From a user perspective an augmented array based B+ tree of the new

Hi all, In response to the previously made suggestion, I have added to the documentation the comparison of new proposed STL containers with Boost.Container. Please let me know if some of my statements concerning Boost.Container are incorrect, I will update the documentation. library can be regarded as a segmented vector that offers several more efficient operations than std::vector: logarithmic time insertion, erasure, splice and split. One such data structure can support interfaces of all C++03 standard sequences and associative containers. This is why new containers offer a higher level of uniformity and generalization of the C++ standard containers. Unlike std::vector, the new array based containers do not have the problem of exponential storage growth and manual shrinking storage to the optimal capacity. The comparison section also includes simple tests of performance. One test shows the advantage of the wide set of efficient operations of new containers. None of the C++ standard and Boost containers can outperform new containers in the test with just two operations: move an iterator to a specified position and then insert a new element. The other test shows that new containers have good locality of reference. In sequential processing they perform much better than containers using dynamically allocated data structures. String algorithms The new sequence container that implements the union of interfaces of std::vector, std::list and std::deque is particularly beneficial for string algorithms. A container, such as std_ext_adv::sequence<char>, efficiently supports all main editing string operations: cut, copy, paste, delete, find, replace, etc. In terms of computational complexity this new container provides general and equally efficient support for both copy and move semantics operations. The move semantics functions splice() and split() can be used to replace inefficient copy semantics functions insert() and erase() to achieve significant performance improvements. The examples section and code shows how to concatenate two strings and extract a sub-string in logarithmic time using the move semantics functions. These operations do not require that user algorithms count moved characters. This functionality and efficiency are not possible with linked lists and basic search trees. The efficient calculation of statistical parameters and numerical integration in logarithmic time are the other practically important applications of the new containers. They are discussed in the examples section.
