Hi,
I have to formulate a problem in mathprog where a variable can be both integer type and continuous type based on index.
Let me give an example to further illustrate this.
I have two sets of items:
set itemInteger;
set itemContinuous;
I need to define a variable, awardQuantity, on these sets so that for items in the set itemInteger, it is of type Integer and for items in set itemContinuous, it is of type continuous.
I know I can define two different variables:
var awardQuantityInt[i in itemInteger], integer;
var awardQuantityCont[i in itemContinuous];
But that is not what I am looking for.
I want a single variable handling both types.
I would really appreciate it if I can get some help on it. I have been trying to find an answer to this for a few days now.
Thanks,
Anku
