The Software Module Clustering problem seeks to distribute the modules comprising a software system into clusters maximize cluster cohesion and minimize coupling between clusters. Metaheuristics based on local search have been successfully applied find good solutions for this problem, outperforming more-complex, population-based heuristics. In paper, we present heuristic Large Neighborhood Search address problem. We also perform what is our knowledge largest experimental study addressing...
Context: Over the years, tools have been created to improve execution of development process activities. The emergence generative Artificial Intelligence (AI) and, more recently, launch and dissemination Copilot, ChatGPT-3 other tools, broadened discussion about possibility using conversational AI in diverse tasks. Problem: There is still a lack secondary studies map literature how software activities can be affected by usage tools. Solution: This study aims identify which Natural Language...
POPMUSIC—partial optimization metaheuristic under special intensification conditions—is a template for tackling large problem instances. This has been shown to be very efficient various combinatorial problems like p-median, sum of squares clustering, vehicle routing and map labelling. In terms algorithmic complexity, one the most complex part POPMUSIC is find an initial solution. article presents method generating appropriate solution location-routing by producing in O (n3/2) approximate...
Context: The emergence of generative Artificial Intelligence (AI) and, more recently, the dissemination Copilot, ChatGPT-3 and similar tools have broadened discussion about possibility using AI in many professional segments such as health, education, technological area. Problem: Although some studies explore potential to assist Information Technology (IT) professionals executing specific tasks, they do not delve into professionals' characteristics or collect information multiple usage....
As redes sociais se tornaram a principal fonte de informação na era digital. Como consequência, um crescente volume informações vem sendo compartilhado nos ambientes virtuais. Diante desse cenário, há evidências que as estão utilizadas por atores mal-intencionados forma coordenada para manipular outros usuários, o configura como uma ameaça real às democracias. O objetivo deste artigo é apresentar os resultados mapeamento sistemático da literatura sobre uso interferir nas democracias fim...
Critical issues in the Oil & Gas business have been discussed social media, involving policymakers, oil and gas companies, industry individuals, civic activists. As observed recently, such a critical role economic debate political polarization. In this context, paper reports on study for detection of hidden communities influential users networks through analysis Twitter posts during Brazil mega fields auction 2019. We use methodology focused identifying relevant target community discovering...
Software projects usually maintain bug repositories where both developers and end users can report track the resolution of software defects. These defects should be fixed new versions incorporating patches that solve them must released. The project manager schedule a set error correction tasks with different priorities in order to minimize time required accomplish these guarantee more important issues have been fixed. This problem is recurrent for most organizations and, given enormous...
This article addresses a classical problem known for its applicability and complexity: the Bin Packing Problem (BPP). A hybrid grouping genetic algorithm called HGGA-BP is proposed to solve BPP. The inspired by Falkenauer encoding scheme, which applies evolutionary operators at bin level. includes efficient heuristics generate initial population performs mutation crossover groups as well strategies arrangement of objects that were released group operators. effectiveness comparable with best...
Even if a development team uses the best Software Engineering practices to produce high-quality software, end users may find defects that were not previously identified during software life-cycle. These must be fixed and new versions of incorporating patches solve them released. The project manager schedule set error correction tasks with different priorities in order minimize time required accomplish these guarantee more important issues have been fixed. Given large number distinct...
Compara-se o desempenho de duas estratégias balanceamento carga na paralelização da meta-heurística GRASP (Greedy Randomized Adaplive Search Procedure): decomposição pré-escalonada (balanceamento estático) ou auto-escalonada dinâmico) dos dados. As foram testadas sob a influência mesmos fatores externos. O dinâmico revelou-se como melhor alternativa, mostrando significativas melhorias no paralelização.
A interacao com os celulares vem se modificando ao longo do tempo por meio de toques na tela e telefones inteligentes. Diante desse cenario, projetistas encontram barreiras para construirem interfaces que atendam tanto aos usuarios limitacoes quanto comuns. Com o objetivo minimizar esses obstaculos, a presente pesquisa adota uma abordagem avaliacao usabilidade acessibilidade foco terceira idade fim identificar pros contra nos sistemas Android, iOS Windows Phone, bem como propor recomendacoes...
Context: In the last decades, there has been a significant expansion of Internet among world's population and, together with this growth, social network platforms have consolidated as trend and established themselves political environments due to their functionalities, low costs growing number users.
Ceratocone é um problema que provoca alterações no formato e espessura da córnea, deixando-a mais fina menos resistente. Pacientes foram submetidos a cirurgia refrativa laser tem uma chance maior de desenvolver doença pelo afinamento corneano, podendo causar cegueira exigir o transplante córnea. Este artigo apresenta proposta para detectar estágios iniciais ceratocone em pacientes candidatos refrativa, aplicando algoritmos aprendizagem máquina dados oculares biomecânicos córnea forma...
