Abstract: Anderson localization is a universal phenomenon preventing transport in disordered linear media. I discuss how nonlinearity affects the localization, via numerical studies of different setups: by following spreading of an initially bounded wave packet, and determining transparency of a finite disordered layer. I discuss difficulties in finding an asymptotic regime, and describe scaling approaches aimed at understanding it.
