Calculating complexity of algorithm

I am not sure if this is a valid question. Let\'s assume there is an O(n^3) algorithm which sorts 100 numbers per day with a computing power x.[详细]

Does binary search have logarithmic performance of deque C++ data structure?

The standard says that std::binary_search(...) and the two related functions std::lower_bound(...)开发者_高级运维 and std::upper_bound(...) are O(log n) if the data structure has random access. So, gi[详细]

Is log(n) = Ω(n)?

I believe it\'s not. The definition is that: log(n) >= c*n for some n = x, and all n > x The reason I think it\'s not is th开发者_运维百科at the rate of growth of c*n = c. The rate of growth[详细]

Sorting algorithms for data of known statistical distribution?

It just occurred to me, if you know something about the distribution (in the statistical sense) of the data to sort, the performance of a sorting algorithm might benefit if you take that information i[详细]
