GAMM-Mitteilungen, Volume 47, Issue 4, November 2024.Abstract This paper provides an overview of current approaches for solving inverse problems in imaging using variational methods and machine learning. A special focus lies on point estimators and their robustness against adversarial perturbations. In this context results of numerical experiments for a one‐dimensional toy problem are provided, showing ...

KT-invexity in optimal control problems
, 2009 We extend the notion of KT-invexity from mathematical programming to the classical optimal control problem and show that this generalized invexity property is not only a sufficient condition of optimality for KT-processes (processes that obey KT ...

Clinical and Experimental Dental Research, Volume 10, Issue 5, October 2024.ABSTRACT Objective This study assessed the effect of the anodization of titanium abutments on the color parameters and color difference of lithium disilicate (LDS) all‐ceramic crowns. Materials and Methods In this study, 19 straight abutments were divided into two groups: anodized (n = 9) and non‐anodized control (n = 9), with one hybrid zirconia ...

On constraint qualifications with generalized convexity and optimality conditions [PDF]
This paper deals with a multiobjective programming problem involving both equality constraints in infinite dimensional spaces. It is shown that some constraint qualifications together with a condition of interior points are sufficient conditions for the ...

Continuous-time optimization problems involving invex functions
, 2007 In [D.H. Martin, The essence of invexity, J. Optim. Theory Appl. 47 (1985) 65–76] Martin introduced the notions of KKT-invexity and WD-invexity for mathematical programming problems. These notions are relaxations of invexity.

Sumatriptan‐naproxen sodium in migraine: A review
European Journal of Neurology, Volume 31, Issue S2, September 2024.Abstract Background Varied responses to acute migraine medications have been observed, with over one‐third (34.5%) of patients reporting insufficient headache relief. Sumatriptan‐naproxen sodium, a single, fixed‐dose combination tablet comprising sumatriptan 85 mg and naproxen sodium 500 mg, was developed with the rationale of targeting multiple ...

Necessary and Sufficient Second-Order Optimality Conditions on Hadamard Manifolds
Mathematics, 2020 This work is intended to lead a study of necessary and sufficient optimality conditions for scalar optimization problems on Hadamard manifolds. In the context of this geometry, we obtain and present new function types characterized by the property of ...

Fritz John type optimality and duality in nonlinear programming under weak pseudo-invexity [PDF]
, 2015 In this paper, we use a generalized Fritz John condition to derive optimality conditions and duality results for a nonlinear programming with inequality constraints, under weak invexity with respect to different (ηi)i assumption.

Second and higher order duality in Banach space under -invexity
, 2011 In this paper, we introduce the concept of second and higher order duality in Banach space using ρ-(η,θ)-invexity type conditions. Duality theorems for Mangasarian type, Mond-Weir type are established under weaker conditions.

Optimality Condition and Wolfe Duality for Invex Interval-Valued Nonlinear Programming Problems
Journal of Applied Mathematics, 2013 The concepts of preinvex and invex are extended to the interval-valued functions. Under the assumption of invexity, the Karush-Kuhn-Tucker optimality sufficient and necessary conditions for interval-valued nonlinear programming problems are derived ...
