Compact mixed-integer programming relaxations in quadratic optimization
Ben Beach, Robert Hildebrand, Joey Huchette
We present a technique for producing valid dual bounds for nonconvex quadratic optimization problems. The approach leverages an elegant piecewise linear approximation for univariat…

An Approximate Method for the Optimization of Long-Horizon Tank Blending and Scheduling Operations
Benjamin Beach, Robert Hildebrand, Kimberly Ellis +1
We address a challenging tank blending and scheduling problem regarding operations for a chemical plant. We model the problem as a nonconvex MIQCP, then approximate this model as a…
