In this project, a big number of mid-transit times from ExoClock and TESS projects are employed to investigate the possible non-linear transit timing variations of exoplanets by performing data-model fitting with both the fixed orbit and the orbital variation models. Sixty-five exoplanets are classified into three types and several exoplanets in favor of orbital variations are found. Their tidally evolutionary orbits are also studied and presented.
