abstract = "In the present study, gene expression programming
(GEP) technique was used to develop one-month ahead
monthly rainfall forecasting models in two
meteorological stations located at a semi-arid region,
Iran. GEP was trained and tested using total monthly
rainfall (TMR) time series measured at the stations.
Time lagged series of TMR samples having weak
stationary state were used as inputs for the modelling.
Performance of the best evolved models were compared
with those of classic genetic programming (GP) and
autoregressive state-space (ASS) approaches using
coefficient of efficiency (R2) and root mean squared
error measures. The results showed good performance
(0.532 less than 0.56) for GEP models at testing
period. In both stations, the best model evolved by GEP
outperforms the GP and are significantly superior to
the ASS models.",
