Concurrent Pattern Calculus

چکیده
Concurrent pattern calculus drives interaction between processes by unifying patterns, just as sequential pattern calculus drives computation by matching a pattern against a data structure. By generalising from pattern matching to unification, interaction becomes symmetrical, with information flowing in both directions. This provides a natural language for describing any form of exchange or trade. Many popular process calculi can be encoded in concurrent pattern calculus.

A Concurrent Pattern Calculus
Concurrent pattern calculus (CPC) drives interaction between processes by comparing data structures, just as sequential pattern calculus drives computation. By generalising from pattern matching to pattern unification, interaction becomes symmetrical, with information flowing in both directions. CPC provides a natural language to express trade where information exchange is pivotal to interactio...
متن کاملA Typed Calculus for Querying Distributed XML Documents
We study the problems related to querying large, distributed XML documents. Our proposal takes the form of a new process calculus in which XML data are processes that can be queried by means of concurrent pattern-matching expressions. What we achieve is a functional, strongly-typed programming model based on three main ingredients: an asynchronous process calculus that draws features from π-cal...
متن کاملExpressiveness via Intensionality and Concurrency
Computation can be considered by taking into account two dimensions: extensional versus intensional, and sequential versus concurrent. Traditionally sequential extensional computation can be captured by the λ-calculus. However, recent work shows that there are more expressive intensional calculi such as S F-calculus. Traditionally process calculi capture computation by encoding the λ-calculus, ...
متن کاملAn Intensional Concurrent Faithful Encoding of Turing Machines
The benchmark for computation is typically given as Turing computability; the ability for a computation to be performed by a Turing Machine. Many languages exploit (indirect) encodings of Turing Machines to demonstrate their ability to support arbitrary computation. However, these encodings are usually by simulating the entire Turing Machine within the language, or by encoding a language that d...
متن کاملPattern Matching and Bisimulation
Concurrent Pattern Calculus (CPC) is a minimal calculus whose communication mechanism is based on a powerful form of symmetric pattern unification. However, the richness of patterns and their unification entails some flexibility in the challenge-reply game that underpins bisimulation. This leads to an ordering upon patterns that is used to define the valid replies to a given challenge. Such a t...
