assignment problems to optimality is computationally infeasible even for contexts of small dimensionality, and so heuristic ...
Linear sum assignment算法,也称为匈牙利算法或者Kuhn–Munkres算法,是一种解决线性和分配问题(Linear Sum Assignment Problem)的优化算法。线性和分配问题是指给定一个n x n的代价矩阵,任务是将其中的n个任务分配给n个执行者,并使得总的分配代价最小化。这个问题在实际生活中有很多应用,比如任务分配、人员调度以及机...
note that the problem is not actuallysolved using a general-purpose ILP(integer linear programming) solver, it is just a convenient framework in which to express the problem Perfect/Complete matching = every vertex has a match The constraint that the sum of each row and column is equal to on...
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。 返回:: row_ind, col_ind:数组 一组行索引和一个对应的列索引,给出最佳分配。分配的成本可以计算为cost_matrix[row_ind, col_ind].su...
linear_sum_assignment算法是一种用于解决指派问题(Assignment Problem)的有效方法。指派问题是一种常见的最优化问题,在许多实际应用中都有着重要的作用。该算法在scipy库中被广泛应用于解决各种指派问题,例如任务分配、资源分配、匹配问题等。 具体来说,linear_sum_assignment算法可以应用于以下几个方面: 1.任务分配:在...
