 Would it be better to pass the functor f by ref for the following

 template <class F, class T>
 std::pair<T, T> brent_find_minima(F f, T min, T max, int bits);

 template <class F, class T>
 std::pair<T, T> brent_find_minima(F f, T min, T max, int bits,
 boost::uintmax_t& max_iter);

 To instead be:

 template <class F, class T>
 std::pair<T, T> brent_find_minima(F& f, T min, T max, int bits);

 template <class F, class T>
 std::pair<T, T> brent_find_minima(F& f, T min, T max, int bits,
 boost::uintmax_t& max_iter);
