Description

The rapid progression of analytic evaluation techniques for Feynman integrals in the recent years has been substantially driven by novel insights into the underlying mathematical structures. I will show how some of these structures can be used to accelerate numerical Feynman integral calculations. As a concrete example, I will introduce a Monte-Carlo integration algorithm of Feynman parametric integrals whose runtime only scales polynomially in the number of edges of the underlying graph.
