Using ASP with recent extensions for causal explanations
We examine the practicality for a user of using Answer Set Programming (ASP)
for representing logical formalisms. We choose as an example a formalism aiming
at capturing causal explanations from causal information. We provide an
implementation, showing the naturalness and relative efficiency of this
translation job. We are interested in the ease for writing an ASP program, in
accordance with the claimed ``declarative'' aspect of ASP. Limitations of the
earlier systems (poor data structure and difficulty in reusing pieces of
programs) made that in practice, the ``declarative aspect'' was more
theoretical than practical. We show how recent improvements in working ASP
systems facilitate a lot the translation, even if a few improvements could
still be useful
