[Help-glpk] Slices

[Nilo Cesar Teixeira]

Hi all,

Is it possible to define a slice in which the non-asterisk indexes are sets ?

Let's say:

set S := {i in 1..10};

set M := M1 M2;

param QUOTA{M, S} integer;

data;

param QUOTA :=

[*, 1]

M1 4

        M2 10

[*, 2]

M1 4

        M2 10

[*, 3]

M1 4

        M2 10;

end;

...so in this example, the desired slice would be [*, {1..3}]

A workaround I thought is to define subsets which partition the values to be assigned and then define QUOTA for each of those subsets, but that's not a nice solution IMHO (better than duplicating though).

Thanks.
