• Modified gravity
• Agegraphic dark energy model
• Gauss-Bonnet gravity
• Reconstruction

The cosmological reconstruction of modified F(R) and F(G) gravities with agegraphic dark energy (ADE) model in a spatially flat universe without matter field is investigated by using e-folding "N" as a forward way. After calculating a consistent F(R) in ADE's framework, we obtain conditions for effective equation of state parameter w(eff), and see that reconstruction is possible for both phantom and non-phantom era. These calculations also are done for F(G) gravity and the condition for a consistent reconstruction is obtained.
