Polyhedral extended formulations that approximate the Gomory closure for packing problems

Friedrich Eisenbrand, Samuel Fiorini, Lars Rohwedder +1

We consider $0/1$ packing problems $max {c^{T} x : A x \leq 1, x \in {0, 1}^{n}}$ , with $A \in R_{\geq 0}^{m \times n}$ . A way to solve such problems is via tighteni…

Excluding a Line Minor via Design Matrices and Column Number Bounds for the Circuit Imbalance Measure

Daniel Dadush, Friedrich Eisenbrand, Rom Pinchasi +2

For a real matrix $A \in R^{d \times n}$ with non-collinear columns, we show that $n \leq O (d^{4} κ_{A})$ where $κ_{A}$ is the \emph{circuit imbalance measure} of $A$ . The circu…

Integer linear programming for unsupervised training set selection in molecular machine learning

Matthieu Haeberle, Puck van Gerwen, Ruben Laplaza +4

Integer linear programming (ILP) is an elegant approach to solve linear optimization problems, naturally described using integer decision variables. Within the context of physics-i…
