Aggregations of quadratic inequalities and hidden hyperplane convexity
Grigoriy Blekherman, Santanu S. Dey, Shengding Sun
We study properties of the convex hull of a set described by quadratic inequalities. A simple way of generating inequalities valid on is to take a nonnegative linear combin…
Exploiting Instance and Variable Similarity to Improve Learning-Enhanced Branching
Xiaoyi Gu, Santanu S. Dey, Álinson S. Xavier +1
In many operational applications, it is necessary to routinely find, within a very limited time window, provably good solutions to challenging mixed-integer linear programming (MIL…
Solving sparse separable bilinear programs using lifted bilinear cover inequalities
Xiaoyi Gu, Santanu S. Dey, Jean-Philippe P. Richard
Recently, we proposed a class of inequalities called lifted bilinear cover inequalities, which are second-order cone representable convex inequalities, and are valid for a set desc…
