The problem may also be phrased as a minimization problem by considering, instead of edge weights, a set of non-negative edge costs, , where W is at least as large as the maximum of all the edge weights.

It can also be stated as: how to determine the best possible assignment of workers to jobs, such that the total ratings are maximized  . Related Works Franses and Gerhard  studied an assignment problem particular to the personnel scheduling of organisations such as laboratories.

Algorithm : Step - 1 : Subtract the minimum element in each row from every entry in that row of a cost table.

Step - 2 : Subtract the minimum element in each column from every entry in that column of the resulting equivalent cost table.

Here the authors have to assign tasks to employees.

The authors focused on the situation where this assignment problem reduces to constructing maximal matchings in a set of interrelated bipartite graphs.Toroslu and Arslanoglu  , presented variations of the standard assignment problem with matching constraints by introducing structures in the partitions of the bipartite graph, and by defining constraints on these structures.  presented a novel solution designed to bridge the gap between the need for high-quality matches and the need for timeliness.By applying constraint programming, a subfield of artificial intelligence, the authors dealt successfully with the complex constraints encountered in the field and reach near-optimal assignments that take into account all resources and positions in the pool.The assignment problem can be written mathematically as: Minimize 2.3.Hungarian Method The following algorithm applies the above theorem to a given n × n cost matrix to find an optimal assignment. Output : An equivalent cost table has all the zero elements required for a complete set of assignments which constitute an optimal solution.Strategy : To concert the cost table into equivalent cost tables until we get an optimal solution.Stack Exchange network consists of 175 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their knowledge, and build their careers.Visit Stack Exchange Operations Research Stack Exchange is a question and answer site for operations research and analytics professionals, educators, and students.

• ###### Hungarian Maximum Matching Algorithm Brilliant Math.

The Hungarian matching algorithm, also called the Kuhn-Munkres algorithm, is a O ∣ V ∣ 3 O\bigV^3\big O ∣ V ∣ 3 algorithm that can be used to find maximum-weight matchings in bipartite graphs, which is sometimes called the assignment problem.…

The assignment problem is a special case of the transportation problem, which in turn is a special case of the min-cost flow problem, so it can be solved using algorithms that solve the more general cases. Also, our problem is a special case of binary integer linear programming problem which is NP-hard. But, due to the specifics of the problem, there are more efficient algorithms to solve it.…

This problem is Kuhn’s Hungarian method Kuh55. This method is of major theoretical interest and is still used widely. It maintains a price for each object and an incomplete assignment of persons and objects. At each iteration, the method chooses an unassigned person and computes a shortest augmenting path from this person to the set of unassigned objects, using reduced costs as arc.…
