Hi,

I have a numerical algorithm for auto-differentiation of higher order
derivatives. The algorithm works fine, and I want to optimize it now.

Is there a direct way to transform an expression tree into another one?
For example, is it possible that every proto::plus< > node is
transformed to it left child? I tried to solve this problem via protos
build-in transforms without success. It seems that they are suited for
evaluation of an existing tree, but I might be wrong.

Best regards,

Karsten
