Symbolic backwards execution (SBE) is a useful variation on standard forward symbolic evaluation; it allows a symbolic evaluation to start anywhere in the program and proceed by executing in reverse to the program start. SBE brings goal-directed reasoning to symbolic evaluation and has proven effective in e.g. automated test generation for imperative languages.

In this paper we define DDSE, a novel SBE which operates on a functional as opposed to imperative language; furthermore, it is defined as a natural extension of a backwards-executing interpreter. We establish the soundness of DDSE and define a test generation algorithm for this toy language. We report on an initial reference implementation to confirm the correctness of the principles.
