abstract = "Although many real world problems are dynamic in
nature, the study of Genetic Programming in dynamic
environments is still immature. This paper investigates
the application of some recently proposed
semantic-based crossover operators on a series of
dynamic problems. The operators studied include
Semantic Similarity based Crossover and the Most
Semantic Similarity based Crossover. The experimental
results show the advantage of using semantic-based
crossovers when tackling dynamic problems.",
