And also, in general, its implementation is more difficult. Now, in the real world, a factor of 5 is very significant and hence, a speed-up by a factor of that number is huge!
Doubling algorithm
Did you know?
WebA structured doubling algorithm is proposed for large-scale problems when A is of lowrank. Compared to the existing doubling algorithm of flops at the k -th iteration, the newly developed version merely needs flops for preprocessing and flopsfor iterations and is more proper for large-scale computations when . WebA new doubling algorithm—the alternating-directional doubling algorithm (ADDA)—is developed for computing the unique minimal nonnegative solution of an M-matrix algebraic Riccati equation (MARE).It is argued by both theoretical analysis and numerical experiments that ADDA is always faster than two existing doubling algorithms: SDA of Guo, Lin, and Xu …
WebJan 1, 2007 · The doubling algorithm is considered for finding the minimal nonnegative solution, the one of practical interest. The algorithm has been recently studied by others … In computer science, an exponential search (also called doubling search or galloping search or Struzik search) is an algorithm, created by Jon Bentley and Andrew Chi-Chih Yao in 1976, for searching sorted, unbounded/infinite lists. There are numerous ways to implement this, with the most common being to determine a … See more Exponential search allows for searching through a sorted, unbounded list for a specified input value (the search "key"). The algorithm consists of two stages. The first stage determines a range in which the search key would … See more An algorithm based on exponentially increasing the search band solves global pairwise alignment for O(ns), where n is the length of the sequences and s is the edit distance between them. See more The first stage of the algorithm takes O(log i) time, where i is the index where the search key would be in the list. This is because, in … See more Bentley and Yao suggested several variations for exponential search. These variations consist of performing a binary search, as opposed … See more • Linear search • Binary search • Interpolation search • Ternary search • Hash table See more
WebNov 1, 2024 · Using this model for the recursive doubling with pairwise exchange algorithm results in a total cost of: (1) ( α + n β + n γ) × log 2 N N = 2 k, k ∈ N. The first term is the cost per stage of the AllReduce while the second term is the number of stages which will be performed. The MPICH fix simply adds two stages to the logarithmic term. WebDouble Ratchet Algorithm. In cryptography, the Double Ratchet Algorithm (previously referred to as the Axolotl Ratchet [1] [2]) is a key management algorithm that was developed by Trevor Perrin and Moxie Marlinspike in 2013. It can be used as part of a cryptographic protocol to provide end-to-end encryption for instant messaging.
