In mathematics and computer science, an algorithm (^{i}/ˈælɡərɪðəm/ AL-gə-ri-dhəm) is a self-contained step-by-step set of operations to be performed. Algorithms exist that perform calculation, data processing, and automated reasoning.
The words 'algorithm' and 'algorism' come from the name al-Khwārizmī. Al-Khwārizmī (Persian: خوارزمي, c. 780-850) was a Persian mathematician, astronomer, geographer, and scholar.
An algorithm is an effective method that can be expressed within a finite amount of space and time and in a well-defined formal language for calculating a function. Starting from an initial state and initial input (perhaps empty), the instructions describe a computation that, when executed, proceeds through a finite number of well-defined successive states, eventually producing "output" and terminating at a final ending state. The transition from one state to the next is not necessarily deterministic; some algorithms, known as randomized algorithms, incorporate random input.
Rubik's Cube is a 3-D combination puzzle invented in 1974 by Hungarian sculptor and professor of architecture Ernő Rubik. Originally called the Magic Cube, the puzzle was licensed by Rubik to be sold by Ideal Toy Corp. in 1980 via businessman Tibor Laczi and Seven Towns founder Tom Kremer, and won the German Game of the Year special award for Best Puzzle that year. As of January 2009, 350 million cubes had been sold worldwide making it the world's top-selling puzzle game. It is widely considered to be the world's best-selling toy.
In a classic Rubik's Cube, each of the six faces is covered by nine stickers, each of one of six solid colours: white, red, blue, orange, green, and yellow. In currently sold models, white is opposite yellow, blue is opposite green, and orange is opposite red, and the red, white and blue are arranged in that order in a clockwise arrangement. On early cubes, the position of the colours varied from cube to cube. An internal pivot mechanism enables each face to turn independently, thus mixing up the colours. For the puzzle to be solved, each face must be returned to have only one colour. Similar puzzles have now been produced with various numbers of sides, dimensions, and stickers, not all of them by Rubik.

It's possible to use one simple set of moves to solve any scrambled Rubik's Cube! And it's easy to remember! Algorithm: L R2 B L' R U2 F2 L B D U2 B L' R2 B2 L' D2 U L' B2 U2 R2 B D2... psych! This video is a complete joke. 100% made up! There is no special 'trick' or lazy guys method for solving a Rubik's Cube. This video was made as a response to obnoxious people who belittle people who have worked for years to solve the cube at incredibly fast times by claiming theres just a "trick". If you have a Rubik's cube and you genuinely want to solve it then use the video I used to learn here: https://www.youtube.com/watch?v=HsQIoPyfQzM That is a genuine Rubik's Cube tutorial that WILL teach you the beginners method to solving a Rubik's Cube.
In this video lecture we are going to explain the Rice Codes Algorithm Step by Step with Numerical Example.

In this video we will learn about Floyd's Algorithm to find all pair shortest path for a given graph. CODE LINK: https://goo.gl/BFuEq1 Subscribe: http://goo.gl/cFA9in In this video we have a non-directed graph which means if we have an edge connecting vertex A and B then we can use that edge to travel from vertex A to B and from vertex B to A. So, the edge is basically like a two way road connecting two cities A and B.

There are 2 types of Routing Algorithm a)Adaptive b)Non Adaptive. Adaptive Routing Algorithm These algorithm change their Routing decisions to reflect the changes in topology & traffic. This algorithm is also called dynamic Routing. This algorithm is classified into a)Centralized b) Isolated c) Distributed. Non Adaptive Routing Algorithm These algorithm do not change their Routing decisions on measurement & estimates of current traffic & topology. These routing decisions are made in advance & off line. They can be classified into a)flooding b)Random walk.

The video shows the contour reduction operation described in paper Macromolecules 2006, vol. 39, pg. 4592-4604, which is able to reveal the underlying entanglement structure of a flexible polymer melt. The initial configuration is atomistic polyethylene, 8 chains, with full periodic boundary conditions applied. Chain ends are fixed in space, and by prohibiting chain crossing, the contour lengths of all chains are simultaneously minimized (shrunk), until they become sets of rectilinear strands coming together at the nodal points of a network. The nodal points are the Topological Constraints generated by chain uncrossability. As the algorithm proceeds, and in order to facilitate contour reduction through the removal of unentangled loops, chain thickness is progressively reduced t...

'Explorer 4.0b' Ultra-HD Maze generating algorithm solved with A* Pathfinder algorithm. 1st, we generate a perfect, high-def maze using our Explorer algorithm developed by ailabs.co.za in Python, then we solve it (finding shortest route from start to finish) using A* pathfinding method. To speed up performance, screen is only updated every 1000th loop iteration. Actual time generating & solving on Intel i7 8700 / 16GB DDR4 PC took about 12 minutes! (A "perfect" Maze means one with only one solution without any loops or closed circuits, and without any inaccessible areas.)

Get the Code Here: http://goo.gl/Y3UTH Welcome to my Big O Notations tutorial. Big O notations are used to measure how well a computer algorithm scales as the amount of data involved increases. It isn't however always a measure of speed as you'll see. This is a rough overview of Big O and I hope to simplify it rather than get into all of the complexity. I'll specifically cover the following O(1), O(N), O(N^2), O(log N) and O(N log N). Between the video and code below I hope everything is completely understandable.

Several examples of KMP in action, with real time explanations of how and why the algorithm works. MISTAKES: - In the beginning I mistakenly write my pattern as 'aaab' - it should read 'aaaa'. - At 10:49 I mistakenly draw the bar indicating a suffix too far into the pattern - it should be the suffix immediately following 'b'. - When you get a mismatch in the search, if you fail at index i of your pattern, you don't go to the index indicated at index i of the failure array to resume the search - it's index (i-1). So you go back one in the failure array, and THAT index will lead you to the correct location in the pattern to resume the search.
