✦ Synopsis

What is the most efficient algorithm evaluating Feynman diagrams on the lattice? We address the question, and suggest an answer that employs fast Fourier transforms where possible, while avoiding excessive memory requirements.

Present and future high-precision tests of the Standard Model and beyond for the fundamental constituents and interactions in Nature are demanding complex perturbative calculations involving multi-leg and multi-loop Feynman diagrams. Currently, large e ort is devoted to the search for closed express
