.. class:: traversal_bfs_exp_m

    Tree traversal visitor for breadth-first traversal with experimental paths,
    with fallback to depth-first traversal at a given memory limit.

    The class is DefaultConstructible.

    .. function:: traversal_bfs_exp_m(const std::size_t max_mem_mb)

        Construct with a given memory limit, in multiples of :math:`1024*1024` bytes.
        Note that memory usage is calculated conservatively and the algorithm uses slightly more meory.
        Memory usage by individual visitors is not factored in at this time.
