Single-Loop Multi-Objective Reliability-Based Design Optimization Using Chaos Control Theory and Shifting Vector with Differential Evolution

open access: yesMathematical and Computational Applications, 2023
Multi-objective reliability-based design optimization (MORBDO) is an efficient tool for generating reliable Pareto-optimal (PO) solutions. However, generating such PO solutions requires many function evaluations for reliability analysis, thereby ...

Multiplicative Approximations, Optimal Hypervolume Distributions, and the Choice of the Reference Point [PDF]

open access: yes, 2013
Many optimization problems arising in applications have to consider several objective functions at the same time. Evolutionary algorithms seem to be a very natural choice for dealing with multi-objective problems as the population of such an algorithm ...

An Improved S-Metric Selection Evolutionary Multi-Objective Algorithm With Adaptive Resource Allocation

open access: yesIEEE Access, 2018
One of the main disadvantages of evolutionary multi-objective algorithms (EMOAs) based on hypervolume is the computational cost of the hypervolume computation.

Directed Multiobjective Optimization Based on the Weighted Hypervolume Indicator [PDF]

open access: yesJournal of Multi-Criteria Decision Analysis, 2013
ABSTRACTRecently, there has been a large interest in set‐based evolutionary algorithms for multi objective optimization. They are based on the definition of indicators that characterize the quality of the current population while being compliant with the concept of Pareto‐optimality.

k-Pareto Optimality-Based Sorting with Maximization of Choice and Its Application to Genetic Optimization

open access: yesAlgorithms, 2022
Deterioration of the searchability of Pareto dominance-based, many-objective evolutionary optimization algorithms is a well-known problem. Alternative solutions, such as scalarization-based and indicator-based approaches, have been proposed in the ...

A Study of Archiving Strategies in Multi-Objective PSO for Molecular Docking [PDF]

open access: yes, 2016
Molecular docking is a complex optimization problem aimed at predicting the position of a ligand molecule in the active site of a receptor with the lowest binding energy. This problem can be formulated as a bi-objective optimization problem by minimizing

The Hypervolume Indicator Hessian Matrix: Analytical Expression, Computational Time Complexity, and Sparsity

open access: yes, 2023
The problem of approximating the Pareto front of a multiobjective optimization problem can be reformulated as the problem of finding a set that maximizes the hypervolume indicator. This paper establishes the analytical expression of the Hessian matrix of the mapping from a (fixed size) collection of $n$ points in the $d$-dimensional decision space (or $

Tri-objective parallel machine with job splitting and sequence dependent setup times using differential evolution and particle swarm optimization [PDF]

open access: yesInternational Journal of Industrial Engineering and Management
Parallel machines scheduling problems (PMSPs) exist in the industry since most manufacturing operations aim to produce lots of similar products in a defined time period. Some incoming jobs have different sizes and due dates; plus, the production capacity,

Towards efficient multiobjective optimization: multiobjective statistical criterions [PDF]

open access: yes, 2012
The use of Surrogate Based Optimization (SBO) is widely spread in engineering design to reduce the number of computational expensive simulations. However, "real-world" problems often consist of multiple, conflicting objectives leading to a set of ...
