In all cases the function minimizer just sees an unbound variable x. It
is what haapens to x in between the
function minimizer and the model being parameterized that determines
the boundedness and or scaling.
x ------> a+(b-a)*sin(2*pi*x)
is bounded between a and b from the models point of view
has been scaled by s from the function minimizers point of view
x ------> a+(b-a)*sin(2*pi*x/s)
is bounded from the models point of view and scaled by s from the
function minimizers point of view.
