Ghost (game)
Ghost (also known as ghosts or endbee) is a written or spoken word game in which players take turns adding letters to a growing word fragment, trying not to be the one to complete a valid word. Each fragment must be the beginning of an actual word, and usually some minimum is set on the length of a word that counts, such as three or four letters. The player who completes a word loses the round and earns a "letter" (as in the basketball game horse), with players being eliminated when they have been given all five letters of the word "ghost". Ghost can be played by two or more players and requires no equipment, although it can be played with pencil and paper instead of being spoken aloud. The player whose turn it is may — instead of adding a letter — challenge the previous player to prove that the current fragment is actually the beginning of a word. If the challenged player can name such a word, the challenger loses the round; otherwise the challenged player loses the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Word Game
Word games (also called word game puzzles or word search games) are spoken, board, or video games often designed to test ability with language or to explore its properties. Word games are generally used as a source of entertainment, but can additionally serve an educational purpose. Young children can enjoy playing games such as Hangman, while naturally developing important language skills like spelling. Researchers have found that adults who regularly solved crossword puzzles, which require familiarity with a larger vocabulary, had better brain function later in life. Popular word-based game shows have been a part of television and radio throughout broadcast history, including '' Spelling Bee'', the first televised game show, and ''Wheel of Fortune'', the longest-running syndicated game show in the United States. Categories of word game Letter arrangement games In a letter arrangement game, the goal is to form words out of given letters. These games generally test vocab ...

Daniel Asimov
Daniel is a masculine given name and a surname of Hebrew origin. It means "God is my judge"Hanks, Hardcastle and Hodges, ''Oxford Dictionary of First Names'', Oxford University Press, 2nd edition, , p. 68. (cf. Gabriel—"God is my strength"), and derives from two early biblical figures, primary among them Daniel from the Book of Daniel. It is a common given name for males, and is also used as a surname. It is also the basis for various derived given names and surnames. Background The name evolved into over 100 different spellings in countries around the world. Nicknames (Dan, Danny) are common in both English and Hebrew; "Dan" may also be a complete given name rather than a nickname. The name "Daniil" (Даниил) is common in Russia. Feminine versions (Danielle, Danièle, Daniela, Daniella, Dani, Danitza) are prevalent as well. It has been particularly well-used in Ireland. The Dutch names "Daan" and "Daniël" are also variations of Daniel. A related surname developed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Unhalfbricking
''Unhalfbricking'' is the third album by the British folk rock band Fairport Convention and their second album released in 1969. It is seen as a transitional album in their history and marked a further musical move away from American influences towards more traditional English folk songs that had begun on their previous album, ''What We Did on Our Holidays'' and reached its peak on the follow-up, ''Liege & Lief'', released later the same year. The album features several Bob Dylan songs, which he had not yet released. It also features what is arguably Sandy Denny's most notable achievement as a songwriter with the song "Who Knows Where the Time Goes?", which has been covered by many other performers and is now regarded as a classic. The only traditional song on the album, "A Sailor's Life", is seen as pivotal in the development of English folk rock music. Changes in the line-up of the band, due not only to its musical direction but also to external events, mark this album as a tu ...

Nondeterministic Finite Automaton
In automata theory, a finite-state machine is called a deterministic finite automaton (DFA), if * each of its transitions is ''uniquely'' determined by its source state and input symbol, and * reading an input symbol is required for each state transition. A nondeterministic finite automaton (NFA), or nondeterministic finite-state machine, does not need to obey these restrictions. In particular, every DFA is also an NFA. Sometimes the term NFA is used in a narrower sense, referring to an NFA that is ''not'' a DFA, but not in this article. Using the subset construction algorithm, each NFA can be translated to an equivalent DFA; i.e., a DFA recognizing the same formal language. Like DFAs, NFAs only recognize regular languages. NFAs were introduced in 1959 by Michael O. Rabin and Dana Scott, who also showed their equivalence to DFAs. NFAs are used in the implementation of regular expressions: Thompson's construction is an algorithm for compiling a regular expression to an NFA that ...

Generalized Geography
In computational complexity theory, generalized geography is a well-known PSPACE-complete problem. Introduction Geography is a children's game, where players take turns naming cities from anywhere in the world. Each city chosen must begin with the same letter that ended the previous city name. Repetition is not allowed. The game begins with an arbitrary starting city and ends when a player loses because he or she is unable to continue. Graph model To visualize the game, a directed graph can be constructed whose nodes are each cities of the world. An arrow is added from node ''N''1 to node ''N''2 if and only if the city labeling ''N''2 starts with the letter that ending the name of the city labeling node ''N''1. In other words, we draw an arrow from one city to another if the first can lead to the second according to the game rules. Each alternate edge in the directed graph corresponds to each player (for a two player game). The first player unable to extend the path loses. An ill ...

PSPACE-hard
In computational complexity theory, PSPACE is the set of all decision problems that can be solved by a Turing machine using a polynomial amount of space. Formal definition If we denote by SPACE(''t''(''n'')), the set of all problems that can be solved by Turing machines using ''O''(''t''(''n'')) space for some function ''t'' of the input size ''n'', then we can define PSPACE formally asArora & Barak (2009) p.81 :\mathsf = \bigcup_ \mathsf(n^k). PSPACE is a strict superset of the set of context-sensitive languages. It turns out that allowing the Turing machine to be nondeterministic does not add any extra power. Because of Savitch's theorem,Arora & Barak (2009) p.85 NPSPACE is equivalent to PSPACE, essentially because a deterministic Turing machine can simulate a non-deterministic Turing machine without needing much more space (even though it may use much more time).Arora & Barak (2009) p.86 Also, the complements of all problems in PSPACE are also in PSPACE, meaning that ...

EXPSPACE
In computational complexity theory, is the set of all decision problems solvable by a deterministic Turing machine in exponential space, i.e., in O(2^) space, where p(n) is a polynomial function of n. Some authors restrict p(n) to be a linear function, but most authors instead call the resulting class . If we use a nondeterministic machine instead, we get the class , which is equal to by Savitch's theorem. A decision problem is if it is in , and every problem in has a polynomial-time many-one reduction to it. In other words, there is a polynomial-time algorithm that transforms instances of one to instances of the other with the same answer. problems might be thought of as the hardest problems in . is a strict superset of , , and and is believed to be a strict superset of .

Regular Language
In theoretical computer science and formal language theory, a regular language (also called a rational language) is a formal language that can be defined by a regular expression, in the strict sense in theoretical computer science (as opposed to many modern regular expressions engines, which are augmented with features that allow recognition of non-regular languages). Alternatively, a regular language can be defined as a language recognized by a finite automaton. The equivalence of regular expressions and finite automata is known as Kleene's theorem (after American mathematician Stephen Cole Kleene). In the Chomsky hierarchy, regular languages are the languages generated by Type-3 grammars. Formal definition The collection of regular languages over an alphabet Σ is defined recursively as follows: * The empty language Ø is a regular language. * For each ''a'' ∈ Σ (''a'' belongs to Σ), the singleton language is a regular language. * If ''A'' is a regular language, ''A''* ( ...

Regular Expression
A regular expression (shortened as regex or regexp; sometimes referred to as rational expression) is a sequence of characters that specifies a search pattern in text. Usually such patterns are used by string-searching algorithms for "find" or "find and replace" operations on strings, or for input validation. Regular expression techniques are developed in theoretical computer science and formal language theory. The concept of regular expressions began in the 1950s, when the American mathematician Stephen Cole Kleene formalized the concept of a regular language. They came into common use with Unix text-processing utilities. Different syntaxes for writing regular expressions have existed since the 1980s, one being the POSIX standard and another, widely used, being the Perl syntax. Regular expressions are used in search engines, in search and replace dialogs of word processors and text editors, in text processing utilities such as sed and AWK, and in lexical analysis.

I'm Sorry I Haven't A Clue
''I'm Sorry I Haven't a Clue'' is a BBC radio comedy panel game. Billed as "the antidote to panel games", it consists of two teams of two comedians being given "silly things to do" by a chairman. The show was launched in April 1972 as a parody of radio and TV panel games, and has been broadcast since on BBC Radio 4 and the BBC World Service, with repeats aired on BBC Radio 4 Extra and, in the 1980s and 1990s, on BBC Radio 2. The 50th series was broadcast in November and December 2007. After a period of split chairmanship in the first series, Humphrey Lyttelton ("Humph") served in this role from the programme's inception until his hospitalisation and subsequent death in 2008, which led to the cancellation of the 51st series. The show recommenced on 15 June 2009 with Lyttelton replaced by three hosts: Stephen Fry, Jack Dee and Rob Brydon. Dee went on to host all episodes of the 52nd series later that year, and continues in that role. The chairman's script was most recently written ...
