Title: Finding master integrals of uniform weight

Abstract:
Finding master integrals of uniform weight is an essential step in computing Feynman integrals. It is well-known that constant leading singularities and maximal cuts provide helpful information for this task. Based on these concepts I describe a heuristic method, which turns this problem for non-trivial situations into an back-of-the-envelope calculation. I illustrate the method with a two-loop penguin diagram.
