In this paper, we take a step further towards improving the results of [7] and [2]. In particular, using different techniques, we first present two new data structures with complexity 〈(O(n2/logn),O(n)),O(m)〉. Finally, by combining the above techniques we present an improved data...
Time and space complexity are measures used to analyze algorithms' efficiency in terms of resources consumed. Time complexity represents the amount of time an algorithm takes to complete as a function of the input size, while space complexity represents the amount of memory space an algorithm requi...

Given k, for each \(x_i\), we start by computing the k nearest neighbors of \(x_i\) in X using the existing metric \(d_{{\mathcal {A}}}\) of the ambient space. This step has a complexity of \({\mathcal {O}}((k+1) *n^2)\). This set is called the k-nearest ...
0 - This is a modal window. No compatible source was found for this media. Hence, Savitchs theorem states that, for any function,f:N→R+, wheref(n)⩾n NSPACE(f(n)) ⊆ SPACE(f(n)) The following diagram depicts the relationship among different complexity classes. ...
This does not imply that hash trees are always the better choice in practice: It is true for many data structures that better asymptotic efficiency may come at the cost of higher conceptual complexity and therefore lead to poorer performance in practical applications. Sign in to download full-...
The manufacturing process of composite deployable structures has the complexity of multi-physical field coupling, in which the interaction between fibers and matrix has an important impact on the quality and performance of the finished product. This mainly involves the resin flow, crystallization, compac...
Tissues are highly complicated with spatial heterogeneity in gene expression. However, the cutting-edge single-cell RNA-seq technology eliminates the spatial information of individual cells, which contributes to the characterization of cell identities. H
of bioinformatics is as complicated as any other single domain we have encountered. This is at least in part because of its fast-changing nature, the current explosion of genomic and related data, the complexity of the field itself, and the technology backgrounds and attitudes of biologists and...
