Minimum penalized φ-divergence estimation under model misspecification
(MDPI, 2018-04-30)
This paper focuses on the consequences of assuming a wrong model for multinomial data when using minimum penalized φ-divergence, also known as minimum penalized disparity estimators, to estimate the model parameters. These ...

Solving multifacility Huff location models on networks using metaheuristic and exact approaches
(PERGAMON-ELSEVIER SCIENCE LTD, 2016-03-16)
In this paper we consider multifacility Huff facility location problem on networks. First, we introduce a slight modification of the existing mixed integer nonlinear mathematical model and confirm its validity by using the ...

A discretization result for some optimization problems in framework spaces with polyhedral obstacles and the Manhattan metric
(Elsevier, 2018-07)
In this work we consider the shortest path problem and the single facility Weber location problem in any real space of finite dimension where there exist different types of polyhedral obstacles or forbidden regions. These ...

Chasing cardiac physiology and pathology down the CaMKII cascade
(American Physiological Society, 2015-05-15)
Calcium dynamics is central in cardiac physiology, as the key event leading to the excitation-contraction coupling (ECC) and relaxation processes. The primary function of Ca2+ in the heart is the control of mechanical ...

New efficiency conditions for multiobjective interval-valued programming problems
(Elsevier, 2017)
In this paper, we focus on necessary and sufficient efficiency conditions for optimization problems with multiple objectives and a feasible set defined by interval-valued functions. A new concept of Fritz-John and ...

On minimax and Pareto optimal security payoffs in multicriteria games
(Elsevier, 2018)
In this paper, we characterize minimax and Pareto-optimal security payoff vectors for general multicriteria zero-sum matrix games, using properties similar to the ones that have been used in the single criterion case. ...

Sum-of-squares clustering on networks
(University of Belgrade, 2011)
Finding p prototypes by minimizing the sum of the squared distances from a set of points to its closest prototype is a well-studied problem in clustering, data analysis and continuous location. In this note, this very ...

Pareto optimality conditions and duality for vector quadratic fractional optimization problems
(Hindawi, 2014)
One of the most important optimality conditions to aid in solving a vector optimization problem is the first-order necessary optimality condition that generalizes the Karush-Kuhn-Tucker condition. However, to obtain the ...
