Can some one point me to a implementation of Quicksort or like algorithms using boost library
std::sort() ?
I think that the algorithm used under std::sort() is implementation detail. The only specification is that it must be O(N log N) in average case. For example, the sorting algorithm used in GNU Standard C++ Library's std::sort() is the introsort algorithm, not quicksort.
In practice that means it's either using quicksort or introsort (until it gets to the leaves, where it might be doing insertion sort). And introsort is just quicksort until it starts to go pathological. So I'd say, apart from it not being in Boost, the answer "std::sort" is a pretty good one. -- Dave Abrahams BoostPro Computing http://www.boostpro.com
