Actor Model Middle History - Proving Properties of Actor Systems

Proving Properties of Actor Systems

Carl Hewitt published the principle of Actor induction which is:

  1. Suppose that an Actor x has property P when it is created
  2. Further suppose that if x has property P when it processes a message, then it has property P when it processes the next message.
  3. Then x always has the property P.

In his doctoral dissertation, Aki Yonezawa developed further techniques for proving properties of Actor systems including those that make use of migration. Russ Atkinson and Carl Hewitt developed techniques for proving properties of Serializers that are guardians of shared resources. Gerry Barber's doctoral disseration concerned reasoning about change in knowledgeable office systems.

Famous quotes containing the words proving, properties, actor and/or systems:

    Anyone who seeks for the true causes of miracles, and strives to understand natural phenomena as an intelligent being, and not to gaze at them like a fool, is set down and denounced as an impious heretic by those, whom the masses adore as the interpreters of nature and the gods. Such persons know that, with the removal of ignorance, the wonder which forms their only available means for proving and preserving their authority would vanish also.
    Baruch (Benedict)

    A drop of water has the properties of the sea, but cannot exhibit a storm. There is beauty of a concert, as well as of a flute; strength of a host, as well as of a hero.
    Ralph Waldo Emerson (1803–1882)

    Mr. [John] Barrymore’s smile was the smile of an actor who hates actors, and who knows that he is going to kill two or three before the play is over. I am not an actor-killer, but I like my Hamlets to dislike actors, if you know what I mean, and I think you don’t.
    Robert Benchley (1889–1945)

    Before anything else, we need a new age of Enlightenment. Our present political systems must relinquish their claims on truth, justice and freedom and have to replace them with the search for truth, justice, freedom and reason.
    Friedrich Dürrenmatt (1921–1990)
