Hi Jaromił, Thank you so much for your clear answers. I will definitely have a look at the webinar and the tech talk!I do have one last question, which is about the local minima.I have one quadrati...

Hi Jaromił, Thanks again for this extensive answer. I chose to include the quadratic function because, in my view, the linearization led to a significant error. I do indeed have a nonconvex continu...

Hi Jaromił,Thanks for the extensive answer. I am not sure if it really answers my question, let me try to rephrase. I have developed a model with one quadratic constraint. It is a model used to sim...

Computational complexity of MILP vs MIQP model
AnsweredDear,I was wondering about the inherent computational complexity of MIQP vs MILP models.I am not sure if the following formulation is correct, but:If we assume that there are two models consisting ...

Hi Eli,Thanks so much for your quick response, it is really appreciated. I think this works perfectly! In this context, the coefficient c translates the on-off status to a degradation penalty. In m...

Quicksum in constraint leads to too many nonzeros
OngoingDear,I want to model a power system in which the performance characteristics are affected by its usage through degradation. I am minimising fuel consumption over time [t].I modelled the on/off stat...
