League of Legends Championship Series

The League of Legends Championship Series (LCS), formerly known as the Riot Championship Series, is the name of two professional League of Legends eSports leagues run by Riot Games. Twenty teams compete in two separate competitions in North America and Europe, with ten teams per continent. Each annual season of play is divided into two splits, spring and summer, both consisting of nine weeks of round-robin tournament play, which then conclude with play-off tournaments between the top six teams from each region. At the end of the season, the highest placing three teams in each league qualify for the annual League of Legends World Championship.

The LCS represents the highest level of League of Legends play in Europe and North America. The LCS has a promotion and relegation system; the bottom teams in the LCS from each split compete with the top teams from the Challenger Series (CS) to compete for spots in the next split of the LCS. The Challenger Series in each continent is composed of six teams: three teams which failed to advance in the previous promotion tournament, one team from the previous CS split, and the top two teams from ranked ladder play in the respective public League of Legends online game server.

APX

In complexity theory the class APX (an abbreviation of "approximable") is the set of NP optimization problems that allow polynomial-time approximation algorithms with approximation ratio bounded by a constant (or constant-factor approximation algorithms for short). In simple terms, problems in this class have efficient algorithms that can find an answer within some fixed multiplicative factor of the optimal answer.

An approximation algorithm is called a -approximation algorithm for input size if it can be proven that the solution that the algorithm finds is at most a multiplicative factor of times worse than the optimal solution. Here, is called the approximation ratio. Problems in APX are those with algorithms for which the approximation ratio is a constant . The approximation ratio is conventionally stated greater than 1. In the case of minimization problems, is the found solution's score divided by the optimum solution's score, while for maximization problems the reverse is the case. For maximization problems, where an inferior solution has a smaller score, is sometimes stated as less than 1; in such cases, the reciprocal of is the ratio of the score of the found solution to the score of the optimum solution.

BattleBlock Theater

BattleBlock Theater is a comedy platform game developed by The Behemoth and published by Microsoft Studios for Xbox 360, Windows, Mac, and Linux. It is the third title from The Behemoth following Alien Hominid and Castle Crashers. The game was released on Xbox Live Arcade on April 3, 2013, and later temporarily made free via Games with Gold on July 16, 2014.

Story

Almost all of the game's cut-scenes are done in a stick puppet style. The game begins with the narrator (voiced by Will Stamper) telling the adventures of the hundreds of friends aboard the S.S. Friendship, as well as Hatty Hattington, who is known as "best friend to one and all". After encountering a heavy storm, the S.S. Friendship becomes shipwrecked on a mysterious, seemingly abandoned island, and the crew itself vanishes. Upon waking up from the wreck, the player character seeks shelter from the storm in a dilapidated theater.

Upon coming to, it is revealed that the entire crew of the S.S. Friendship is being held prisoner by cats, with Hatty as their apparent new leader. The player is then released from their cell and forced into deadly games by the feline wardens. The cats, who force their prisoners into deadly theater performances, watch with amusement as the player fights for their survival. As the player completes challenges, they find gems which are spent on unlocking fellow crew members to play as in these theater performances. Appearing to be possessed by the hat's unknown powers, Hatty begins working for the cats and against the player.

Android (operating system)

Android (from its former owner Android, Inc.) is a mobile operating system (OS) currently developed by Google, based on the Linux kernel and designed primarily for touchscreen mobile devices such as smartphones and tablets. Android's user interface is mainly based on direct manipulation, using touch gestures that loosely correspond to real-world actions, such as swiping, tapping and pinching, to manipulate on-screen objects, along with a virtual keyboard for text input. In addition to touchscreen devices, Google has further developed Android TV for televisions, Android Auto for cars, and Android Wear for wrist watches, each with a specialized user interface. Variants of Android are also used on notebooks, game consoles, digital cameras, and other electronics.

Since 2013, Android is the best selling on tablets; and on smartphones the OS is dominant, thereby giving it the largest installed base of all operating systems of any kind.

Initially developed by Android, Inc., which Google bought in 2005, Android was unveiled in 2007, along with the founding of the Open Handset Alliance – a consortium of hardware, software, and telecommunication companies devoted to advancing open standards for mobile devices.As of July 2013, the Google Play store has had over one million Android applications ("apps") published, and over 50 billion applications downloaded. An April–May 2013 survey of mobile application developers found that 71% of developers create applications for Android, and a 2015 survey found that 40% of full-time professional developers see Android as their priority target platform, which is comparable to Apple's iOS on 37% with both platforms far above others. At Google I/O 2014, the company revealed that there were over one billion active monthly Android users, up from 538 million in June 2013.

Game

A game is structured form of play, usually undertaken for enjoyment and sometimes used as an educational tool. Games are distinct from work, which is usually carried out for remuneration, and from art, which is more often an expression of aesthetic or ideological elements. However, the distinction is not clear-cut, and many games are also considered to be work (such as professional players of spectator sports or games) or art (such as jigsaw puzzles or games involving an artistic layout such as Mahjong, solitaire, or some video games).

Key components of games are goals, rules, challenge, and interaction. Games generally involve mental or physical stimulation, and often both. Many games help develop practical skills, serve as a form of exercise, or otherwise perform an educational, simulational, or psychological role.

Attested as early as 2600 BC, games are a universal part of human experience and present in all cultures. The Royal Game of Ur, Senet, and Mancala are some of the oldest known games.
