The assignment problem is a fundamental combinatorial optimization problem. In its most general form, the problem is as follows: The problem instance has a number of agents and a number of tasks. Any agent can be assigned to perform any task, incurring some cost that may vary depending on the agent-task assignment.
What is Task Assignment Approach in Distributed System?
In the working of the Task Assignment Approach, the following are the assumptions: The division of an individual process into tasks. Each task's computing requirements and the performance in terms of the speed of each processor are known. The cost incurred in the processing of each task performed on every node of the system is known.

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.
