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.
The Tower of Hanoi (also called the Tower of Brahma or Lucas' Tower, and sometimes pluralized) is a mathematical game or puzzle. It consists of three rods, and a number of disks of different sizes which can slide onto any rod. The puzzle starts with the disks in a neat stack in ascending order of size on one rod, the smallest at the top, thus making a conical shape.
The objective of the puzzle is to move the entire stack to another rod, obeying the following simple rules:
With three disks, the puzzle can be solved in seven moves. The minimum number of moves required to solve a Tower of Hanoi puzzle is 2n - 1, where n is the number of disks.
The puzzle was invented by the French mathematician Édouard Lucas in 1883. There is a story about an Indian temple in Kashi Vishwanath which contains a large room with three time-worn posts in it surrounded by 64 golden disks. Brahmin priests, acting out the command of an ancient prophecy, have been moving these disks, in accordance with the immutable rules of the Brahma, since that time. The puzzle is therefore also known as the Tower of Brahma puzzle. According to the legend, when the last move of the puzzle will be completed, the world will end. It is not clear whether Lucas invented this legend or was inspired by it.
Part 3 is the fourth studio album by the funk and disco group KC and the Sunshine Band. The album was produced by Harry Wayne Casey and Richard Finch and was released in October 1976 on the TK label.
Part 3 contains three of the band's biggest hits, "(Shake, Shake, Shake) Shake Your Booty", "I'm Your Boogie Man", and "Keep It Comin' Love". The first two reached #1 on the Billboard Hot 100 while the third peaked at number two. Two other singles, "I Like to Do It" and "Wrap Your Arms Around Me" found moderate success on the charts. The album was remastered and reissued in 2006 by Collector's Choice Music.
All songs written and composed by Harry Wayne Casey and Richard Finch.
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.
Dijkstra's algorithm is an algorithm for finding the shortest paths between nodes in a graph, which may represent, for example, road networks. It was conceived by computer scientist Edsger W. Dijkstra in 1956 and published three years later.
The algorithm exists in many variants; Dijkstra's original variant found the shortest path between two nodes, but a more common variant fixes a single node as the "source" node and finds shortest paths from the source to all other nodes in the graph, producing a shortest-path tree.
For a given source node in the graph, the algorithm finds the shortest path between that node and every other. It can also be used for finding the shortest paths from a single node to a single destination node by stopping the algorithm once the shortest path to the destination node has been determined. For example, if the nodes of the graph represent cities and edge path costs represent driving distances between pairs of cities connected by a direct road, Dijkstra's algorithm can be used to find the shortest route between one city and all other cities. As a result, the shortest path algorithm is widely used in network routing protocols, most notably IS-IS and Open Shortest Path First (OSPF). It is also employed as a subroutine in other algorithms such as Johnson's.

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.
DEVIL'S ALGORITHM FOUND WUT WUT! YES, this IS a joke. NO, this DOES NOT work. This is an April Fools' Day joke, and the video happened to gain views past its expected timeframe. It's a play on words because A-perm FULS sounds like "April Fools." In case you're curious, I do know that devil's algorithms (Hamiltonian circuits) have been found before. I was relying on the fact that most of you wouldn't know, hehehehe!! Frequently Asked Questions: Q: Why did you upload a day early? A: I didn't. I scheduled the video to go up on April 1st, 2015, at 1:00 in the morning. It did go up then, but YouTube glitched out and has said that it went up on March 31st ever since. Not sure exactly why. Q: What cube is that? A: It's a YJ GuanLong. It's not my main or anything; it was just on my desk when I...
Here I explain how to get the Rubik's cube solved in 3 sides and mixed in the other 3 sides. Please share with your friends and prank them. Let me know how was it in the comments.
Tower of Hanoi is a very famous game. In this game there are 3 pegs and N number of disks placed one over the other in decreasing size. The objective of this game is to move the disks one by one from the first peg to the last peg. And there is only ONE condition, we can not place a bigger disk on top of a smaller disk.

Discusses how to use the classic Dijkstra's algorithm to determine the best way to route packets in a network. Dijkstra's algorithm can find the shortest paths between nodes in a directed graph, and thus can be applied to networks. However, the amount of information required by each router makes applying this algorithm in an actual network more difficult.
