11 Formulating and Solving Integer Programs
www.lindo.comIn a pure integer program, all variables are restricted to integer values. In a mixed formulation, only certain of the variables are integer; whereas, the rest are allowed to be continuous. 0/1 vs. general. In many applications, the only integer values allowed are 0/1. Therefore, some integer programming codes assume integer variables are ...
Integer Linear Programs - AMPL
ampl.comSince the model has a combination of continuous (non-integer) and integer variables, it yields what is known as a ‘‘mixed-integer’’ program. To complete the model, we need to add constraints to assure thatTransand Useare related in the intended way. This is the ‘‘clever’’ part of the formulation; we simply
