      An algorithm is proposed for the EOS parameter recovery using data of experiments, which is based on minimizing the multidimensional nonlinear functional with limitations.
      The equation of state is constructed, which takes into account the thermal oscillation of atoms and thermal excitation of electrons, uses the cubic online-approximation of elastic pressure and Grueneisen factor, and provides continuity of thermodynamic quantities up to and including the second derivatives. The numerical results obtained for iron are compared with data of experiments.
