Thank you .a) Yes I have a jupyter-notebook (ipynb) file that I can share which models the ACOPF (AC optiamal power flow) but the results using IPOPT are infeasible for no reason. Would you like me...

Nonconvex problem considered convex by Pyomo/ Gurobi solver ! Weird?
Awaiting user inputQUESTION 1: We have an optimization problem with objective function f(x,y,z,p) = 0.12 * x^2 + 14.8 * x + 89 + 0.17 * y^2 + 16.57 * y + 83 + 0.15 * z^2 + 15.55 * z + 100 + 0.19 * p^2 + 16.21 * p + ...
