Choosing the size of
chooses
the stiffness of the curve that connects regions of good data.
Our first test cases gave solutions
we interpreted to be
too stiff at early times and too flexible at later times,
which suggests we weaken
at early times and strengthen it later.
Because we wanted to keep
constant with time,
we strengthened
at early times
and weakened it at later times
as you see in the following program:
