171 * @defgroup binary_search_algorithms Binary Search
172 * @ingroup sorting_algorithms
173 *
174 * These algorithms are variations of a classic binary search, and
175 * all assume that the sequence being searched is already sorted.
176 *
177 * The number of comparisons will be logarithmic (and as few as
178 * possible). The number of steps through the sequence will be
179 * logarithmic for random-access iterators (e.g., pointers), and
180 * linear otherwise.
181 *
182 * The LWG has passed Defect Report 270, which notes: <em>The
183 * proposed resolution reinterprets binary search. Instead of
184 * thinking about searching for a value in a sorted range, we view
185 * that as an important special case of a more general algorithm:
186 * searching for the partition point in a partitioned range. We
187 * also add a guarantee that the old wording did not: we ensure that
188 * the upper bound is no earlier than the lower bound, that the pair
189 * returned by equal_range is a valid range, and that the first part
190 * of that pair is the lower bound.</em>
191 *
192 * The actual effect of the first sentence is that a comparison
193 * functor passed by the user doesn't necessarily need to induce a
194 * strict weak ordering relation. Rather, it partitions the range.
