HashingChainingTime complexityString matching is an integral part of various important areas of computer science viz search engines, DNA matching, information retrieval, security, and biological systems. String matching algorithms are used in finding a pattern in a string. In this paper, the authors ...
<> Advanced data structure What problems can be solved by the time complexity of data structure operation heap (Heap)O(log(n)): push, pop; O(1):top Global dynamic search for maximum and minimum height Hashtable (Hash table)O(1): insert, find, delete Does the query element exist ,key...
Iteration over the long sequencing reads, as opposed to an all-vs-all alignment of reads, allows GoldRush to achieve a linear time complexity in the number of reads. We show that GoldRush produces contiguous and correct genome assemblies with a low memory footprint, and does so without read-...
These costs together have only aminimal influence on Bitcoin's overall value. The complexity of Bitcoin's hashing algorithms and the fact that they can vary wildly in complexity are far more impactful. 3. Competition Bitcoin's cryptocurrency market share has sharply declined over the years. In 2...
Despite DVFS can result in substantial energy savings, the technique has limitations such as difficulty to deal with the complexity of modern CPU architectures (i.e., pipelining, hyperthreading, etc.), which makes nontrivial to determine the required CPU clock frequency to meet application's perfo...
(Bell and Hillmer1984; De Livera et al.2011), etc. To reduce the complexity of time series forecasting and capture these temporal patterns, some models have introduced time series decomposition techniques (Wu et al.2021; Zhou et al.2022; Oreshkin et al.2019; Woo et al.2022). These ...
In the assignment step, the per-cluster scan from SLIC is replaced by the per-pixel update so that invalid depth can be handled while the complexity remains unchanged. We defined two distances between one pixel u\mathbf{u}u and one candidate cluster center Ci{C}_{i}Ci as 在分配步骤...
Out of diff range and nitpick comments (1) sofa-ark-parent/core/common/src/main/java/com/alipay/sofa/ark/common/util/FileUtils.java (1) Line range hint 49-50: Replace SHA-1 with a more secure hashing algorithm. SHA-1 is considered insecure due to its lack of collision resistance. It...
We study the power of preprocessing adversaries in finding bounded-length collisions in the widely used Merkle-Damgård (MD) hashing in the random oracle model. Specifically, we consider adversaries with arbitrary S-bit advice about the random oracle and can make at most T queries to it. Our...
Fine-grained redaction, while enabling the precise modification of individual transactions without affecting others, can lead to scalability and performance issues due to the complexity of its designs and access structures. Security considerations arise concerning the revocation of writing privileges, ...
