Query: Using the quaternion's representation of individuals in swarm
  intelligence and evolutionary computation   This paper introduces a novel idea for representation of individuals using
quaternions in swarm intelligence and evolutionary algorithms. Quaternions are
a number system, which extends complex numbers. They are successfully applied
to problems of theoretical physics and to those areas needing fast rotation
calculations. We propose the application of quaternions in optimization, more
precisely, we have been using quaternions for representation of individuals in
Bat algorithm. The preliminary results of our experiments when optimizing a
test-suite consisting of ten standard functions showed that this new algorithm
significantly improved the results of the original Bat algorithm. Moreover, the
obtained results are comparable with other swarm intelligence and evolutionary
algorithms, like the artificial bees colony, and differential evolution. We
believe that this representation could also be successfully applied to other
swarm intelligence and evolutionary algorithms.
