abstract = "This paper presents an experimental research on the
size of individuals when dynamic size populations are
employed with Genetic Programming (GP). By analysing
the individual's size evolution, some ideas are
presented for reducing the length of the best
individual while also improving the quality. This
research has been performed studying both individual's
size and quality of solutions, considering the
fixed-size populations and also dynamic size by means
of the plague operator. We propose an improvement to
the Plague operator, that we have called Random Plague,
that positively affects the quality of solutions and
also influences the individuals' size. The results are
then considered from a quite different point of view,
the presence of processors failures when parallel
execution over distributed computing environments are
employed. We show that results strongly encourage the
use of Parallel GP on non fault-tolerant computing
resources: experiments shows the fault tolerant nature
of Parallel GP.",
