while space complexity represents the amount of memory space an algorithm requires. Big O notation is a standardized way to express and compare these complexities.

It is amusing that this is kind of a "two-layer" segment tree, and if you change it into three layers, the time complexity handling updates will reduce to M−−√3M3 while not changing the time complexity of queries(since its adds up 33 pieces of information instead of 22). That ...
The boosted regression tree method is a machine learning technique extended from traditional classification and regression trees, which combines the algorithms of regression trees that use recursive binary splits to fit a simple model to each result and boosting that uses an iterative method to ...
[15] to reduce the complexity of the search phase to O(log n + k) at the expense of higher memory requirements. Shen et al. [16] used a lattice decomposition of the span space for a parallel version on a massive parallel machine. View chapterExplore book Collaborative Computing and Appli...
found that the quality of word vectors can be improved with increasing the word range, but the drawback is increased computational complexity. The CBOW model predicts the current word vector from the surrounding words. This architecture is also referred to the bag-of-words model, as the order ...

Thus, the number of pebbles represents the amount of memory necessary to perform some set of computations. The natural complexity measures to optimize in this game is the minimum number of pebbles used, as well as the minimum amount of time it takes to finish pebbling all the nodes; these ...
Using some auxiliary data structures, which are called LCP data structures occupying O(nlogk+1n) bits, this time complexity can be improved to O(p+2hloglogn). Then for every leaf ℓi in the subtree of a locus node, pos(ℓi) represents an occurrence of P in T. Thus...
In this paper, we consider the problem of computing the visibility polygon (VP) of a query point q (or VP(q)) in a scene consisting of some obstacles with total complexity of n. We show that the combinatorial representation of VP(q) can be computed in logarithmic time by preprocessing ...
