How binary variables can be modeled using continuous variables?

Hello, Is it possible to mathematically model a binary variable using continuous variables in the optimization problems? For example, assume that 'X' is {0,1}. Can I define it as 0

Does the multiplication of a binary variable by a real variable make the resultant expression 'Nonlinear' or 'Integer/Discrete'?

Binary Variable * Real Variable = ? 1) lead to an equivalent 'Nonlinear' variable (and thus => MINLP), 2) lead to an equivalent 'Integer' variable, 'Discrete' I mean (and thus =>...

What is the concept of the "Nonanticipativity Constraint" in Stochastic Programming?

NONANTICIPATIVITY As far as I know, decision making under uncertainty can often be formalized as a stochastic problem. I have seen a constraint which is called "Nonanticipativity" in the most...

How can I model a constraint in the meta-heuristic algorithms (e.g., GA, PSO, GSA, etc.)?

Hello, As far as I know, the meta-heuristic algorithms such as GA, PSO, GSA, etc. generally find the optimal solution of 'unconstrained' optimization problems. If I have some constrains (equality...

Could we possibly call a function in GAMS similar to what we do in MATLAB?

I am going to call a function (an external GAMS code) to my main GAMS code. In MATLAB, it is really convenient to call an m-file as a function (an external m-file code I mean) to the main program....
