I am working on a project about multi-reservoir control optimization problem and the objective function is calculated by Telemac simulator. Do you have some examples or best practices for such integration? I have read some JuMP examples and the objective function is written in expressions. Can I pass one function to @objective macro and can I get all variables in the function?
If your simulator can only return function evaluations, then JuMP isn’t the right tool for the job. Follow the link suggested by @tred for alternatives.
But if it can return derivative information, then you could consider using a user-defined function: Nonlinear Modeling · JuMP
Thanks for your quick reply. Follow the link you provide, I find the user-defined-function section: Nonlinear Modeling · JuMP. And the code snippet from Register a function section
square(x) = x^2
couple_with(x, y) = function .... get result from simultor... end
model = Model()
register(model, :square, 1, square; autodiff = true)
register(model, :couple_with, 2, f; autodiff = true)
@variable(model, x[1:2] >= 0.5)
@NLobjective(model, Min, couple_with(x[1], x[2]))
