Witryna30 paź 2014 · The basic idea is to find a collection of initial seeds distributed in such a way that you are guaranteed that, for each root, there is at least one of the seeds that converges to that root. This set is quite large but you can quit when you've found all the roots. The multiplicity of the root can be determined by the rate of convergence.
