I'm aware of the Rosenfeld-Gröbner algorithm "for computing a regular decomposition of a radical differential ideal generated by a set of polynomial differential equations, ordinary or with partial derivatives" as it's described in [1].

Is this the best known generalization of Buchberger's algorithm to differential algebra?

Leaving any specific algorithm aside, is the representation of the ideal produced by Rosenfeld-Gröbner the best known generalization of Gröbner bases to differential algebra?
