Cosmic accelerating expansion; modified gravity; energy condition
The f(G) gravity is a theory to modify the general relativity and it can explain the present cosmic accelerating expansion without the need of dark energy. In this paper the f(G) gravity is tested with the energy conditions. Finally, we examine two concrete examples with WEC and obtain the allowed region of model parameters.
