Formulation of linear programming
WebThe most fundamental optimization problem treated in this book is the linear programming (LP) problem. In the LP problem, decision variables are chosen so that a linear function of the decision variables is optimized and a simultaneous set of linear constraints involving the decision variables is satisfied. 2.1 The Basic LP Problem WebMar 28, 2024 · Step 1: Create mathematical formulation from the given problem. If not given. Step 2: Now plot the graph using the given constraints and find the feasible region. Step 3: Find the coordinates of the feasible region (vertices) that we get from step 2. Step 4: Now evaluate the objective function at each corner point of the feasible region.
