| Similar to red-black trees, AVL trees are balanced binary trees. AVL trees |
| are often compared with red-black trees because they support the same set of |
| operations and because both take O(log n) time for basic operations. AVL trees |
| are more rigidly balanced than Red-Black trees, leading to slower insertion |
| and removal but faster retrieval, so AVL trees perform better than red-black |
| trees for lookup-intensive applications. |
| </p> |
| <p> |
| <span class="bold"><strong>Boost.Intrusive</strong></span> offers 3 containers based |
| on avl trees: <code class="computeroutput"><a class="link" href="../boost/intrusive/avl_set.html" title="Class template avl_set">avl_set</a></code>, |
| <code class="computeroutput"><a class="link" href="../boost/intrusive/avl_multiset.html" title="Class template avl_multiset">avl_multiset</a></code> and |
| <code class="computeroutput"><a class="link" href="../boost/intrusive/avltree.html" title="Class template avltree">avltree</a></code>. The first two |
| are similar to <code class="computeroutput"><a class="link" href="../boost/intrusive/set.html" title="Class template set">set</a></code> or <code class="computeroutput"><a class="link" href="../boost/intrusive/multiset.html" title="Class template multiset">multiset</a></code> and the latter is a generalization |
| that offers functions both to insert unique and multiple keys. |
| </p> |
| <p> |
| The memory overhead of these containers with Boost.Intrusive hooks is usually |
| 3 pointers and 2 bits (due to alignment, this usually means 3 pointers plus |
| an integer). This size can be reduced to 3 pointers if pointers have 4 byte |
| alignment (which is usually true in 32 bit systems). |
| </p> |
| <p> |
| An empty, non constant-time size <code class="computeroutput"><a class="link" href="../boost/intrusive/avl_set.html" title="Class template avl_set">avl_set</a></code>, |
| <code class="computeroutput"><a class="link" href="../boost/intrusive/avl_multiset.html" title="Class template avl_multiset">avl_multiset</a></code> or |
| <code class="computeroutput"><a class="link" href="../boost/intrusive/avltree.html" title="Class template avltree">avltree</a></code> also has a size |
| of 3 pointers and an integer (3 pointers when optimized for size). |
