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)

    “The actor should not play a part. Like the Aeolian harps that used to be hung in the trees to be played only by the breeze, the actor should be an instrument played upon by the character he depicts.”
    —Alla Nazimova (1879–1945)

    “I am beginning to suspect all elaborate and special systems of education. They seem to me to be built up on the supposition that every child is a kind of idiot who must be taught to think.”
    —Anne Sullivan (1866–1936)
