Description
In this talk, using the calculation of the dynamic critical exponent $z$ in the Model A in the four-loop approximation as an example, we will present the diagram reduction technique. This method allows for a substantial decrease in both the number of diagrams and divergent dynamic subgraphs, thereby facilitating subsequent parametric integration with Goncharov polylogarithms.
