abstract = "Grammatical Evolution (GE) is a grammar-based form of
Genetic Programming. One important operator in GE
algorithms is the selection scheme. The objective of
this study is a comparison of two models of survivor
selection, the generational replacement and steady
state, for use in tidal level forecasting. The survivor
selection schemes are compared and evaluated according
to their properties. The results show the performance
of steady state is 95.66percent and 94.39percent for
generalation replacement.",
