We review recent progress on computing scattering amplitudes of planar = 4 super Yang‐Mills at strong coupling by using the AdS/CFT duality. The problem boils down to the computation of certain minimal areas on AdS. We show how to use the integrability of the classical equations of motion in order to efficiently compute such minimal areas.
