dynamic constraint for non-consecutive years
#1
Hi, 
 I wonder if it is possible to impose a growth constraint with the form: 
                   var_act(t) * growth(t) >= var_act(t+2) - seed

The manual talks only about dynamic constraints of type (t,t+1) and (t,t-1).

Motivation: my model has some maximum growth and decline constraints on historical data, but as demand shrunk in 2020 due to the global crisis, I cannot impose decline constraints in this year. So one solution would be to impose constraints in the difference between 2021 (when the economy recovers) and 2019.

Yes, it is possible at least with a cumulative constraint. Reading the following thread should give you the idea, or two:
