In order to obtain general results, we use two model-independent approaches. The first reconstructs the EoS using comoving distance and the second makes use of the Hubble parameter data. To implement the first method, we use a recent set of Gamma-Ray Bursts (GRBs) measures. To implement the second method, we generate simulated data using the Sandage-Loeb ($SL$) effect; for the fiducial model, we use the $\\Lambda CDM$ model. In both cases, the statistical analysis is conducted through the Ga","authors_text":"A. M. Velasquez-Toribio, Julio C. Fabris, M. M.
