Java Runtime Performance Vs Native C / C++ Code? http://stackoverflow.com/questions/1984856/java-runtime-performance-vs-native-c-c-code faster shared ownership can be handled with negligible amortized cost where in a native language you'd have to use reference..
Is there any advantage of using map over unordered_map in case of trivial keys? http://stackoverflow.com/questions/2196995/is-there-any-advantage-of-using-map-over-unordered-map-in-case-of-trivial-keys I used map before because of the efficiency of lookup amortized O 1 vs. O log n . Most times I use a map I use either int 's..

The amortized complexity of std::next_permutation? http://stackoverflow.com/questions/4973077/the-amortized-complexity-of-stdnext-permutation amortized complexity of std next_permutation I just read this other question.. response O n it seems like the algorithm might have a nice amortized analysis that shows a lower complexity. Does anyone know of.. assuming the elements are distinct looks like it is O 1 amortized Of course there might be errors in the below Let us count the..
When do you prefer using std::list<T> instead of std::vector<T>? http://stackoverflow.com/questions/5056973/when-do-you-prefer-using-stdlistt-instead-of-stdvectort supports random access iterators. In addition it supports amortized constant time insert and erase operations at the end insert..

What.. time requirement for the push_back operation. What amortized constant time means and how exponential growth achieves this.. the capacity by an exponential factor you end up with an amortized constant cost. This probably seems a bit odd so let me explain..
What really is a deque in STL? http://stackoverflow.com/questions/6292332/what-really-is-a-deque-in-stl mentioned that reallocation may happen and that O 1 is an amortized cost like for a vector . So I wonder what is this structure..
