"NewtonMap-Algebraic" by Huangxin Wang, Univ. of Pennsylvania
"NewtonMap" runs on any color Macintosh. It displays the basins of attraction for the Newton's iterative method for solving the single-complex-variable equation:
z <- z - f(z) / f'(z), in this module, f(z) is an algebraic function.
Since it takes a long time to finish a complete map, it always resumes from where it stops last time. You can delete the "NewtonMap.resume" file to have a fresh start.
You should turn off "SystemIQ" in AfterDark for better speed.
