Union of parameters

[Giovanni Pavese]

Hi!
I would like to know if it is possible to merge parameters defined for two different sets.

Suppose that I have a set A, a set B and a set C as C := A union B.
If I define param a{A} and param b{B}, is it possible to define something like  c{C} := a{A} union b{B} ?

Thank in advance for your patience.

You could define

param c {k in C} = if k in A then a[k] else b[k];

Note that if there is any member k of A that is also a member of B, then this places a[k] into c, but you could modify the expression to make a different choice.
