On disjunction convex hulls for generalized cross polytopes

Yushan Qu, Jon Lee

We continue the study of the natural polytope $D$ in $R^{n + d}$ associated with the disjunction of a set of $n + 1$ polytopes in $R^{d}$ , managed by $n$ bina…

On disjunction convex hulls by lifting

Yushan Qu, Jon Lee

We study the natural extended-variable formulation for the disjunction of $n + 1$ polytopes in $R^{d}$ . We demonstrate that the convex hull $D$ in the natural extended-variabl…
