* ALG_SHAVING_CHANGE_NB: the number of successes when attempting to shave a value
* ALG_SHAVING_NO_CHANGE_NB: the number of failures when attempting to shave a value
* PROPAGATOR_ENTAILMENT_NB: the number of calls to a propagator's :code:`compute_domains` method resulting in an entailment
* PROPAGATOR_FILTER_NB: the number of calls to a propagator's :code:`compute_domains` method
* PROPAGATOR_FILTER_NO_CHANGE_NB: the number of calls to a propagator's :code:`compute_domains` method resulting in no domain change
* PROPAGATOR_INCONSISTENCY_NB: the number of calls to a propagator's :code:`compute_domains` method resulting in an inconsistency
* SOLVER_BACKTRACK_NB: the number of calls to the solver's :code:`backtrack` method
