  In this presentation we review the current status in the automated evaluation
of scattering amplitudes, with particular attention to the developments related
with NLO calculations, which led to the construction of powerful multi-purpose
computational tools. After a general overview, we will devote a short section
to describe the GoSam framework for NLO calculations and its application to the
production of Higgs boson plus jets. We will then briefly comment on the
challenges presented by NNLO calculations, whose structure is considerably more
complicated. Finally, we will describe some of the features of the
integrand-reduction techniques beyond NLO, an alternative promising approach to
multi-loop calculations which is currently under development.
