Error analysis of elitist randomized search heuristics [PDF]

open access: yesSwarm and Evolutionary Computation, 2021
For complicated problems that cannot be solved in polynomial first hitting time (FHT)/running time(RT), a remedy is to perform approximate FHT/TH analysis for given approximation ratio. However, approximate FHT/RT analysis of randomized search heuristics

Fitness levels with tail bounds for the analysis of randomized search heuristics

open access: yesInformation Processing Letters, 2014
The fitness-level method, also called the method of f-based partitions, is an intuitive and widely used technique for the running time analysis of randomized search heuristics.

A fixed budget analysis of randomized search heuristics for the traveling salesperson problem

open access: yesProceedings of the 2014 Annual Conference on Genetic and Evolutionary Computation, 2014
Randomized Search heuristics are frequently applied to NP-hard combinatorial optimization problems. The runtime analysis of randomized search heuristics has contributed tremendously to their theoretical understanding.

Concentrated Hitting Times of Randomized Search Heuristics with Variable Drift

open access: yesLecture Notes in Computer Science, 2014
Drift analysis is one of the state-of-the-art techniques for the runtime analysis of randomized search heuristics (RSHs) such as evolutionary algorithms (EAs), simulated annealing etc.

Optimizing the Classic and the Energy-Efficient Permutation Flowshop Scheduling Problem with a Hybrid Tyrannosaurus Rex Optimization Algorithm [PDF]

open access: yesBiomimetics
This paper introduces a Hybrid Tyrannosaurus Rex Optimization Algorithm (Hybrid TROA) combined with Variable Neighborhood Search (VNS), two variations of the Path Relinking strategy, and a randomized Nawaz–Enscore–Ham (NEH) heuristic to address the ...

Towards a Complexity Theory of Randomized Search Heuristics: Ranking-Based Black-Box Complexity

open access: yesLecture Notes in Computer Science, 2011
Randomized search heuristics are a broadly used class of general-purpose algorithms. Analyzing them via classical methods of theoretical computer science is a growing field.

Approximating Covering Problems by Randomized Search Heuristics Using Multi-Objective Models

open access: yesEvolutionary Computation, 2010
The main aim of randomized search heuristics is to produce good approximations of optimal solutions within a small amount of time. In contrast to numerous experimental results, there are only a few theoretical explorations on this subject.

A randomized heuristics for the mapping problem: The genetic approach

open access: yesParallel Computing, 1992
The combinatorial optimization problem of assigning parallel tasks onto a multiprocessor so as to minimize the execution time is termed as the mapping problem. This problem even in its simplest form is known to be NP-hard.

The Concept of a Novel Path Planning Strategy for Wire + Arc Additive Manufacturing of Bulky Parts: Pixel

open access: yesMetals, 2021
An innovative trajectory strategy was proposed and accessed for wire arc additive manufacturing (WAAM), applicable to different and more complex geometries, rather than being a single solution.

Modeling Multi-Plant Capacitated Lot Sizing Problem with Interplant Transfer [PDF]

open access: yesInternational Journal of Mathematical, Engineering and Management Sciences, 2021
Lot sizing models involve operational and tactical decisions. These decisions may entail multi-level production processes such as assembly operations with multiple plants and limited capacities.
