In sum, evolutionary and social algorithms have much in common,
and their fusion seems inevitable. Some evolutionary operations are
markedly analogous to particle swarm methods, but the differences be-
tween approaches are considerable.
Summary
In this book we are looking at a paradigm in its youth, full of potential
and fertile with new ideas and new perspectives. Researchers in many
countries are experimenting with particle swarms, applying their imagi-
nations to this simple system. The algorithm is really just a pair of formu-
las, one for velocity and one for position, a two-line computer program
with some housekeeping (in fact these two lines
