  • Self-adaptive differential evolution for dynamic environments with fluctuating numbers of optima 
    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 ...
  • Self-adaptive particle swarm optimization : a review and analysis of convergence 
    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, ...
  • Self-adaptive quantum particle swarm optimization for dynamic environments 
    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 ...
  • Self-perceived intrinsic and extrinsic differences between Information Systems and Computer Science university students 
    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 ...
  • Semi-automated usability analysis through eye tracking 
    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 ...
  • Sensitivity analysis of voronoi-based sensor deployment and reconfiguration algorithms 
    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 ...
  • Set-based particle swarm optimization applied to the multidimensional knapsack problem 
    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 ...
  • “Siel van die mier” : reflections on the battle for ‘scholarly’ intelligence 
    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 ...
