Integrand-level reduction is a powerful method for loop scattering amplitudes computation. We present an algebraic geometry approach for Integrand-level reduction, which is valid for any renormalizable theories and arbitrary loop orders, in principle. We also show some explicit two-loop and three-loop N=0,1,2,4 (super)-Yang-Mills amplitudes examples, based on our methods.
