Classification: 11.1.

Nature of problem:
Numerical evaluation of dimensionally regulated Feynman integrals needed in two-loop self-energy calculations in relativistic quantum field theory in four dimensions.

Solution method:
Analytical evaluation in terms of polylogarithms when possible, otherwise through Runge-Kutta solution of differential equations

Restrictions:
Loss of accuracy in some unnatural threshold cases that do not have vanishing masses.

Running time:
Less than a second
