What is an optimal solution to a linear programming problem?
- Given that an optimal solution to a linear programming problem exists, it must occur at a vertex of the feasible set. If the optimal solution occurs at two adjacent vertices of the feasible set, then the linear programming problem has infinitely many solutions. Any point on the line segment joining the two vertices is also a solution.
What is the difference between optimal solution and optimal value?
- The optimal solution is the point that maximizes or minimizes the objective function, and the optimal value is the maximum or minimum value of the function. The context of a problem determines whether we want to know the objective function’s maximum or the minimum value.
How to find feasible solutions to a LP problem?
- Finding feasible solutions to a LP In all the examples we have seen until now, there was an “easy” initial basic feasible solution: put the slack variables on the left hand side. How- ever, this is not always the case, especially for minimization problems, or problems with equality constraints in the original model.
How do you find the optimal solutions at which the maximum and minimum occur?
- To find the optimal solutions at which the maximum and minimum occur, we substitute each corner point into the objective function, P = 10 x ?3y. We now look at our chart for the highest function value (the maximum) and the lowest function value (the minimum). The maximum value is 32 and it occurs at the point (5, 6).
