optimization with interdependent variables?
显示 更早的评论
I am using fgoalattain for a multi-objective optimization problem. In this problem, I have some parameter (x) that is dependent on two other variables (y,z). And one of those two variables (y) is dependent on the other (z). So, basically I need to do optimization on two levels for these two variables. How can I do that?
Thanks

Huh?
If x is dependent on the other variables, y and z, then it is NOT something you can independently vary.
Similarly, if y is dependent on z, then it is also not an independent variable.
As such, you have a ONE variable problem. y is a DEPENDENT variable. It is not something you can vary, except by varying z. The same applies to x.

Nonlinear constraints on the independent variables y and z. It is not clear whether x is also an independent variable that you would nonlinear constraint

Optimize with respect to z.
Anything that depend on z, including y and x, such as objectve, constraints, upper bounds..., can be written as function of z.
