Observation thinning in data assimilation computations

open access: yesEURO Journal on Computational Optimization, 2015
We propose to use an observation-thinning method for the efficient numerical solution of large-scale incremental four- dimensional (4D-Var) data assimilation problems.

Optimal Release Time Decision from Fuzzy Mathematical Programming Perspective

open access: yes, 2015
Demand for high software reliability requires rigorous testing followed by requirement of robust modeling techniques for software quality prediction. On one side, firms have to steadily manage the reliability by testing it vigorously, the optimal release

A Subgradient Method for Free Material Design [PDF]

open access: yes, 2016
A small improvement in the structure of the material could save the manufactory a lot of money. The free material design can be formulated as an optimization problem.

Complementarity-based nonlinear programming techniques for optimal mixing in gas networks

open access: yesEURO Journal on Computational Optimization, 2019
We consider nonlinear and nonsmooth mixing aspects in gas transport optimization problems. As mixed-integer reformulations of pooling-type mixing models already render small-size instances computationally intractable, we investigate the applicability of ...

An interior-point method for nonlinear optimization problems with locatable and separable nonsmoothness

open access: yesEURO Journal on Computational Optimization, 2015
Many real-world optimization models comprise nonconvex and nonsmooth functions leading to very hard classes of optimization models. In this article, a new interior-point method for the special, but practically relevant class of optimization problems with

The role of child language ability and parental mentalization in early child dysregulation

open access: yesInfant Mental Health Journal: Infancy and Early Childhood, Volume 47, Issue 1, January 2026.
Abstract Dysregulation in early childhood is associated with increased vulnerability to psychopathology and poor psychosocial outcomes. While there is evidence that both child language ability and parental mentalization are associated with dysregulation in early childhood, there is little understanding of the relationships between these variables, and ...

Solving wind farm layout optimization with mixed integer programs and constraint programs

open access: yesEURO Journal on Computational Optimization, 2014
The wind farm layout optimization problem is concerned with the optimal location of turbines within a fixed geographical area to maximize profit under stochastic wind conditions. Previously, it has been modeled as a maximum diversity (or p-dispersion-sum)

Comparative efficacy of selenoureido carbonic anhydrase inhibitors and azole antifungal drugs against clinical isolates of Malassezia pachydermatis

open access: yesVeterinary Dermatology, Volume 36, Issue 3, Page 302-313, June 2025.
Background – Malassezia pachydermatis (MP) is implicated in severe dermatitis and otitis externa (OE) of companion animals and recently gained attention for its increasing resistance to azole compounds. For this reason, developing novel therapeutic strategies is of great interest. In a previous work, we used reference yeast isolates to evaluate several

Tighter MIP formulations for the discretised unit commitment problem with min-stop ramping constraints

open access: yesEURO Journal on Computational Optimization, 2017
This paper elaborates compact MIP formulations for a discrete unit commitment problem with minimum stop and ramping constraints. The variables can be defined in two different ways.

A continuation method for the efficient solution of parametric optimization problems in kinetic model reduction

open access: yes, 2013
Model reduction methods often aim at an identification of slow invariant manifolds in the state space of dynamical systems modeled by ordinary differential equations.
