). The reason
is that the hard constraints imposed by optimization_constraint
may make it more difficult for the optimizer to converge.

quantity
-- The quantity to be constrained, given as an
rpn expression in terms of the optimization variables, the
optimization covariables, and and the ``final'' parameters (see the
entry for run_setup
for the last of these). The optimization
(co)variables are referred to as
<element-name>.<parameter-name>
, in all capital letters.
lower
, upper
-- The lower and upper limits
allowed for the expression.
