  In this presentation, we review the general features of integrand-reduction
techniques, with a particular focus on their generalization beyond one loop. We
start with a brief discussion of the one-loop scenario, a case in which
integrand-reduction algorithms are well established and played over the past
decade an important role in the development of automated tools for the
theoretical evaluation of physical observables. The generalization of
integrand-reduction techniques to all loops has been the subject of several
efforts in the recent past, thus providing a better understanding of the
universal properties of scattering amplitudes. The ultimate goal of these
studies is the development of efficient alternative computational techniques
for the evaluation of Feynman integrals beyond one loop.
