# Assignment problem

Assignment problem is a special type of linear programming problem which deals with the allocation of the various resources to the various activities on one to one basis. It does it in such a way that the cost or time involved in the process is minimum and profit or sale is maximum. Though there problems can be solved by simplex method or by transportation method but assignment model gives a simpler approach for these problems. In a factory, a supervisor may have six workers available and six jobs to fire. He will have to take decision regarding which job should be given to which worker.

Let there be n agents and n tasks. Any agent can be assigned to perform any task, incurring some cost that may vary depending on the agent-task assignment. It is required to perform all tasks by assigning exactly one agent to each task and exactly one task to each agent in such a way that the total cost of the assignment is minimized. Example: You work as a manager for a chip manufacturer, and you currently have 3 people on the road meeting clients.

### The Assignment Problem & Calculating the Minimum Matrix Sum (Python)

One of the most well-known combinatorial optimization problems is the assignment problem. Here's an example: suppose a group of workers needs to perform a set of tasks, and for each worker and task, there is a cost for assigning the worker to the task. The problem is to assign each worker to at most one task, with no two workers performing the same task, while minimizing the total cost. You can visualize this problem by the graph below, in which there are four workers and four tasks.

Im glad this company is not like those other scam companies using the students study difficulties as a source of income without providing relevant quality of work.
