## Which is an example of online algorithm?

Thus insertion sort is an online algorithm. EXAMPLE OF ONLINE ALGORITHM (INSERTION SORT): Because an online algorithm does not know the whole input, it might make decisions that later turn out not to be optimal, Note that insertion sort produces the optimum result.

What are algorithms problems?

The problem of finding a (unique) method (an algorithm) to solve an infinite series of individual problems of the same type. Algorithmic problems arose and were solved in various branches of mathematics throughout its history; however, some of them could not be solved for a long time.

What is a kserver?

The k -server problem is a problem of theoretical computer science in the category of online algorithms, one of two abstract problems on metric spaces that are central to the theory of competitive analysis (the other being metrical task systems).

### What do you mean by an online algorithm?

In computer science, an online algorithm is one that can process its input piece-by-piece in a serial fashion, i.e., in the order that the input is fed to the algorithm, without having the entire input available from the start. Thus insertion sort is an online algorithm.

Why insertion sort is online algorithm?

Insertion sort, by contrast, is online because it does not need to know anything about what values it will sort and the information is requested WHILE the algorithm is running. Simply put, it can grab new values at every iteration.

What problems are solved by algorithms?

Algorithms are commonly used to solve certain types of computational problems. We can often describe such a problem by specifying a relationship between input and output. The sorting problem, for example, can be described like this: Input: a sequence a1, a2., an of n numbers.

## What is the difference between problem and algorithms?

To summarize: A problem is a function or a mapping of inputs to outputs. An algorithm is a recipe for solving a problem whose steps are concrete and unambiguous. Algorithms must be correct, of finite length, and must terminate for all inputs. A program is an instantiation of an algorithm in a programming language.

What is difference between bubble sort and insertion sort?

The main difference between bubble sort and insertion sort is that bubble sort performs sorting by checking the neighboring data elements and swapping them if they are in wrong order while insertion sort performs sorting by transferring one element to a partially sorted array at a time.

How do algorithms work on Facebook?

How does the Facebook algorithm work these days? The Facebook algorithm controls the ordering and presentation of posts, so users see what is most relevant to them. Rather than publish content chronologically, posts and ads are presented based on what Facebook sees as relevant to you, the user.

### Why is the social media algorithm bad?

Bias Media or Articles: “They (social networks) align content and advertising around what the algorithm deems important to us. They stoke our cognitive biases, said or unsaid vulnerabilities. And they create engagement or activity around those things because they are extremely charged.

What is the difference between a problem and an algorithm?

To summarize: A problem is a function or a mapping of inputs to outputs. An algorithm is a recipe for solving a problem whose steps are concrete and unambiguous. Algorithms must be correct, of finite length, and must terminate for all inputs.

What is an online algorithm?

An online algorithm is one that can process its input piece-by-piece in a serial fashion, i.e., in the order that the input is fed to the algorithm, without having the entire input available from the beginning.

## What are the disadvantages of algorithms?

In Algorithm the problem is broken down into smaller pieces or steps hence, it is easier for the programmer to convert it into an actual program. Writing an algorithm takes a long time so it is time-consuming. Branching and Looping statements are difficult to show in Algorithms.

How do you write an algorithm?

In order to write an algorithm, following things are needed as a pre-requisite: The problem that is to be solved by this algorithm. The constraints of the problem that must be considered while solving the problem. The input to be taken to solve the problem.

How are algorithms generated?

After all, algorithms are generated by trial and error, by testing, by observing, and coming to certain mathematical formulae regarding choices that have been made again and again – and this can be used for difficult choices and problems, especially when intuitively we cannot readily see an answer or a way to resolve the problem.
