Comparison of Some Scalarization Methods in Multiobjective Optimization: Comparison of Scalarization Methods
Kasımbeyli, Refail; Öztürk, Zehra Kamışlı; Kasımbeyli, Nergiz; Yalçın, Gülçin Dinç; Erdem, Banu Icmen (Malaysian Mathematical Sciences Soc, 2019)The paper presents an analysis, characterizations and comparison of six commonly used scalarization methods in multiobjective optimization. The properties of these methods are investigated with respect to the basic ... -
A coradiant based scalarization to characterize approximate solutions of vector optimization problems with variable ordering structures
Sayadi-bander, Abbas; Kasımbeyli, Refail; Pourkarimi, L. (Elsevier Science BV, 2017)This paper investigates some properties of approximate efficiency in variable ordering structures where the variable ordering structure is given by a special set valued map. We characterize epsilon-minimal and epsilon- ... -
Coradiant sets and -efficiency in multiobjective optimization
Sayadi-bander, Abbas; Pourkarimi, Latif; Kasımbeyli, Refail; Basirzadeh, Hadi (Springer, 2017)This paper studies -efficiency in multiobjective optimization by using the so-called coradiant sets. Motivated by the nonlinear separation property for cones, a similar separation property for coradiant sets is investigated. ... -
A generalization of a theorem of Arrow, Barankin and Blackwell to a nonconvex case
Kasımbeyli, Nergiz; Kasımbeyli, Refail; Mammadov, Musa (Taylor & Francis LTD, 2016)The paper presents a generalization of a known density theorem of Arrow, Barankin, and Blackwell for properly efficient points defined as support points of sets with respect to monotonically increasing sublinear functions. ... -
Hartley properly and super nondominated solutions in vector optimization with a variable ordering structure
Shahbeyk, Shokouh; Soleimani-damaneh, Majid; Kasımbeyli, Refail (Springer, 2018)In this paper, we introduce Hartley properly and super nondominated solutions in vector optimization with a variable ordering structure. We prove the connections between Benson properly nondominated, Hartley properly ... -
An incremental piecewise linear classifier based on polyhedral conic separation
Öztürk, Gürkan; Bagirov, Adil M.; Kasımbeyli, Refail (Springer, 2015)In this paper, a piecewise linear classifier based on polyhedral conic separation is developed. This classifier builds nonlinear boundaries between classes using polyhedral conic functions. Since the number of polyhedral ... -
New mathematical models for team formation of sports clubs before the match
Budak, Gercek; Kara, İmdat; Ic, Yusuf Tansel; Kasımbeyli, Refail (Springer, 2019)Coaches of sports clubs aim to form the team that optimally determines the roles of positions before the match. These types of decisions are referred to as the team formation problem, and they are critical for the sports ... -
A novel piecewise linear classifier based on polyhedral conic and max-min separabilities
Bagirov, Adil M.; Ugon, Julien; Webb, Dean; Öztürk, Gürkan; Kasımbeyli, Refail (Springer, 2013)In this paper, an algorithm for finding piecewise linear boundaries between pattern classes is developed. This algorithm consists of two main stages. In the first stage, a polyhedral conic set is used to identify data ... -
Optimality conditions via generalized radial epiderivatives in nonconvex set-valued optimization
Kasımbeyli, Refail; İnceoğlu, G. (Vilnius Gediminas Technical University, 2010)In this paper, the generalized radial epiderivative for set-valued maps is introduced and its relationship to the radial epiderivative is investigated. Existence conditions for generalized radial epiderivatives are established ... -
