Summary: Newton’s iteration is a classical numerical method to find a zero of a system of nonlinear equations. In this paper we discuss recent advances in this subject: homogeneous and multihomogeneous systems, overdetermined and underdetermined systems are considered. We also discuss some complexity aspects of continuation methods using Newton’s method.
