[Help-glpk] Calculate model parameter in a for loop in GMPL

[OYO1]

Hi All,

How can I calculate a model parameter in a for loop in GMPL? I tried the
code below but id did not work.

set T := 1..10;
set D := 1..20;

param s{T} := 0;
param g{D} := trunc(Uniform(1, 11));

# compute the size
 forall{d in D}: s[g[d]] = s[g[d]]+1;


After the for loop the value of the s[] parameter is still zero for all
indices.
