About Automatic Differentiation

+1 vote

Hallo
I have a quite general question about automatic differentiation tools in FFC and UFL. As I could understand from the FEniCS book it is midway between automatic differentiation and symbolic differentiation, and quite close to a forward accumulation mode. I guess if this is correct, and if there is documentation to understand exactly and in detail how this tool works, its performances, and how optimization is performed. I found that in UFL manual that section is missing.

Thank you in advance for any suggestion and sorry if this is not the correct place for such question.

Stefano

Perhaps the UFL paper will provide more insight. See section 6.4.
