Issue #20 new

Martin Sandve Alnæs created an issue 2013-06-17

Implementing reverse mode AD might improve derivative computations, but this does not seem likely. Reconsider if examples of slow jacobis are found after upcoming uflacs based form compilation has matured.

Implementing the differentiation algorithm by converting to a list based graph representation first, applying AD on that representation, and converting back, could give a significant speedup because today many nodes are visited more than once.
