abstract = "A new model of Genetic Programming with variable size
population is presented in this paper and applied to
the reconstruction of target functions in dynamic
environments (i.e. problems where target functions
change with time). The suitability of this model is
tested on a set of benchmarks based on some well known
symbolic regression problems. Experimental results
confirm that our variable size population model finds
solutions of similar quality to the ones found by
standard Genetic Programming, but with a smaller amount
of computational effort.",
