Calculus of Broadcasting Systems (CBS) is a CCS-like calculus where processes speak one at a time and are heard instantaneously by all others. Speech is autonomous, contention between speakers being resolved nondeterministically, but hearing only happens when someone else speaks. Observationally meaningful laws differ from those of CCS. The handshake communication of CCS is changed to broadcast communication in CBS. This allows several additional features: The Calculus of Communicating Systems (or CCS) (one of the first process calculi) was developed by Robin Milner. ... Integral and differential calculus is a central branch of mathematics, developed from algebra and geometry. ... Look up Process in Wiktionary, the free dictionary Process (lat. ... This article is about the general notion of determinism in philosophy. ...
Priority, which attaches only to autonomous actions, is simply added to CBS in contrast to CCS, where such actions are the result of communication.
A CBS simulator runs a process by returning a list of values it broadcasts. This permits a powerful combination, CBS with the host language. It yields several elegant algorithms. Only processes with a unique response to each input are needed in practice, so weak bisimulation is a congruence.
CBS subsystems are interfaced by translators; by mapping messages to silence, these can restrict hearing and hide speech. Reversing a translator turns its scope inside out. This permits a new specification for a communication link – the environment of each user should behave like the other user.
In theoretical computer science, the π-calculus is a notation originally developed by Robin Milner, Joachim Parrow and David Walker to model concurrency (just as the λ-calculus is a simple model of sequential programming languages). ... The Calculus of Communicating Systems (or CCS) (one of the first process calculi) was developed by Robin Milner. ... In computer science, Communicating Sequential Processes (CSP) is a formal language for describing patterns of interaction in concurrent systems. ... In theoretical computer science a bisimulation is an equivalence relation between state transition systems, associating systems which behave in the same way in the sense that one system simulates the other and vice-versa. ... Alternating bit protocol (ABP) means a simple data link layer network protocol that retransmits lost or corrupted messages. ...

The systems of basic physics were amenable to this process, as they can be studied as systems with few simple components, subject to a restricted set of external inputs.
The constraints imposed on the study of the behavior of dynamical systems by the restriction to analytical methods, and the study of the behavior of collective systems using statistical methods, can be relaxed by the use of fast computation.
This topic introduces some literature focused on studies of environmental systems, systems including both the collective dynamics of human systems as well as the ecological systems in which these social systems are embedded.
