I would like to use MTK to build a physical model and than use the equations and convert them into a JuMP model. Any ideas how to do that? My thoughs (based on Automatic Conversion of Julia Code to C Functions · Symbolics.jl ): This could be a method that takes an ODESystem and a JuMP.Model and at…

There’s a way to do this with an arbitrary differential equation stepper: https://mtk.sciml.ai/dev/tutorials/nonlinear_optimal_control/ It’s on the ControlSystem but easy to map over the ODESystem.

Thx! Do you mean the runge_kutta_discretize(sys::ControlSystem?

@ChrisRackauckas @ohmsweetohm1 Dear all, not sure this is the best place to ask but: what is the current state of MTK in terms of re-usability / translation towards other interfaces (such as JuMP) for optimisation? For instance: how can I use MTK and Ipopt?

[image] jbcaillau: For instance: how can I use MTK and Ipopt? MTK hooks into Optimization.jl. http://optimization.sciml.ai/stable/tutorials/symbolic/ Optimization.jl has an MOI interface to hit the JuMP solvers directly. http://optimization.sciml.ai/stable/optimization_packages/mathoptinte…

Thanks for the prompt answer: having a look at it.

Yes. Needs a bit more to do everything but it’s close
