abstract = "The precipitations are characterised by important
spatial and temporal variation. Model determination for
such series is of high importance for hydrological
purposes (e.g. weather forecasting, agriculture, flood
areas, administrative planning), even if discovering
patterns in such series is a very difficult problem.
The objective of the current study is to describe the
use of an adaptive evolutionary technique that give
promising results for the development of non-linear
time series models.",
