ok, I'll try then. One more question. Since I want to use QP solver many times, is there any other suggestion to accelerate the optimization speed? I'm wondering if some operation (like initiating ...

Yes, the QP optimization is actually a part of a larger context. Do you mean it does not support warm-start in the QP barrier method? Even if I change GRB_DoubleAttr_Start, it still cannot affect t...

Is it possible for QP method to change the target function dynamically?
進行中I'm trying QP solver now. And I'm curious about if we can change the objective function in each iteration. If so, how to deal with it? is it possible to add a callback function and change the objec...

ok, I'll try them later. But I'm curious that some other solvers claim they can handle non-PSD quadratic programming. Why gurobi solver has to convert the problem to a MIP problem? is there any the...

Hi, Najman. I have tried just now. When setting GRB_IntParam_NonConvex=2, the gurobi solver decided to solve as a MIP, and the speed was too slow. Any more ideas for solving non-PSD quadratic progr...

Thank you very much for your fast reply. One more question, is gurobi able to handle the non-PSD problem? I have tried one, but it returns like this: Error code = 10020Objective Q not PSD

initial value of quadratic programming.
回答済みI wonder whether the initial value will affect the result of quadratic programming. If so, how to set the initial value in c++?
