Hi,

(GLPK/MathProg / GMPL question)

I would like to subset param (e.g. param A{i in I,j in J} to param B{i
in I} i.e. dropping j index.

param A{i in I,j in J} >= 0, default 0;

param B{i in I} >= 0, default 0;

###########
The data

The input,

param A:=
1 3 40.1
2 5 50.2
3 6 35.3
.

Result would be like this:

param B:=
1 40.1
2 50.2
3 35.3
.

##########

What would be param B{i in I}:=?

Any other suggestion how get create param B{i in I} from param A{i in
I,j in J}.

#param B{i in I} >= 0, default 0;

param B{i in I}:= ?

Thanks.

Noli
