In this chapter we shall study some linear programming problems and their solutions by graphical method only
Second we consider basic approaches that have been developed for solving integer and mixed-integer programming problems. 9.1 SOME INTEGER-PROGRAMMING MODELS.
The above stated optimisation problem is an example of linear programming problem. Linear programming problems are of much interest because of their wide.

Integer Programming. Linear Integer Programming. Types of integer programming problems. Pure Integer Programming Problem: All variables are required to be
An IP in which only some of the variables are required to be integers is called a mixed integer programming problem. For example max z. 3x1. 2x2. s.t. x1 x2. 6.
Thus a greater-than-or-equal-to constraint in a minimization problem has an associated nonnegative dual variable. The primal and dual problems that we have
be able to find solutions to linear programming problems using graphical means;. • be able to apply the simplex method using slack variables;. • understand the
In. AMPL one can easily change a linear programming problem into an integer program. The downside of all this power
For example it is usually simple to give a nonlinear extension to any linear program. Moreover
Figure 9.8 An integer programming example. If the integrality restrictions on variables are dropped the resulting problem is a linear program. We will call it
decision variables that maximize or minimize the objective function and sat- isfy all constraints. The following example shows how an operational problem can be
A similar observation is made for example (3) except that the primal problem is now infeasible while the dual variable y1 may be increased indefinitely. In
