Mixed Integer Programming Problem:Some variables are restricted to be integers; the others can take any value. Binary Integer Programming Problem:All variables are restricted to be 0 or 1. There are two main reasons for using integer variables when modeling problems as a linear program: 1. The integer variables represent quantities that can only be integer. For example, it is not possible to build 3.7 cars. 2. The integer variables represent decisions (e.g. whether to include an edge in a graph) and so should only take on the value 0 or 1. small bedrooms on a budget
