They are called variables because the represented information can change but the operations on the variable remain the same. Variables form the basis of programming. Every Scilab script, function or routine that we need to write will contain for sure variables. In general, a program should be written with "Symbolic" notation, such that a statement is always true symbolically. The variable also can be used by any function at any time. If values are variable they can be changed by the program and the user. A variable, in the context of programming, is a symbolic name given to an unknown quantity that permits the name to be used independent of the information it represents. The original ASP(LC) language allows objective functions of Boolean variables only, but integer variables are more convenient than Booleans in many applications [11].
