(* "best_slices" must be found empirically, taking a wholistic approach since
the ATPs are run in parallel. Each slice has the format
(time_frac, ((max_facts, fact_filter), format, type_enc,
lam_trans, uncurried_aliases), extra)
where
time_frac = faction of the time available given to the slice (which should
add up to 1.0)
extra = extra information to the prover (e.g., SOS or no SOS).
The last slice should be the most "normal" one, because it will get all the
time available if the other slices fail early and also because it is used if
slicing is disabled (e.g., by the minimizer). *)
