Abstract

In this study, we have put the mechanism for a Friedmann equation of modified f(G) gravity by solving it with numerical method in the view of matter with pressure-less condition. This mechanism allows us to forecast the redshift action of expansion rate of the Hubble. Here, in this paper, we have applied a Bayesian Markov Chain Monte Carlo (MCMC) technique, which is applying late time cosmic observances to put limitation on the model parameters of the Gauss Bonnet . Our understanding results in the fact that the $f(G)$ model can restore low redshift action of the standard ($\Lambda$ CDM) model. We have used Hubble (OHD), Pantheon and RSD for MCMC analysis of the logarithmic model of $f(G)$ and to constrain parameters including \(\Omega_m\) and \(H_{0}\).
