Decision-dependent distributionally robust standard quadratic optimization with Wasserstein ambiguity

Immanuel M. Bomze, Daniel de Vicente, Abdel Lisser +1

The standard quadratic optimization problem (StQP) consists of minimizing a quadratic form over the standard simplex. Without assuming convexity or concavity of the quadratic form,…

The Maximum Clique Problem under Adversarial Uncertainty: a min-max approach

Immanuel Bomze, Chiara Faccio, Francesco Rinaldi +1

We analyze the problem of identifying large cliques in graphs that are affected by adversarial uncertainty. More specifically, we consider a new formulation, namely the adversarial…

Uncertain standard quadratic optimization under distributional assumptions: a chance-constrained epigraphic approach

Immanuel M. Bomze, Daniel de Vicente

The standard quadratic optimization problem (StQP) consists of minimizing a quadratic form over the standard simplex. Without convexity or concavity of the quadratic form, the StQP…

Feature selection in linear SVMs via a hard cardinality constraint: a scalable SDP decomposition approach

Immanuel Bomze, Federico D'Onofrio, Laura Palagi +1

In this paper, we study the embedded feature selection problem in linear Support Vector Machines (SVMs), in which a cardinality constraint is employed, leading to an interpretable…

Finding quadratic underestimators for optimal value functions of nonconvex all-quadratic problems via copositive optimization

Markus Gabl, Immanuel Bomze

Modeling parts of an optimization problem as an optimal value function that depends on a top-level decision variable is a regular occurrence in optimization and an essential ingred…
