    MicroRNAs (miRNAs) are key gene expression regulators in plants and animals. Therefore, miRNAs are involved in several biological processes, making the study of these molecules one of the most relevant topics of molecular ...
  • Oliveira, Alcione; Miguel, Eliseu; Bigonha, Roberto S.; Bigonha, Mariza A. S.; Di Iorio, Vladimir (Electronic Notes in Theoretical Computer Science, 2005-05-12)
    Artificial intelligence games are a very interesting tool for teaching Artificial Intelligence techniques. Competitors write programs for agents, which are supposed to complete a given task or fight against other agents. ...
  • Santos, Nerilson Terra; Santos, Fábio Lúcio; Queiroz, Daniel Marçal de; Pinto, Francisco de Assis de Carvalho (Acta Scientiarum. Agronomy, 2010-07)
    Harvesting is one of the most important operations in coffee production systems. This operation has a high cost and impact on the final quality of the product. To reduce production costs, producers are looking for ways to ...
  • Arroyo, José Elias C.; Leung, Joseph Y.-T.; Tavares, Ricardo Gonçalves (Engineering Applications of Artificial Intelligence, 2019-01)
    This paper investigates the problem of scheduling a set of jobs with arbitrary sizes and non-zero release times on a set of unrelated parallel batch machines with different capacities so as to minimize the total flow time ...
  • Andrade, Marcus V. A.; Magalhães, Salles V. G.; Magalhães, Mirella A.; Franklin, W. Randolph; Cutler, Barbara M. (GeoInformatica, 2011-04)
    The recent availability of detailed geographic data permits terrain applications to process large areas at high resolution. However the required massive data processing presents significant challenges, demanding algorithms ...
  • Santos, André Gustavo dos; Monaci, Michele (Annals of Operations Research, 2018-12)
    We consider a two-dimensional problem in which one is required to split a given rectangular bin into the smallest number of items. The resulting items must be squares to be packed, without overlapping, into the bin so as ...

  • Iorio, Vladimir O. Di; Reis, Leonardo V. S.; Bigonha, Roberto S.; Amorim, Luis Eduardo S. (Science of Computer Programming, 2014-12-15)
    The term “extensible language” is especially used when a language allows the extension of its own concrete syntax and the definition of the semantics of new constructs. Most popular tools designed for automatic generation ...
  • Rocha, Mauro Nacif; Silva, Soraia Lúcia da; Mateus, Geraldo Robson (Annals of Operations Research, 2002-10)
    The traffic generation models, which describe how the clients use the network services, as well as the mobility models, which describe how clients move within the service area covered by the network, are essential tools ...
  • Arroyo, José Elías Cláudio; Leung, Joseph Y. T. (Computers & Operations Research, 2017-02)
    This research analyzes the problem of scheduling a set of n jobs with arbitrary job sizes and non-zero ready times on a set of m unrelated parallel batch processing machines so as to minimize the makespan. Unrelated parallel ...
  • Ferreira, Ricardo S.; Cardoso, João M. P.; Damiany, Alex; Vendramini, Julio; Teixeira, Tiago (Journal of Systems Architecture, 2011-09)
    Reconfigurable computing architectures are commonly used for accelerating applications and/or for achieving energy savings. However, most reconfigurable computing architectures suffer from computationally demanding placement ...
  • Lelis, Levi H. S.; Stern, Roni; Felner, Ariel; Zilles, Sandra; Holte, Robert C. (Annals of Mathematics and Artificial Intelligence, 2014-10-03)
    Heuristic search algorithms are designed to return an optimal path from a start state to a goal state. They find the optimal solution cost as a side effect. However, there are applications in which all one wants to know ...
  • Lelis, Levi H. S.; Stern, Roni; Arfaee, Shahab Jabbari; Zilles, Sandra; Felner, Ariel; Holte, Robert C. (Artificial Intelligence, 2016-01)
    Optimal planning and heuristic search systems solve state-space search problems by finding a least-cost path from start to goal. As a byproduct of having an optimal path they also determine the optimal solution cost. In ...
  • Souza, Vitor Barbosa C.; Ramirez, Wilson; Marin-Tordera, Eva; Sanchez, Sergio (Optical Switching and Networking, 2017-11)
    The recently coined Internet of Things (IoT) paradigm leverages a large volume of heterogeneous Network Elements (NEs) demanding broad connectivity anywhere, anytime and anyhow, fueling the deployment of innovative Internet ...
