166 * @defgroup binary_search_algorithms Binary Search
167 * @ingroup sorting_algorithms
168 *
169 * These algorithms are variations of a classic binary search, and
170 * all assume that the sequence being searched is already sorted.
171 *
172 * The number of comparisons will be logarithmic (and as few as
173 * possible). The number of steps through the sequence will be
174 * logarithmic for random-access iterators (e.g., pointers), and
175 * linear otherwise.
176 *
177 * The LWG has passed Defect Report 270, which notes: <em>The
178 * proposed resolution reinterprets binary search. Instead of
179 * thinking about searching for a value in a sorted range, we view
180 * that as an important special case of a more general algorithm:
181 * searching for the partition point in a partitioned range. We
182 * also add a guarantee that the old wording did not: we ensure that
183 * the upper bound is no earlier than the lower bound, that the pair
184 * returned by equal_range is a valid range, and that the first part
185 * of that pair is the lower bound.</em>
186 *
187 * The actual effect of the first sentence is that a comparison
188 * functor passed by the user doesn't necessarily need to induce a
189 * strict weak ordering relation. Rather, it partitions the range.
