Hi,
while iterating through all the polyline's points, only the situation around the current point is evaluated. The algorithm doesn't iterate through the polyline in reverse direction, so possible simplifications aren't found in a single run.
To be sure that all simplifications are found and applied, one has to restart the iteration after each changed point.

Look, if I run about 20 simplification iterations with a tolerance of 1 meter on a polyline, that is about 43km long and has roughly 5k points, then I end up having 14 points with a distance of a couple of kilometers each.
Can this really be correct?

That sounds strange, indeed.
I'll take a closer look and create test cases if I find the time.

@mjaschen, thanks for your awesome work btw!
