39.2.2 A Work-Efficient Parallel ScanOur implementation of scan from Section 39.2.1 would probably perform very badly on large arrays due to its work-inefficiency. We would like to find an algorithm that would approach the efficiency of the sequential algorithm, while still taking advantage of ...
The first published() implementation of scan on the GPU was that of Sengupta et al. (2006), also used for stream compaction. They showed that a hybrid work-efficient (() operations with 2steps) and step-efficient ((log) operations withsteps) implementation had the best performance on...
1. Problem Statement given two arrays and a target value, we need to find the pair value that their sum is most closest to the target value. 2. Analysis solution 1, brute force check every pair and compare the sum with the target value.(time: O(n^2)) solution 2, traverse one array...
A better solution is using two pointers instead of one. This makes time complexity of O(n^2). To avoid duplicate, we can take advantage of sorted arrays, i.e., move pointers by >1 to use same element only once. 1:publicArrayList<ArrayList<Integer>> threeSum(int[] num) { 2: ArrayL...
Analysis Time Complexity: O(n²) due to the two nested loops iterating through the array. Space Complexity: O(1) as no additional space is used beyond the input array. Approach 2: Using Sliding Window The sliding window approach is efficient for arrays containing only positive numbers. ...
Hon et al. consider the Dynamic version of the Searchable Partial Sum problem [16]. Another generalization is to use multidimensional arrays and this variant has been studied by the data base community [4,12,13,15,24,25]. Several lower bounds have been presented for the Prefix Sum problem:...
In CR networks which was first introduced by [1], secondary users (SU) get permission to use the licensed spectrum till the induced interferences on the primary receivers kept below the predefined threshold [2,3]. Due to spatial filtering, deploying arrays in underlay CR has been considered ...
21 Compared with the conventional NOMA, the transmit/receive beamforming with large phased arrays for millimeter-Wave (mmWave) NOMA system was presented.22 Moreover, under the assumption of random beamforming, the performance of NOMA system was investigated without power allocation.23 In addition, ...
Finite field arithmetic operations have been widely used in the areas of data communication and network security applications, and high-speed and low-complexity design for finite field arithmetic is very necessary for these applications. This paper prese
