A marked graph is a Petri net in which every place has exactly one incoming arc, and exactly one outgoing arc. This means, that there can not be conflict, but there can be concurrency. Mathematically: . Marked graphs are used mostly to mathematically represent concurrently running operations, such as a multiprocessor machine's internal process state.
Famous quotes containing the words marked and/or graph:
“... [Washington] is always an entertaining spectacle. Look at it now. The present President has the name of Roosevelt, marked facial resemblance to Wilson, and no perceptible aversion, to say the least, to many of the policies of Bryan. The New Deal, which at times seems more like a pack of cards thrown helter skelter, some face up, some face down, and then snatched in a free-for-all by the players, than it does like a regular deal, is going on before our interested, if puzzled eyes.”
—Alice Roosevelt Longworth (1884–1980)
“In this Journal, my pen is a delicate needle point, tracing out a graph of temperament so as to show its daily fluctuations: grave and gay, up and down, lamentation and revelry, self-love and self-disgust. You get here all my thoughts and opinions, always irresponsible and often contradictory or mutually exclusive, all my moods and vapours, all the varying reactions to environment of this jelly which is I.”
—W.N.P. Barbellion (1889–1919)
