  • The bi-objective critical node detection problem 
    Ventresca, Mario; Harrison, Kyle Robert; Ombuki-Berman, Beatrice M. (Elsevier, 2018-03)
    Identifying critical nodes in complex networks has become an important task across a variety of application domains. The Critical Node Detection Problem (CNDP) is an optimization problem that aims to minimize pairwise ...
  • Gaussian-valued particle swarm optimization 
    Harrison, Kyle Robert; Ombuki-Berman, Beatrice M.; Engelbrecht, Andries P. (Springer, 2018-10)
    This paper examines the position update equation of the particle swarm optimization (PSO) algorithm, leading to the proposal of a simplified position update based upon a Gaussian distribution. The proposed algorithm, ...
  • Optimal parameter regions and the time-dependence of control parameter values for the particle swarm optimization algorithm 
    Harrison, Kyle Robert; Engelbrecht, Andries P.; Ombuki-Berman, Beatrice M. (Elsevier, 2018-08)
    The particle swarm optimization (PSO) algorithm is a stochastic search technique based on the social dynamics of a flock of birds. It has been established that the performance of the PSO algorithm is sensitive to the values ...
  • 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, ...
