  Loop quantum cosmology leads to a difference equation for the wave function
of a universe, which in general has solutions changing rapidly even when the
volume changes only slightly. For a semiclassical regime such small-scale
oscillations must be suppressed, by choosing the parameters of the solution
appropriately. For anisotropic models this is not possible to do numerically by
trial and error; instead, it is shown here for the Bianchi I LRS model how this
can be done analytically, using generating function techniques. Those
techniques can also be applied to more complicated models, and the results
gained allow conclusions about initial value problems for other systems.
