The influence of nonequilibrium initial values of the order parameter on its evolution at a critical point is described using a renormalization group approach of the field theory. The dynamic critical exponent {theta} of the short time evolution of a system with an n-component order parameter is calculated within a dynamical dissipative model using the method of {sigma}-expansion in a three-loop approximation. Numerical values of {theta} for three-dimensional systems are determined using the Pade-Borel method for the summation of asymptotic series.
