The reduction is essentially based on a particular implementation of the Gauss elimination algorithm which is applied to a system of equation obtained from the original Feynman diagrams. The main problem in the practical implementation of the Laporta-algorithm is that the number of equations ranges typically up to several millions and thus an effective method is mandatory.
