128 * @defgroup algorithms Algorithms
130 * Components for performing algorithmic operations. Includes
131 * non-modifying sequence, modifying (mutating) sequence, sorting,
132 * searching, merge, partition, heap, set, minima, maxima, and
133 * permutation operations.
137 * @defgroup mutating_algorithms Mutating
138 * @ingroup algorithms
142 * @defgroup non_mutating_algorithms Non-Mutating
143 * @ingroup algorithms
147 * @defgroup sorting_algorithms Sorting
148 * @ingroup algorithms
152 * @defgroup set_algorithms Set Operation
153 * @ingroup sorting_algorithms
155 * These algorithms are common set operations performed on sequences
156 * that are already sorted. The number of comparisons will be
157 * linear.
161 * @defgroup binary_search_algorithms Binary Search
162 * @ingroup sorting_algorithms
164 * These algorithms are variations of a classic binary search, and
165 * all assume that the sequence being searched is already sorted.
167 * The number of comparisons will be logarithmic (and as few as
168 * possible). The number of steps through the sequence will be
169 * logarithmic for random-access iterators (e.g., pointers), and
170 * linear otherwise.
172 * The LWG has passed Defect Report 270, which notes: <em>The
173 * proposed resolution reinterprets binary search. Instead of
174 * thinking about searching for a value in a sorted range, we view
175 * that as an important special case of a more general algorithm:
176 * searching for the partition point in a partitioned range. We
177 * also add a guarantee that the old wording did not: we ensure that
178 * the upper bound is no earlier than the lower bound, that the pair
179 * returned by equal_range is a valid range, and that the first part
180 * of that pair is the lower bound.</em>
182 * The actual effect of the first sentence is that a comparison
183 * functor passed by the user doesn't necessarily need to induce a
184 * strict weak ordering relation. Rather, it partitions the range.
