called a feasible solution to the linear programming problem. A feasible solution that minimizes the objective function is called an optimal solution.
The objective function also specifies a direction of optimization either to maximize or minimize. An optimal solution for the model is the best solution as
Definition: A linear programming problem (LP) is an optimization prob- Definition: An optimal solution to a linear program is the feasible solution.
17 mar. 2015 Linear Programming deals with the problem of optimizing a linear ... A feasible solution is optimal if its objective function value is equal.
A LPP in standard form has m constraints and n variables. The number of basic feasible solutions will be. (a) C:J (b) :::; (~). (c) 2 (~). (d) none of these
variables are non-negative is called a basic feasible solution. 10) When does an LPP posses a pseudo-optimal solution? Solution:.
Most of these optimization problems do not admit an optimal solution that can be computed in a reasonable time that is in polynomial time (See Chapter 3).
We then apply the Robust Optimization method- ology (Ben-Tal and Nemirovski [1-3]; El Ghaoui et al. [56]) to produce “robust” solutions of the above LPs which
Obviously besides the optimal solutions of linear programming problems in which we take each objective function
We give a definition of the normul form of an optimal solution of a linear programming problem and propose an algorithm to reduce the optimal solution to
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
that we should focus our attention on in order to identify the optimal solution of the LP De nition (Basic Solution) Given an LP with n decision variables and m constraints a basic solution of the corresponding initial system is a solution of the initial systems (not taking into account nonnegative constraints) in which n of the variables x 1

The normal form of an optimal solution allows one to describe the entire set of optimal solutions and derive the formula for the dimension of this set in terms of the parameters of the normal form In Section 4 the optimal solution sets of the primal and dual LPPs are treated simultaneously
optimal solution Notice that the value of a is 0 which means that the original LP is feasible The value of x is 5 and the objective function is ?5 Negating that we get that the optimal objective function value is 5 as we expected
remain optimal With the particular choice of ? = ?20 we have 100 20 10+? = 100 20 ?10 It follows that the new solution (0 20 0 0 ?10) is infeasible As in part (a) we will not attempt to derive a new optimal solution The shadow price of the second resource can be read directly from the top entry in the third column of P
