Feb 24, 2025 · Deterministic algorithms are entirely predictable and always produce the same output for the same input. Non-deterministic algorithms may produce different outputs for the same input due to random events or other factors. Deterministic algorithms usually provide precise solutions to problems.

We start with a discussion of the diferences between randomized algorithms and deterministic algorithms. We then introduce the two primary types of randomized algorithms: Las Vegas algorithms and Monte Carlo algorithms. This chapter and its exercises will contain many examples of randomized algorithms, all of the Las Vegas variety.

Probabilistic algorithm which don't use any coin tosses are sometimes called "deterministic". Non-deterministic algorithms are ones which "need a hint" but are always correct: they cannot be fooled by being given the wrong hint.

There are a few standard techniques that can sometimes convert a randomized algorithm to a deterministic one. These techniques do not always work; and derandomization is a big topic.

One important (and exclusive) distinction one can make is, whether the algorithm is deterministic or randomized. Deterministic algorithms produce on a given input the same results following the same computation steps. Ran-domized algorithms throw coins during execution.

Randomized algorithms are classified based on whether they have time constraints as the random variable or deterministic values. They are designed in their two common forms − Las Vegas and Monte Carlo.

Sep 16, 2023 · Deterministic and randomized algorithms are two fundamental categories of algorithms in computer science, and they differ in how they make decisions or perform computations. Let’s first explore...

What is a randomized algorithm? based on r’s value. Randomized algorithms can be broadly classified into two types- Monte Carlo and Las Vegas. Simple algorithm: O(n3) multiplications. A B = C or not. Question. Can we do better than carrying out the full multiplication? We will see an O(n2) algorithm that: if A B = C, then P r[output=YES] = 1.

a randomized algorithm can be seen as a probabilistic distribution over deterministic algorithms, i.e., as mixed strategy for the algorithm player faced with a mixed
