Dealing with the complexity of perturbative scattering amplitudes has always been a major challenge when keeping theory uncertainties in line with the experiments. In this talk I will review some techniques that are being used to overcome the current bottlenecks in five-particle two-loop amplitude computations. The use of numerical sampling over finite fields allows us to reconstruct fully analytic information and uncover simple representations for on-shell amplitudes.
