abstract = "Genetic Programming (GP) based modelling is suggested
for modelling the variation of Dissolved Oxygen (DO)
under controlled conditions in the presence and absence
of toxicant. The results indicated that GP is able to
evolve robust physically meaningful models even with
small dataset by selecting the most relevant functions
from the set of functions given for the modelling. It
is interesting to note that the evolved models clearly
reflect the underlying non-linearity of the process
distinctly for both the case studies.",
