Essential Features
While the variety of existing process calculi is very large (including variants that incorporate stochastic behaviour, timing information, and specializations for studying molecular interactions), there are several features that all process calculi have in common:
- Representing interactions between independent processes as communication (message-passing), rather than as the modification of shared variables
- Describing processes and systems using a small collection of primitives, and operators for combining those primitives
- Defining algebraic laws for the process operators, which allow process expressions to be manipulated using equational reasoning

Famous quotes containing the words essential and/or features:
“Being so wrong about her makes me wonder now how often I am utterly wrong about myself. And how wrong she might have been about her mother, how wrong he might have been about his father, how much of family life is a vast web of misunderstandings, a tinted and touched-up family portrait, an accurate representation of fact that leaves out only the essential truth.”
—Anna Quindlen (b. 1952)
“Art is the child of Nature; yes,
Her darling child, in whom we trace
The features of the mother’s face,
Her aspect and her attitude.”
—Henry Wadsworth Longfellow (1807–1882)
