Integer Programming<br />

possible IP instances. However, since some of them are hard, the general problem must be hard.<br />

● <strong>The</strong> transformation captures the essence of why IP is hard. It has nothing to do with having big<br />

coefficients or big ranges on variables; since restricting them to 0/1 is enough. It has nothing to do<br />

with having inequalties with large numbers of variables. Integer programming is hard because<br />

satisfying a set of constraints is hard. A careful study of the properties needed for a reduction can<br />

tell us a lot about the problem.<br />
