Transformation-based preprocessing for mixed-integer quadratic programs. (English) Zbl 1338.90276
Summary: This paper presents two preprocessing techniques for mixed-integer quadratic programs with non-convex objective functions, where the continuous part of the Hessian is invertible. The techniques aim at reducing the number of bilinear terms in the objective. Results show that one of the techniques decreases the solution times once the reduction in bilinear terms crosses a threshold.
