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:
“Cultivate the habit of thinking ahead, and of anticipating the necessary and immediate consequences of all your actions.... Likewise in your pleasures, ask yourself what such and such an amusement leads to, as it is essential to have an objective in everything you do. Any pastime that contributes nothing to bodily strength or to mental alertness is a totally ridiculous, not to say, idiotic, pleasure.”
—Philip Dormer Stanhope, 4th Earl Chesterfield (16941773)
“These, then, will be some of the features of democracy ... it will be, in all likelihood, an agreeable, lawless, particolored commonwealth, dealing with all alike on a footing of equality, whether they be really equal or not.”
—Plato (c. 427347 B.C.)
