Abstract
We present an approach to compute two-loop amplitudes combining Feynman diagram input, numerical sampling over finite fields and functional reconstruction techniques. We apply the method to compute numerically W+4 parton scattering amplitudes and to derive analytical form of four-quark one-gluon amplitudes, both in the leading colour approximations.
