Well, I have seen at least 6 different ways of coding the simplex method, but still I have a question. All of these editions suppose that the solution vector consist of variables of the same type.
In my issue there are two types of variables: the set power of machines (which is continuous double value) and the state variable, where 0 - machine is off, 1 - machine is on.
Maybe, someone faced a similar task and now can explain me possible solution.
