got problem on set definition in Gams, how to model this simple case in Gams?

GAMS
1

initialize k=0, R is an empty set;

repeat
k=k+1;
R is R∪{k};
Until k=100;

can any1 show me the example code in Gams for this case?

Thank you

Hi Songming



You could do as follows:



Set overall /n1*n1000/,

k(overall) ;



Loop(overall$(ord(overall) < 101),

k(overall) = YES;

);



Cheers

thank you for your answer
I have one more question about this case

scalars
k /0/;
positive variables x;
variables obj;
equations
objective;
objective… obj=e=x+k;
model case /all/;
repeat (
k=k+1;
solve case using lp minimizing obj;
Until k=200
);

Now I need to collect all of the solutions into one solution pool, create a new parameter, and use the solution pool as the new parameter for the following calculation, how can I do?

Sincerely
