Assignment problem
Worked example of assigning tasks to an unequal number of workers using the Hungarian method. 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 ...
Solving Assignment Problem using Linear Programming in Python
In this step, we will solve the LP problem by calling solve () method. We can print the final value by using the following for loop. From the above results, we can infer that Worker-1 will be assigned to Job-1, Worker-2 will be assigned to job-3, Worker-3 will be assigned to Job-2, and Worker-4 will assign with job-4.

PDF Lecture 5 1 Linear Programming
The linear function that we want to optimize (x 1 + x 2 in the above example) is called the objective function. A feasible solution is an assignment of values to the variables that satis es the inequalities. The value that the objective function gives to an assignment is called the cost of the assignment. For example, x 1:= 1 3 and x 2:= 1 3
