Optimal and nearly optimal algorithms for approximating polynomial zeros
The author presents a new algorithm for approximating all complex zeros of a polynomial. The new algorithm is shown to be superior to the previous best algorithms -- in fact it is shown to be asymptotically optimal. Parallel aspects are also addressed and, even though no results on a parallel implementation are reported, the algorithm is expected to parallelize well.
