Speaking in general terms: no 2 algorithms will give the same answer. Back
in the '60s or early '70s I saw a comparison of algorithms and computers.
The author took 3 equations in 3 unknowns (x, y , and z) and solved them
using different algorithms on the same computer and the same algorithms on
different computers. I dont remember the exact numbers, but some of the
results were off by as much as 50%, some were quite close. The author used
x = y = z = 1
All,
Well that was many years ago. Too assume that today is nonsense. I port
complex numerical algorithms all the tim to/from different algorithms,
programming languagues and platforms. the IEEE standard for floating point
#'s has removed a lot of the ambiguity that used to exist and this is
certainly a non issue today. Those who feel that it is difficult to do are
just ignorant because its quite easy.
