  Interpolated multiple zeta values can be regarded as interpolation
polynomials of multiple zeta values and multiple zeta-star values. In this
paper, we give some algebraic relations of interpolated multiple zeta values,
such as the symmetric sum formula, the shuffle regularized sum formula, a
weighted sum formula and some evaluation formulas with even arguments. All the
algebraic relations provided in this paper are deduced from the extended double
shuffle relations.
