It is well known that the flux creep flow model is effective to explain electric field-current density characteristics of high temperature superconductors. It is necessary to determine the pinning parameters by using flux creep flow model. Therefore, mesh method was used to determine the parameters. In this study, defferential evolution (DE) is used for determination of pinning parameters in flux creep flow model.
