Hungarian Method
The Hungarian method is a computational optimization technique that addresses the assignment problem in polynomial time and foreshadows following primal-dual alternatives. In 1955, Harold Kuhn used the term "Hungarian method" to honour two Hungarian mathematicians, Dénes Kőnig and Jenő Egerváry. Let's go through the steps of the Hungarian method with the help of a solved example.
Hungarian Algorithm for Assignment Problem
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 ...

Hungarian Algorithm for Assignment Problem
Different approaches to solve this problem are discussed in this article. Approach: The idea is to use the Hungarian Algorithm to solve this problem. The algorithm is as follows: For each row of the matrix, find the smallest element and subtract it from every element in its row. Repeat the step 1 for all columns.
Hungarian algorithm
The Hungarian method is a combinatorial optimization algorithm that solves the assignment problem in polynomial time and which anticipated later primal-dual methods.It was developed and published in 1955 by Harold Kuhn, who gave it the name "Hungarian method" because the algorithm was largely based on the earlier works of two Hungarian mathematicians, Dénes Kőnig and Jenő Egerváry.
An Assignment Problem solved using the Hungarian Algorithm
The matrix below shows the cost of assigning a certain worker to a certain job. The objective is to minimize the total cost of the assignment. Below we will explain the Hungarian algorithm using this example. Note that a general description of the algorithm can be found here. Step 1: Subtract row minima.

Assignment problem: Hungarian method 3
The Hungarian method is a combinatorial optimization algorithm which was developed and published by Harold Kuhn in 1955. This method was originally invented for the best assignment of a set of persons to a set of jobs. It is a special case of the transportation problem. The algorithm finds an optimal assignment for a given "n x n" cost matrix.
The Hungarian Algorithm for the Assignment Problem
The Hungarian method is a combinatorial optimization algorithm which solves the assignment problem in polynomial time . Later it was discovered that it was a primal-dual Simplex method.. It was developed and published by Harold Kuhn in 1955, who gave the name "Hungarian method" because the algorithm was largely based on the earlier works of two Hungarian mathematicians: Denes Konig and Jeno ...

The Hungarian Method: The following algorithm applies the above theorem to a given n × n cost matrix to find an optimal assignment. Step 1. Subtract the smallest entry in each row from all the entries of its row. Step 2. Subtract the smallest entry in each column from all the entries of its column. Step 3.
Assignment Problem and Hungarian Algorithm
This problem is known as 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 ...

1. INTRODUCTION The Hungarian Method [ 11 is an algorithm for solving assignment problems that is based on the work of D. Konig and J. Egervgry. In one possible interpretation, an assignment problem asks for the best assignment of a set of persons to a set of jobs, where the feasible assignments are ranked by the total scores or ratings of the ...

Example 1: Hungarian Method. The Funny Toys Company has four men available for work on four separate jobs. Only one man can work on any one job. The cost of assigning each man to each job is given in the following table. The objective is to assign men to jobs in such a way that the total cost of assignment is minimum. Job.

The Hungarian Method can also solve such assignment problems, as it is easy to obtain an equivalent minimization problem by converting every number in the matrix to an opportunity loss. The conversion is accomplished by subtracting all the elements of the given matrix from the highest element. It turns out that minimizing opportunity loss ...

Identify the minimum element in each column and subtract it from every element of that column. 3. Make the assignments for the reduced matrix obtained from steps 1 and 2 in the following way: For each row or column with a ...
Difference between solving Assignment Problem using the Hungarian
When using the Hungarian method, you do not build a model, you just pass the cost matrix to a tailored algorithm. You will then use an algorithm developed for that specific problem to solve it. Hence, it will most likely solve it faster since it is a specialist. So if you want to solve an AP you should probably use the tailored algorithm.
