  • Robotic architectures 
    Mtshali, Mbali; Engelbrecht, Andries P. (Defence Scientific Information and Documentation, 2010-01)
    In the development of mobile robotic systems, a robotic architecture plays a crucial role in interconnecting all the sub-systems and controlling the system. The design of robotic architectures for mobile autonomous robots ...
  • SAICSIT Papers in the ACM-DL 
    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 ...
  • A scalability study of many-objective optimization algorithms 
    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 ...
  • Seeking multiple solutions : an updated survey on niching methods and their applications 
    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 ...
  • 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 ...
