+# The general idea would be to form a residual term that is squared reactivity
+# differences between detailed transport (e.g. Serpent) and Moltres' results.
+# A Jacobian is formed from perturbing each rod multiplicative factor. Then
+# a Newton iteration is done to drive the residual to zero. Repeat until results
+# are within uncertainty of the Monte Carlo neutronics. Note that forming the Jacobian
+# for this residual should probably happen in parallel on a computing cluster.
