  • Gruner, Stefan (Computer Society of South Africa, 2019-12)
    On the 5th of October 2019 I browsed the ACM-DL's database with the search key 'South Africa' in the 'conference location' field such as to obtain all ACM-DL-listed conference papers which were at any time presented in ...
  • Maltese, Justin; Ombuki-Berman, Beatrice M.; Engelbrecht, Andries P. (Institute of Electrical and Electronics Engineers, 2018-02)
    Over the past few decades, a plethora of computational intelligence algorithms designed to solve multiobjective problems have been proposed in the literature. Unfortunately, it has been shown that a large majority of these ...
  • Li, Xiaodong; Epitropakis, Michael G.; Deb, Kalyanmoy; Engelbrecht, Andries P. (Institute of Electrical and Electronics Engineers, 2017-08)
    Multimodal optimization (MMO) aiming to locate multiple optimal (or near-optimal) solutions in a single simulation run has practical relevance to problem solving across many fields. Population-based meta-heuristics have ...
  • Du Plessis, M.C. (Mathys Cornelius); Engelbrecht, Andries P. (Springer, 2013)
    Despite the fact that evolutionary algorithms often solve static problems successfully, dynamic optimization problems tend to pose a challenge to evolutionary algorithms [21]. Differential evolution (DE) is one of the ...
  • Harrison, Kyle Robert; Engelbrecht, Andries P.; Ombuki-Berman, Beatrice M. (Springer, 2018-09)
    Particle swarm optimization (PSO) is a population-based, stochastic search algorithm inspired by the flocking behaviour of birds. The PSO algorithm has been shown to be rather sensitive to its control parameters, and thus, ...
  • Pamparà, Gary; Engelbrecht, Andries P. (Springer, 2018-10)
    The quantum-inspired particle swarm optimization (QPSO) algorithm has been developed to find and track an optimum for dynamic optimization problems. Though QPSO has been shown to be effective, despite its simplicity, it ...
  • Alexander, Patricia Margaret; Lotriet, H.H. (Hugo H.); Pieterse, H.V. (Computer Society of South Africa, 2014-07)
    Strong arguments exist that the sub-disciplines of Information Systems (IS) and Computer Science (CS) can be meaningfully distinguished, and the literature indicates that teams in which there are variety of personalities ...
  • Malan, Katherine M.; Eloff, Jan H.P.; De Bruin, J.A. (Jhani) (Computer Society of South Africa, 2018-07-10)
    Usability of software is a crucial aspect of successful applications and could give one application a competitive edge over another. Eye tracking is a popular approach to usability evaluation, but is time consuming and ...
  • Nicholls, Gareth; Kourie, Derrick G.; Strauss, Tinus (Computer Society of South Africa, 2009-07)
    This study examines the effects of location inaccuracies on two movement-assisted Voronoi-based sensor deployment and reconfiguration algorithms, VEC and VOR, due to Wang et al. For the purposes of examining the extent ...
  • Langeveld, Joost; Engelbrecht, Andries P. (Springer, 2012-11-29)
    Particle swarm optimization algorithms have been successfully applied to discrete- valued optimization problems. However, in many cases the algorithms have been tailored specifically for the problem at hand. This paper ...
  • Olivier, Martin S. (Vaal Triangle Faculty of Northwest University in South Africa, 2015-11)
    This essay traces two research programmes in broad strokes. Both programmes start from the same observation — the behaviour of an ant (or termite) colony and the ability of the ant colony to act in a collective manner ...
  • Mohiuddin, Mohammad A.; Khan, Salman Ahmad; Engelbrecht, Andries P. (Springer, 2014-09)
    Optimal utilization of resources in present- day communication networks is a challenging task. Rout- ing plays an important role in achieving optimal re- source utilization. The open shortest path rst (OSPF) routing ...
  • Pieterse, Heloise; Olivier, Martin S.; Van Heerden, Renier (Elsevier, 2018-03)
    Ever improving smartphone technology, along with the widespread use of the devices to accomplish daily tasks, leads to the collection of rich sources of smartphone data. Smartphone data are, however, susceptible to change ...
  • Lo, Johnny Li-Chang; Bishop, Judith; Eloff, Jan H.P. (Elsevier, 2008-10)
    Short Message Service is usually used to transport unclassified information, but with the rise of mobile commerce it has become an integral tool for conducting business. However, SMS does not guarantee confidentiality and ...
  • Mouton, Francois; Leenen, Louise; Venter, H.S. (Hein) (Elsevier, 2016-06)
    The field of information security is a fast-growing discipline. Even though the effectiveness of security measures to protect sensitive information is increasing, people remain susceptible to manipulation and thus the ...
  • Gruner, Stefan (Computer Society of South Africa, 2011-07)
    Small software companies make for the majority of software companies around the world, but their software development processes are often not as clearly de ned and structured as in their larger counterparts. Especially the ...
  • Kourie, Derrick G. (Royal Society of South Africa, 2010-06)
    The South African Computer Journal (SACJ), as the successor of the Quæstiones Informaticæ journal founded by Derek Henderson, is part of his heritage to South Africa. This brief historical sketch of SACJ outlines the ...
  • Cleghorn, Christopher Wesley; Scheepers, Christiaan; Engelbrecht, Andries P. (Springer, 2018-10)
    At present particle swarm optimizers (PSO) designed for multi-objective optimization have undergone no form of theoretical stability analysis. This paper derives the sufficient and necessary conditions for order-1 and ...
  • Malan, Katherine Mary; Engelbrecht, Andries P. (Elsevier, 2013-08)
    Real-world optimisation problems are often very complex. Metaheuristics have been successful in solving many of these problems, but the difficulty in choosing the best approach can be a huge challenge for practitioners. ...
  • Karie, Nickson M.; Venter, Hein S. (Wiley, 2015-07)
    Since its inception, over a decade ago, the field of digital forensics has faced numerous challenges. Despite different researchers and digital forensic practitioners having studied and analysed various known digital ...
