how to decrease the running time for a sequence optimisation
Awaiting user inputHello, I got an optimisation problem that requires finding out the min/max value of the system at each time step (hourly) for 24 hours. The process is like, e.g., when the problem has to be optimi...

why using gurobi solver in loop could cause increase the optimisation time.
Answeredi was solving a optimisation problem based on sequential case. I have run the model for 24 times (24 time steps in my model and I have to obtain the optimal solution for each time step). Previously...

how can I get constraints
AnsweredHi, I got some constraints as: I want to get them by using getConstrByName(), however, this method chooses one arbitrarily. So is there any other way helps to obtain all constraints with the same n...

infeasibility occurred after using the solution as input
Awaiting user inputHi Just a very wired issue happened to my case. My previous problem was finding the minimum cost of the system, considering the operation of each component. Then I got the solution and wanted to ...

is there any approach to speed up the LP optimization?
Awaiting user inputHi, I am using piecewise linearization to simplify a MINLP problem. This problem was solved by several months ago, by using second order cone programming as a relaxation approach. However, when I ...

How to linearize the nonlinear constraint in modelling
Answeredhi gurobi teams: I am trying to use PWL method on tackling my nonlinear constraints, e.g., z^2=x^2-y^2 I have went through an example on the gurobi portal and found this: import gurobipy as gpfrom ...
