In this work we numerically compare the interaction of optical vortices (OVs) in self-defocusing and selffocusing Kerr nonlinear media. We find that the basic scenarios (attraction/repulsion, translation/rotation vs. background) in the interaction of two and three vortices with equal and alternative
