Hi

Is it possible to change constraints in a Constraint Programming modlel using OPL script?

I am aware of setCoef(dvar, coef)

However I receive the error  : Scripting runtime error: undefined method 'setCoef'

It seems setCoef only works for CPLEX models.

Thanks in advance

Dear Nicholas124,

I don't see a way to modify a constraint when using CP on OPL, since when you name a constraint 'foo', accessing it in OPL script using thisOplModel.foo will return null (instead of the constraint when using CPLEX).

As a workaround, I suggest that instead you modify the data from which your model is generated.

I hope this helps.

Cheers,
