Production (computer science)
A production or production rule in computer science is a rewrite rule specifying a symbol substitution that can be recursively performed to generate new symbol sequences. A finite set of productions 
is the main component in the specification of a formal grammar (specifically a generative grammar). The other components are a finite set 
of nonterminal symbols, a finite set (known as an alphabet) 
of terminal symbols that is disjoint from and a distinguished symbol 
that is the start symbol.
In an unrestricted grammar, a production is of the form 
where 
and 
are arbitrary strings of terminals and nonterminals however may not be the empty string. If is the empty string, this is denoted by the symbol 
, or 
(rather than leave the right-hand side blank). So productions are of the form:
where 
is the Kleene star operator, and 
denotes set union.
The other types of formal grammar in the Chomsky hierarchy impose additional restrictions on what constitutes a production. Notably in a context-free grammar, the left-hand side of a production must be a single nonterminal symbol. So productions are of the form:
Record producer
A record producer (or music producer) has a very broad role in overseeing and managing the recording (i.e. "production") of a band or performer's music. A producer has many roles that may include, but are not limited to, gathering ideas for the project, selecting songs and/or session musicians, proposing changes to the song arrangements, coaching the artist and musicians in the studio, controlling the recording sessions, and supervising the entire process through audio mixing (recorded music) and, in some cases, to the audio mastering stage. Producers also often take on a wider entrepreneurial role, with responsibility for the budget, schedules, contracts, and negotiations.
In the 2010s, the recording industry has two kinds of producers with different roles: executive producer and music producer. Executive producers oversee project finances while music producers oversee the creation of music.
A music producer can, in some cases, be compared to a film director, with noted practitioner Phil Ek describing his role as "the person who creatively guides or directs the process of making a record, like a director would a movie. The audio engineering [person] would be more the cameraman of the movie." Indeed, in Bollywood music, the designation actually is music director. The music producer's job is to create, shape, and mold a piece of music. The scope of responsibility may be one or two songs or an artist's entire album – in which case the producer will typically develop an overall vision for the album and how the various songs may interrelate.
Chuggington
Chuggington is a British children's computer-animated television series produced by Ludorum plc. It is broadcast on the BBC children's channel CBeebies and other channels internationally, including in the United States on the Disney Channel and Disney Junior.
Setting
In the fictional town of Chuggington are young novice railway anthropomorphic locomotives ('trainees') Koko, Wilson, Brewster, Hoot, Toot and Piper. The trainees learn the value of loyal friendship, telling the truth, listening carefully, persisting under adversity, completing tasks, resolving conflict without violence, and similar values. The locomotives, called "Chuggers", are intelligent, empathetic, independent and somewhat self-directed. They have mobile facial and body features. Chuggers have no crews (yet some have opening crew doors). Chuggers regularly interact with other humans such as passengers and maintenance crews.
The town of Chuggington has a central area of large modern buildings. Side-by-side railway tunnels coloured red, blue, yellow, green under the town centre lead to the outside world. Countryside settings include a farm, a safari park, and a quarry. A ‘Chugston Hotel’ is mentioned. "Old Chuggington", an abandoned old town overgrown with wild vegetation, is visited. The background and scenery are also computer-generated. There are turning-camera and moving-camera shots.
