Zero-one integer programming (which can also be written as '0-1' integer programming) is a mathematical method of using a series of binary functions. It uses yes ('1') and no ('0') answers to arrive at a solution when there are two mutually exclusive options.

In the world of finance, zero-one integer programming is often used to provide answers to capital rationing problems, as well as to optimize investment returns and assist in planning, production, transportation, and other issues.
