-/**
- * \brief Find a suitable subrange of candidate duplicates for a given state
- * \param list dynamic array of states/pairs with candidate duplicates of the current state;
- * \param ref current state/pair;
- * \param min (output) index of the beginning of the the subrange
- * \param max (output) index of the enf of the subrange
- *
- * Given a suitably ordered array of states/pairs, this function extracts a subrange
- * (with index *min <= i <= *max) with candidate duplicates of the given state/pair.
- * This function uses only fast discriminating criterions and does not use the
- * full state/pair comparison algorithms.
- *
- * The states/pairs in list MUST be ordered using a (given) weak order
- * (based on nb_processes and heap_bytes_used).
- * The subrange is the subrange of "equivalence" of the given state/pair.
