If you want to implement optimization in a curved space with a
non-Euclidean metric (say in the space of correlation matrices or
SO(3)), you usually can't just use numpy arrays in the optimization
implementations that we have. You really do need to rewrite the
algorithm in terms of the abstract operations. For example,
"I have come to believe that the whole world is an enigma, a harmless
enigma that is made terrible by our own mad attempt to interpret it as
though it had an underlying truth."
-- Umberto Eco
