One of the most well-known randomized algorithms in DAA is the randomized quicksort algorithm. This algorithm improves upon the classical quicksort algorithm by choosing a random pivot element instead of a fixed one. This makes the algorithm less likely to encounter worst- case scenarios where the input array is already sorted or nearly sorted.

A Simple Example: Choosing a Large Number. Given nnumbers, find a number that is ≥ me dian. Simple deterministic algorithm takes O(n) time. A simple randomized algorithm: Choose knumbers randomly, k< n, and output the maximum. Runs faster. …
Lecture 6: Randomized Algorithms • Check matrix multiplication • Quicksort. Randomized or Probablistic Algorithms. What is a randomized algorithm? • Algorithm that generates a random number. r ∈{1, ..., R} and makes decisions based on. r ’s value. • On the same input on different executions, a randomized algorithm may – Run a ...
An algorithm that incorporates randomness as part of its operation. Basically, we’ll make random choices during the algorithm: Sometimes, we’ll just hope that our algorithm is fast! Other times, we’ll just hope that it works! Let’s formalize this... What is a Randomized Algorithm? 3 3
Why randomized algorithms? 1 Many many applications in algorithms, data structures and computer science! 2 In some cases only known algorithms are randomized or randomness is provably necessary. 3 Often randomized algorithms are (much) simpler and/or more ecient. 4 Several deep connections to mathematics, physics etc. 5... 6 Lots of fun!
CS787: Advanced Algorithms Lecture 6: Randomized Algorithms In this lecture we introduce randomized algorithms. We will begin by motivating the use of ran-domized algorithms through a few examples. Then we will revise elementary probability theory, and conclude with a fast randomized algorithm for computing a min-cut in a graph, due to David ...

Randomized Algorithms An algorithm that uses random numbers to decide what to do next anywhere in its logic is called Randomized Algorithm. For example, in Randomized Quick Sort, we use a random number to pick the next pivot (or we randomly shuffle the array).
