Late time acceleration in f(G) model

Late time transition is obtained with a function of Gauss Bonnet curvature $f(G)$ in the Einstein Hilbert action with a matter field in a FLRW spacetime assuming an ansatz without a specific $f(G)$ . Late time accelerating expansion is either a phantom era without Big Rip singularity or a quintessence era or a de-Sitter era of expansion. The equation of state parameter, jerk and snap parameters support observational data and the function $f(G)$ obtained from the solution supports earlier works.
