Thanks heaps

Change Equation over time

I am trying to update the DICE2013 model in GAMS. I want to solve parts of it recursively. If I have an equation like the one below, how can I tell GAMS that after, say 5 periods t, it should update the equation? I(t) =E= S(t) * Y(t); So that after 5 periods, the function for example becomes: I(t) =...

Indexing a Set with multiple values

Hi there, I'm trying some alteration to the DICE2013 model. I define a set of a hundred values and want to access one value for each period t. I.e. if t=5, I want GAMS to return the fifth value in the parameter cereq. sets t Time periods (5 years per period) / 1*100 / cereq list of multipliers /v1*v...
