A biased random‐key genetic algorithm for the home health care problem

International Transactions in Operational Research, 2022
AbstractHome health care problems consist in scheduling visits to home patients by health professionals while following a series of requirements. This paper studies the Home Health Care Routing and Scheduling Problem, which comprises a multi‐attribute vehicle routing problem with soft time windows.

Steganography using Biased Random Keys Genetic Algorithm

Academic Journal on Computing, Engineering and Applied Mathematics, 2023
A esteganografia é vista com bons olhos no mundo digital como uma alternativa de envio de dados via arquivos em formato digital, mas há questionamentos quanto à sua qualidade e segurança, visto que uma simples degradação a expõe à interceptação de dados.

Detection of network communities with memory-biased random walk algorithms

Journal of Complex Networks, 2016
Community structure and its detection in complex networks has been the subject of many studies in the recent years. Towards this goal, we have created a novel approach based on the analysis of the motion of a memory-biased random walker, i.e. an entity that traverses the network with some tendency to follow or avoid pathways it has previously traversed.

A biased random-key genetic algorithm for the chordal completion problem

RAIRO - Operations Research, 2023
A graph is chordal if all its cycles of length greater than or equal to four contain a chord,i.e., an edge connecting two nonconsecutive vertices of the cycle. Given a graphG= (V, E), the chordal completion problem consists in finding the minimum set of edges to be added toGto obtain a chordal graph.

Biased random-key genetic algorithms: A review

European Journal of Operational Research
This paper is a comprehensive literature review of Biased Random-Key Genetic Algorithms (BRKGA). BRKGA is a metaheuristic that employs random-key-based chromosomes with biased, uniform, and elitist mating strategies in a genetic algorithm framework.

A Weighted and Epsilon-Constraint Biased-Randomized Algorithm for the Biobjective TOP with Prioritized Nodes

Computation
This paper addresses a multiobjective version of the Team Orienteering Problem (TOP). The TOP focuses on selecting a subset of customers for maximum rewards while considering time and fleet size constraints.

Plasma extrachromosomal circular DNA as a biomarker in EGFR‐targeted therapy of non‐small cell lung cancer

Molecular Oncology, EarlyView.
Detection of extrachromosomal circular DNA (eccDNA) in plasma samples from EGFR‐mutated non‐small cell lung cancer patients. Plasma was collected before and during treatment with the EGFR‐tyrosine kinase inhibitor osimertinib. Plasma eccDNA was detected in all cancer samples, and the presence of the EGFR gene on eccDNA serves as a potential biomarker ...
