May 1, 2021 · Summary. This chapter provides an overview of mixed-integer programming (MIP) modeling and solution methods.In Section 2.1, we present some preliminary concepts on optimization and mixed-integer programming. In Section 2.2, we discuss how binary variables can be used to model features commonly found in optimization problems. Jan 11, 2023 · Linear optimization problems that require some of the variables to be integers are called Mixed Integer Programs (MIPs). These variables can arise in a couple of ways: Integer variables that represent numbers of items, such as cars or television sets, and the problem is to decide how many of each item to manufacture in order to maximize profit.
