Each solution variable starts at its guessed value if
there is one; otherwise, it starts at 0.0.
Use guesses to seek additional solutions one by
one. For convergence, a guess may have to be
rather close to a solution.

SortA
Sorts the elements of the first argument in
ascending order.
If you include additional arguments, sorts the
elements of each so that their new positions match
the new positions of the elements in the first
argument.
All arguments must be names of lists or vectors. All
arguments must have equal dimensions.
