7.3. Introduction to Probabilistic Algorithms — Senior Algorithms
Nov 18, 2024 · Here is an example of an algorithm for finding a large value that gives up its guarantee of getting the best value in exchange for an improved running time. This is an example of a probabilistic algorithm, since it includes steps that are affected by random events.
Introduction to Parallel Algorithms - Online Tutorials Library
Explore the fundamentals of parallel algorithms, their importance, and applications in computing. Learn how parallel processing can enhance performance and efficiency.
We begin in Section 1 with a discussion of how to model parallel computers. Next, in Section 2 we cover some general techniques that have proven useful in the design of parallel algorithms. Sections 3 through 7 present algorithms for solving problems from different domains.
It is also common in parallel algorithms to divide the original problem in to as man y subproblems as p ossible, so that they can all b e solv ed in parallel. As an example of parallel divide-and-conquer, consider the sequen tial mergesort algorithm.
In this section, we present parallel graph algorithms for breadth- rst search, low-diameter decomposition, connectivity, maximal independent set and minimum span-ning tree which illustrate useful techniques in parallel algorithms such …
The section will conclude with the presentation of a strongly optimal deterministic parallel algorithm and illustrate a powerful technique used in the design of parallel algorithms, accelerating cascades.
10 Randomization in Parallel Algorithms | Probability and Algorithms …
In this chapter, we define a natural randomized parallel complexity class, RNC, and give a survey of randomized algorithms for problems in this class. In recent years, there has been an explosive growth in the availability and diversity of parallel processors for computation.
