What is the enumeration approach to solving assignment problems? Is it a practical way to solve a 5 row X 5 column problem? a 7 X 7 problem? Why? Discuss.

In this question, the enumeration method of solving assignment problems is discussed.
When using the enumeration method to solve an assignment problem, a linear programming model is used. This defined using:
The assignment model is that model in which we have to identify an optimal or best assignment means we have to assign the one to one works to the people so that we can find the optimal solution. The main objective is this that we have to minimize the total cost of the assignment and the maximization objective is also possible in this.
For representing an assignment model we can draw a table.
A from table we denote the rows to the people or jobs which we want to assign them. And the column shows the tasks or...
