Formal Systems
Over the years, several different formal systems have been developed which permit reasoning about systems in the Actor model. These include:
- Operational semantics
- Laws for Actor systems
- Denotational semantics
- Transition semantics
There are also formalisms that are not fully faithful to the Actor model in that they do not formalize the guaranteed delivery of messages including the following (See Attempts to relate Actor semantics to algebra and linear logic):
- Several different Actor algebras
- Linear logic

Famous quotes containing the words formal and/or systems:
“That anger can be expressed through words and non-destructive activities; that promises are intended to be kept; that cleanliness and good eating habits are aspects of self-esteem; that compassion is an attribute to be prized—all these lessons are ones children can learn far more readily through the living example of their parents than they ever can through formal instruction.”
—Fred Rogers (20th century)
“The only people who treasure systems are those whom the whole truth evades, who want to catch it by the tail. A system is just like truth’s tail, but the truth is like a lizard. It will leave the tail in your hand and escape; it knows that it will soon grow another tail.”
—Ivan Sergeevich Turgenev (1818–1883)
