Cosmographic Parameters in Model-independent Approaches

Cosmographic approach, a Taylor expansion of the Hubble function, has been used as model-independent method to investigate evolution universe in presence cosmological data. Apart from possible technical problems like radius convergence, there is an ongoing debates about tensions appear when one investigates some high redshift In this work, we consider two common data sets namely SNIa (Pantheon sample) and advantages disadvantages cosmographic approach. To do this, obtain functions using well other known approaches namely, Gaussian process Genetic algorithm. We also assume $\Lambda$CDM model concordance compare results mentioned approaches. Our indicate that cosmography comparing with approaches, are not exact enough. Considering which less certain, $q_0$ $j_0$ obtained cosmography, provides tension at more than $3\sigma$ away best result $\Lambda$CDM. Assuming both samples different show because providing biased results, approach for reconstruction functions, especially higher redshifts.
