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.
Assumptions: ➢ The number of assignees and the number of tasks are the same. ➢ Each assignee is to be assigned to exactly one task. ➢ Each task is to be presented by exactly one assignee.
For example, suppose an accounts officer has 4 subordinates and 4 tasks. The subordinates differ in efficiency and take different time to perform each task. If one task is to be assigned to one person in such a way that the total person hours are minimised, the problem is called an assignment problem.
The Hungarian matching algorithm, also called the Kuhn-Munkres algorithm, is a O ( ∣ V ∣ 3 ) O\big(|V|^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.
There are mainly four methods to solve assignment problems: Hungarian method. Enumeration Method. Simplex method. Transportation method.

John Pates Balancing the matrix. With the Hungarian Method, the first step would be to balance the matrix. Reduce Rows. Find the minimum value in each row and subtract the row by that minimum value. Reduce Columns. Cover 0s with Fewest Lines. Adjust the Matrix. Find unique 0s.
In applied mathematics, the maximum generalized assignment problem is a problem in combinatorial optimization. This problem is a generalization of the assignment problem in which both tasks and agents have a size. Moreover, the size of each task might vary from one agent to the other.
