hello all ,
i am trying to a solve a mip problem where the output is a array of variables d= [d0,d1,d2,d3] and all combinations of these variables.(maximum 2 variables at a time ). like d0+ d1 , d0 d3 .. , obviously d0,d1,d2,d3 ... and so on . but cplex does not give some of the combinations like for example it misses d0 d2 ....

when i fix the array d = [1,2,4,6] for example ... cplex gives me all the combinations ...
can some one help me out ?

Arush.
