Piecewise Polyhedral Formulations for a Multilinear Term
Kaarthik Sundar, Harsha Nagarajan, Jeff Linderoth +2
In this paper, we present a mixed-integer linear programming (MILP) formulation of a piecewise, polyhedral relaxation (PPR) of a multilinear term using its convex hull representati…

An Adaptive, Multivariate Partitioning Algorithm for Global Optimization of Nonconvex Programs
Harsha Nagarajan, Mowen Lu, Site Wang +2
In this work, we develop an adaptive, multivariate partitioning algorithm for solving mixed-integer nonlinear programs (MINLP) with multi-linear terms to global optimality. This it…
