Abstract
The down-hill method by Ward is a numerical method for determining a complex root of ƒ(
z
) = 0 and suitable for machine computation [1]. It is based on a theorem that
W
(
z
) = |Re(ƒ)| + |Im(ƒ)| (1) has minimum value, actually zero, at and only at a root of ƒ and seeks to minimize
W
by non-random walk from a starting point over the complex plane.
