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 a linear programming problem?
- An objective function is a linear function in two or more variables that is to be optimized (maximized or minimized). Linear programming problems are applications of linear inequalities, which were covered in Section 1.4. A linear programming problem consists of an objective function to be optimized subject to a system of constraints.
What are the properties of linear programming?
- A basic property of any linear programming problem with a bounded feasible region is that every feasible solution can be ex- pressed as a convex combination of the CPF solutions (perhaps in more than one way). Similarly, for the augmented form of the prob- lem, every feasible solution can be expressed as a convex combi- nation of the BF solutions.
What is the simplex method for solving linear programming problems?
- 2 1544 SOLVING LINEAR PROGRAMMING PROBLEMS: THE SIMPLEX METHOD 1The increase in b imust be sufficiently small that the current set of basic variables remains optimal since this rate (marginal value) changes if the set of basic variables changes.
