What is the first step in formulating a linear programming problem?
The first step in formulating a linear programming problem is to determine which quan- tities you need to know to solve the problem. These are called the decision variables. The second step is to decide what the constraints are in the problem.
Which of the following is a characteristic of a linear programming problem?
Characteristics of Linear Programming Linearity- The relationship between two or more variables in the function should be linear. Finiteness- There always should be finite and infinite input and output numbers. If the function has infinite factors, the optimal solution will not be feasible.
