  The crystalline structure of ground-state orthorhombic SrRuO$_3$ is
reproduced by applying hybrid density functional theory scheme to the
functionals based on the revised generalized-gradient approximations for
solid-state calculations. The amount of Hartree-Fock (HF) exchange energy is
varied in the range of $5-20\%$ in order to systematically ascertain the
optimum value of HF mixing which in turn ensures the best correspondence to the
experimental measurements. Such investigation allows to expand the set of tools
that could be used for the efficient theoretical modelling of, for example,
only recently stabilized phases of SrRuO$_3$.
