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.
Pseudocode is an informal high-level description of the operating principle of a computer program or other algorithm.
It uses the structural conventions of a programming language, but is intended for human reading rather than machine reading. Pseudocode typically omits details that are essential for machine understanding of the algorithm, such as variable declarations, system-specific code and some subroutines. The programming language is augmented with natural language description details, where convenient, or with compact mathematical notation. The purpose of using pseudocode is that it is easier for people to understand than conventional programming language code, and that it is an efficient and environment-independent description of the key principles of an algorithm. It is commonly used in textbooks and scientific publications that are documenting various algorithms, and also in planning of computer program development, for sketching out the structure of the program before the actual coding takes place.
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 2^{n} - 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.

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...
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.

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.

My goal is to provide you with actionable information to improve your eBay store. -1. Overall Store Brand: do you have an item that people want, and do they trust you to buy the item. Are pictures bright enough? Is the pricing accurage -2. Sell popular versus cheap. The heaviest sales are amongst the best products. Rather than sell cheap random stuff, you should shift towards selling popular items and brands. I only have a limited amount of money, so I shoot for the most popular items I can afford. Most people work sooo hard to get their junk online, and don't realize that the market doesn't care. They still want the popular items. -3.

In this Coding Challenge, I attempt an implementation of the A* pathfinding algorithm to find the optimal path between two points in a 2D grid. I begin by explaining the mechanics of how the algorithm works, look at pseudo-code, and then write the algorithm in JavaScript using the p5.js library for rendering. Part 2 focuses on adding obstacles (walls) to the grid as well as functionality for moving diagonally. . In Part 3, I look at ways to improve the visual design and invite you to put your own spin on it.
