In general, there is a tension in linear programming between the ease of obtaining fractional solutions and the desirability of integer ones. as we shall see in chapter 8, finding the optimum integer solution of an lp is an important but very hard problem, called integer linear programming.
2 2 Examples Of Integer Linear Programming Problems 1 7 Pages 1 9 Linear programming aims in this chapter we explain what is meant by a linear programming problem. Mixed integer linear programs (mixed integer linear program, milp, mip) may require only some of them to be integer. in this section: integer variables add much modeling power. Sometimes the solution of a programming problem can be partly real and partly integer. if our system is not prepared for such problems, we can employ the following approximation. In this case, we will be able to solve ilps in polynomial time. in this case, we can show a non polynomial lower bound on the complexity of solving ilps. they perform well on some important instances. but, they all have exponential worst case complexity. the largest ilps that we can solve are a 1000 fold smaller.

In 1984, karmarkar discovered yet another new algorithm for linear programming, the interior point method. it proved to be a strong competitor for the simplex method. Solve the problem as an ordinary lp problem neglecting the integer requirements. if the optimum values of the variables are not integers, then choose the basic variable which has the largest fractional value, and generate gomory constraint for that variable. In this chapter we study the or (simplex algorithm). it was the first algorithm to solve linear programming problems proposed in 1947 by george dantzig in a technical report “maximization of a linear function of variables subject to linear inequalities” [dan51].
