Enhancements of discretization approaches for non-convex mixed-integer quadratically constrained quadratic programming: Part I

Beach, Benjamin; Burlacu, Robert; Bärmann, Andreas; … - In: Computational Optimization and Applications 87 (2024) 3, pp. 835-891

We study mixed-integer programming (MIP) relaxation techniques for the solution of non-convex mixed-integer quadratically constrained quadratic programs (MIQCQPs). We present MIP relaxation methods for non-convex continuous variable products. In this paper, we consider MIP relaxations based on...

Enhancements of discretization approaches for non-convex mixed-integer quadratically constrained quadratic programming: Part II

Beach, Benjamin; Burlacu, Robert; Bärmann, Andreas; … - In: Computational Optimization and Applications 87 (2024) 3, pp. 893-934

This is Part II of a study on mixed-integer programming (MIP) relaxation techniques for the solution of non-convex mixed-integer quadratically constrained quadratic programs (MIQCQPs). We set the focus on MIP relaxation methods for non-convex continuous variable products where both variables are...
