Abstract

The ‘bare bones’ (BB) formulation of particle swarm
optimisation (PSO) was originally advanced as a model of
PSO dynamics. The idea was to model the forces between
particles with sampling from a probability distribution in the
hope of understanding swarm behaviour with a conceptually
simpler particle update rule. ‘Bare bones with jumps’ (BBJ)
proposes three significant extensions to the BB algorithm: (i)
two social neighbourhoods, (ii) a tuneable parameter that can
advantageously bring the swarm to the ‘edge of collapse’ and
(iii) a component-by-component probabilistic jump to anywhere
in the search space. The purpose of this paper is to investigate
the role of jumping within a specific BBJ algorithm, cognitive
BBJ (cBBJ). After confirming the effectiveness of cBBJ, this
paper finds that: jumping in one component only is optimal
over the 30 dimensional benchmarks of this study; that a small
per particle jump probability of 1/30 works well for these
benchmarks; jumps are chiefly beneficial during the early stages
of optimisation and finally this work supplies evidence that
jumping provides escape from regions surrounding sub-optimal
minima.
