Using Semi-Continuous Variables
Semi-continuous variables are variables that may take either the value 0 or values in a finite range [a, b]. Semi-continuous variables can be specified in MPS and LP files. In the Concert Technology Library, semi-continuous variables are instances of the class IloSemiContVar. In the Callable Library, semi-continuous variables can be entered with type CPX_SEMICONT or CPX_SEMIINT via the routine CPXcopycttype().
