When MILP Beats QP: Piecewise-Linear Reformulations of Sequentially Coupled Bilinear Programs
Quentin Ploussard, Maris Usis, Oluwabunmi Iwakin +1
The presence of bilinear terms in mathematical modeling generally yields nonconvex quadratic programs (QPs) that remain computationally challenging to solve to global optimality. W…
