[Help-glpk] More conditional variables fun

[Yaron Kretchmer]

Hi There.
Using feedback I got from the mailing list, I was able to formulate binary conditional variables. 

Now I'd like to be able to model conditional non-binary variables. Does anybody know how to formulate this in mathprog?

----------Begin Description -------------------
*) a,b are binary
*) c,d,e is continuous.
*) I'd like c to be 
    - 0 if a=b=0
    - d if a=0,b=1
    - e if a=1,b=0
    - 0 if a=b=1
----------End Description


Thanks much
Kretch
