Joint-Range Inequalities for Nonconvex QCQPs
Liding Xu, Sebastian Pokutta
We study cutting planes for nonconvex quadratically constrained quadratic programs (QCQPs) through a project-then-lift approach inspired by mixed-integer rounding (MIR) inequalitie…

Agentic MIP Research: Accelerated Constraint Handler Generation
Liding Xu, Yugeng Zhou, Sebastian Pokutta
Mixed-integer programming (MIP) research is both mathematically sophisticated and engineering-intensive: testing an algorithmic hypothesis within a branch-and-cut solver requires s…
