Reconstruction of f(R) gravity models from observations.
We investigate the method for the reconstruction of f(R) gravity models both from the background evolution observations and from the large scale structure measurements. Due to the lack of the first principles, one needs to rely on the observations to build the $f(R)$ gravity models. We show that the general $f(R)$ models can be specified if the 5\% accuracy level large scale structure formation observations will be available in the near future.
