Ambient calculus is a form of notation devised by Luca Cardelli and Andrew D. Gordon is Co-designer of Spi Calculus (with M. Abadi), Ambient calculus (Luca Cardelli), and other various programming languages. Until 1997 he was a Research Fellow at the University of Cambridge Computer Laboratory, after which he became Senior Researcher in Programming Principles and Tools for Microsoft. External links... Andrew D. Gordon in 1998 is a common year starting on Thursday of the Gregorian calendar, and was designated the International Year of the Ocean.

Some more general categories that the calculus belongs to (or related with) are: In the first half of the 20th century, various formalisms were proposed to capture the informal concept of computable function, μ-recursive functions, Turing Machines and the λ-calculus possibly being the most well-known examples today. The surprising fact that they are essentially equivalent in the sense that they... process calculi, process algebra, An alternate rewrite has been has been proposed. Please refer to it for large rewrites. A programming language or computer language is a standardized communication technique for expressing instructions to a computer. It is a set of syntactic and semantic rules used to define computer programs. A language enables a... programming language, Computer science (informally, CS or compsci) is, in its most general sense, the study of computation and information processing, both in hardware and in software. Introduction Computer science encomposses a variety of topics relating to computation, ranging from abstract analysis of algorithms and formal grammars, to subjects like programming languages... theoretical computer science, The lambda calculus is a formal system designed to investigate function definition, function application, and recursion. It was introduced by Alonzo Church and Stephen Cole Kleene in the 1930s; Church used the lambda calculus in 1936 to give a negative answer to the Entscheidungsproblem. The calculus can be used to... lambda calculus, At the broadest level, type theory is the branch of mathematics and logic that concerns itself with classifying entities into sets called types. In this sense, it is related to the metaphysical notion of type. Modern type theory was invented partly in response to Russells paradox, and features prominently... type theory.

The three basic ambient primitives, namely in, out, and open are expressive enough to simulate name-passing channels in the 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). Contents // See also Calculus of Communicating Systems Communicating sequential processes Calculus of Broadcasting Systems... pi-calculus. On the other hand, the synchronous nature of the three actions is a difficulty in adopting this model as the programming language core for mobile and distributed computing.
