Another thing, it is supposed to be an equilibrium model

Thanks. Sorry for double message.

Thanks for your insight.

My solution shouldn’t be integers. And to change it to MIP model could be painful for me.

Does icut also cover non MIP?

Sungai,

You should have a look at the models in the GAMS model library. For

example, the model icut has a solve within a loop, etc.

Hello all,

I am a beginner, trying to write this in GAMS.

I have a set t(time) and other sets and I want to calculate something that

is growing over time.

p(0) (p at t = 0) is the initial value.

X is the growing factor, a constant.

O(a,b) is a variables that needs to be optimized over time period, a and b

is set names

So I wrote something like:

//the empty lines contains model

//…

//…

model mymodel/ALL;

loop(t,

solve problem maximizing my objective function; // to get O(a,b)

and other variables

p(t) = (1+X) * p(t-1) - O(a,b,t-1);

);

I know how to do this in C/C++ with while do loop or for loop, but I am not

familiar yet with GAMS syntax.

Thanks.

regards,

sungai.
