WebThe steps to solve linear programming problems are given below: Step 1: Identify the decision variables. Step 2: Formulate the objective function. Check whether the function needs to be minimized or maximized. Step 3: Write down the constraints. Step 4: Ensure that the decision variables are greater than or equal to 0. (Non-negative restraint)
WebA linear program is in canonical form if it is of the form: Max z = cTx subject to: Ax ≤b x ≥0. A linear program in canonical form can be replaced by a linear program in standard form by just replacing Ax ≤b by Ax + Is = b, s ≥0 where s is a vector of slack variables and I is the m×m identity matrix. Similarly, a linear program in ...
