Webtially the successive doubling algorithm mentioned above and takes N log, N operations. The 23-year hiatus in the use of the algorithm seemed quite remarkable, and prompted us to inquire of Prof. L. H. Thomas at the IBM Watson Scientific Computing Laboratory, New York, N. Y., as to whether he was familiar WebThe double-and-add algorithm is a simple and efficient way to perform scalar multiplication on elliptic curves. It works by repeatedly doubling the current point and adding it to the result if a certain bit in the binary representation of the scalar value is 1. This process can be performed in logarithmic time, which means that it is very fast ...
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 WebMar 8, 2013 · Doubling or tripling algorithms has been used in older days to reuse previous algorithms which were definitely too weak on their own; the prime example is Triple-DES (aka "3DES"), built over the previous DES. DES and its 56-bit key space is vulnerable to exhaustive search (it has been done ).
WebOct 20, 2024 · But for example, if we take N<10 6 then in the best case, the double logarithmic algorithm surpasses the logarithmic one by approximately a factor of 5. 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! WebMar 1, 2024 · In this paper, we have proposed a structure-preserving doubling algorithm and two modified structure-preserving doubling algorithms of the positive definite solutions …
WebOne reason for doubling size that is specific to hash containers is that if the container capacity is always a power of two, then instead of using a general purpose modulo for converting a hash to an offset, the same result can be achieved with bit shifting. Modulo is a slow operation for the same reasons that integer division is slow.
