Setting constraints with variables as exponents in PySCIPOpt

I want to solve an MINLP problem with SCIP in Python and therefore use PySCIPOpt. I already introduced the variables, the objective function, and set the constraints (as far as it was possible, given my issue). Within one constraint, there is a…

How to use PySCIPOpt for feasibility-only problem

I have used CVXPY and some of its LP solvers to determine whether a solution to an A*x <= b problem is feasible, and now I would like to try PySCIPOpt. I could not find an example of this in the docs, and I'm having trouble figuring out the right…

Is there a better way to solve this MINLP in pyscipopt?

I'm trying to solve the following MINLP, basically attempting to maximize the likelihood of a certain portfolio reaching a "ceiling" performance. My first attempt at the code is below. EDIT: Math says maximize, should say minimize from pyscipopt…

In pyscipopt, would it be possible to use a function containing an optimization model inside of my main optimization model?

I am using Jupyter Notebook. I have tried defining a function with an optimization model, it seems to work outside of my main model. When I tried using the function on a variable inside my main model, at first the kernel dies, when I have updated…
