To learn more, see our tips on writing great answers. However, if we want prompt results, are willing to settle with decent solutions with limited computing resources, or typically work on tasks with data of lower dimensions, then there may not be a need to incorporate MIQP. Solving the XY Model using Mixed Integer Optimization in Python This example constructs a sequence of MILP problems that satisfy the constraints, and that increasingly approximate the quadratic objective function.

How Scheduling work with new Android Jetpack component WorkManager? Abstract This paper considers mixed-integer quadratic programs in which the objective function is quadratic in the integer and in the continuous variables, and the constraints are linear in the variables of both types. Based on the above, we have shown how optimization can be used to perform feature selection on linear regression problems. In this paper, we prove that the decision version of mixed-integer quadratic programming is in NP, thereby showing that it is NP-complete. Thank you for your ansmer !
