Algorithms

In mathematics and computer science, an algorithm is a finite sequence of
well-defined, computer-implementable instructions, typically to

solve a class of specific problems or to perform a computation.

What is an example of an algorithm?

One of the most obvious examples of an algorithm is a recipe. It's a finite list of instructions used to perform a task. For example, if you were to follow the algorithm to create brownies from a box mix, you would follow the three to five step process written on the back of the box.


What are the characteristics of algorithm?

Algorithm and its characteristics

  • Finiteness. An algorithm must always terminate after a finite number of steps.

  • Definiteness. Each step of an algorithm must be precisely defined; the actions to be carried out must be rigorously and unambiguously specified for each case.

  • Input

  • Output

  • Effectiveness.


What are the 5 properties of algorithm?

An algorithm must have five properties:

  • Input specified.

  • Output specified.

  • Definiteness.

  • Effectiveness.

  • Finiteness.


What are the types of algorithms?

Algorithm types we will consider include:

  • Simple recursive algorithms.

  • Backtracking algorithms.

  • Divide and conquer algorithms.

  • Dynamic programming algorithms.

  • Greedy algorithms.

  • Branch and bound algorithms.

  • Brute force algorithms.

  • Randomized algorithms.



What is Big O function?

Big O notation is a mathematical notation that describes the limiting behavior of a function when the argument tends towards a particular value or infinity. ... In computer science, big O notation is used to classify algorithms according to how their run time or space requirements grow as the input size grows.
