The linear sum assignment problem is also known as minimum weight matching in bipartite graphs. A problem instance is described by a matrix C, where each C[i,j] ...

The Hungarian maximum matching algorithm, also called the Kuhn-Munkres algorithm, is a O (V 3) algorithm that can be used to find maximum-weight matchings in bipartite graphs, which is sometimes called the assignment problem. A bipartite graph can easily be represented by an adjacency matrix, where the weights of edges are the entries.

14.01.2016 · The Hungarian algorithm, aka Munkres assignment algorithm, utilizes the following theorem for polynomial runtime complexity (worst case O(n 3)) and guaranteed optimality: If a number is added to or subtracted from all of the entries of any one row or column of a cost matrix, then an optimal assignment for the resulting cost matrix is also an optimal assignment for the …

27.04.2017 · So this seems very strange to me. I was solving the assignment problem on a 174x174 matrix first using Hungarian algorithm (munkres python package) and then solving it using the Google OR tools min-cost flow solver.I benchmarked the times it took and Munkres ran extremely slow (almost 12 times slower!):

19.09.2016 · This function can also solve a generalization of the classic assignment problem where the cost matrix is rectangular. If it has more rows than columns, then not every row needs to be assigned to a column, and vice versa. The method used is the Hungarian algorithm, also known as the Munkres or Kuhn-Munkres algorithm. Notes New in version 0.17.0.
