WebAs introduced in the topic Stating a MIP problem , a mixed integer programming (MIP) problem can contain both integer and continuous variables. If the problem contains an objective function with no quadratic term, (a linear objective), and all the constraints are linear, then the problem is termed a Mixed Integer Linear Program (MILP). http://web.mit.edu/16.410/www/lectures_fall04/L18-19-IP-BB.pdf
