Hi, I have a decision variable x[t], if (x[t]==1 && xt-1==0) {...}. But there is an error "decision variable not allowed". But when I use help, it says "Implications of constraints can be used instead when conditions contain decision variables". What can I do? Thank you very much.

Hi

instead of writing

if (x[t]==1 && x[t-1]==0) { y[t]==2; }

you should for instance write

(x[t]==1 && x[t-1]==0) =>  (y[t]==2);

Regards

Can I use loop after =>?
For example, (x[t]==1 && xt-1==0) => (forall (t in 1..nbTime) {y[t]==2})
Thank you.
