A significant challenge in developing concurrent systems is the problem of composability. We create a solution that works properly in isolation, but when composed with other solutions leads to interference. The actor model ensures that individual actors may be composed without changing their behavior. Interference is prevented by definition, keeping the system consistent. In order […]

The Actor Model of Computation, as defined by Carl Hewitt [1] and elaborated by Gul Agha [2], defines three primitive operations. These operations are “Send”, “Create” and “Become”. The “Send” operation transmits an asynchronous message to a known receiver. The “Create” operation constructs a new actor with a specified initial behavior. The “Become” operation defines […]
