Interactive Multiobjective Procedure for Mixed Problems and Its Application to Capacity Planning [PDF]

open access: yesEntropy, 2021
A problem that appears in many decision models is that of the simultaneous occurrence of deterministic, stochastic, and fuzzy values in the set of multidimensional evaluations. Such problems will be called mixed problems.

Probing Modified Gravity Theories with Scalar Fields Using Black-Hole Images

open access: yesUniverse, 2023
We study a number of well-motivated theories of modified gravity with the common overarching theme that they predict the existence of compact objects, such as black holes and wormholes endowed with scalar hair.

Nonlinear instability and scalar clouds of spherical exotic compact objects in scalar-Gauss-Bonnet theory

open access: yesEuropean Physical Journal C: Particles and Fields, 2023
In this work, we present a new type of scalar clouds supported by spherically symmetric horizonless compact objects in the scalar-Gauss–Bonnet theory.

Nonconvex Vector Optimization and Optimality Conditions for Proper Efficiency

open access: yesInternational Journal of Analysis and Applications, 2022
In this paper, we consider, a new nonlinear scalarization function in vector spaces which is a generalization of the oriented distance function. Using the algebraic type of closure, which is called vector closure, we introduce the algebraic boundary of a

A generalization of interval-valued optimization problems and optimality conditions by using scalarization and subdifferentials

open access: yesKuwait Journal of Science, 2021
In this work, interval-valued optimization problems are considered. Ordering cone is used in order to obtain a generalization of interval-valued optimization problems on real topological vector spaces.

IDOL: A web application for mixed integer linear multiobjective optimization

open access: yesSoftwareX, 2022
Practical decision-making very often results in complex multiobjective optimization problems that can be solved only by advanced software. At present, it is available for singleobjective optimization and much less for multiobjective optimization ...

The concept of B-efficient solution in fair multiobjective optimization problems [PDF]

open access: yesIranian Journal of Numerical Analysis and Optimization, 2017
A problem that sometimes occurs in multiobjective optimization is the existence of a large set of fairly effcient solutions. Hence, the decision making based on selecting a unique preferred solution is diffcult.

A review of multi-objective optimization: Methods and its applications

open access: yesCogent Engineering, 2018
Several reviews have been made regarding the methods and application of multi-objective optimization (MOO). There are two methods of MOO that do not require complicated mathematical equations, so the problem becomes simple.
