This happens often, even when there is a significant difference in time complexity, such as O(N) and O(N^2). If you want to know where the time complexity of hashmap, especially the unordered_map of C++, has a big constant, check the following videos and links....

DirectX 11引进了一种缓存类型,允许访问任一位置像素的值,该功能叫做UAV(unordered access view)。这个功能一开始只有像素着色器和compute shader可以用,到DirectX 11.1这里,所有的着色器都可以使用UAV功能。Opengl 4.3称这个功能为SSBO(shader storage buffer object)。两个名字都用他们自己的方式解释了这个功能。像素着...

Since decoding complexity is proportional to the number of trellis states and branches, this tends to become excessively computationally expensive. 3.4.2 STBC Space-time block codes, as the name suggests, are block rather than trellis-based. In their best known form they avoid the complexity ...

4.2. Computational complexity We compare the standard power iteration eigenvector computation with our filtering formulation, both from qualitative and quantitative points of view. In terms of the quantitative comparative analysis, we will look at both accuracy (how close the filtering is to the exact...
I thought my solution worked in O(n) but it clearly either doesn't or something else is very wrong. My thought process was that both makeWanted and dfs should work in O(n) since there are no loops in a tree, so solve() should be O(n) as well. ...
