Axis-Aligned Relaxations for Mixed-Integer Nonlinear Programming
Haisheng Zhu, Taotao He, Mohit Tawarmalani
We present a novel relaxation framework for general mixed-integer nonlinear programming (MINLP) grounded in computational geometry. Our approach constructs polyhedral relaxations b…

Extracting structure from functional expressions for continuous and discrete relaxations of MINLP
Taotao He, Mohit Tawarmalani
In this paper, we develop new continuous and discrete relaxations for nonlinear expressions in an MINLP. In contrast to factorable programming, our techniques utilize the inner-fun…
