The I/O automata formalism是什麼?

看不懂原文介紹,請大家幫幫忙,謝謝!

The I/O automata formalism

  In this Appendix we introduce the I/O automata formalism.

We use a slight simplification of the I/O automaton of Lynch and Tuttle, ignoring the aspects related to liveness.

We include only those parts we consider necessary to understand the paper.

For a full discussion, the reader is referred to [8]

  In the I/O automata formalism, all components in a system are modeled by using automata.

An I/O automaton A is composed of:

(1) A set of states, some of which are designated as initial states

(2) A signature of actions, sig(A). Such a signature consists of three mutually disjoint sets of actions: input, in(sig(A)); output, out(sig(A)); and internal, int(sig(A)). We denote the set of external actions of the signature as ext(sig(A)) = in(sig(A)) ∪ out(sig(A))

(3) A transition relation, which is a set of triples of the form (S,π,S'), where S' and S are states, and π an action.

This triple means that in state S, the automaton can atomically do action π and change to state S'

 An element of the transition relation is called a step.

Output actions are intended to model the actions that are triggered by the automaton itself, while input actions model actions that are triggered by the environment of the automaton (an automaton must be prepared to receive any input action at any time)

Internal actions are used to model communication between components within the automaton

Update:

不是要翻譯,

是要知道The I/O automata formalism是什麼?

所列那一大段是原文簡介,雖然看了,還是不懂,所以上來看找人幫忙

[8] N. Lynch, Distributed Algorithms, Morgan Kaufmann Publishers, Inc., Los Altos, CA, 1996.

是那一大段原文簡介的出處,是一本1996年介紹〔分散式演算法〕的書

Update 2:

我目前是資訊科學系的學生,之前是修資管,

但數學中的 automata 我就不清楚了,

不知道我這樣補充夠嗎?

謝謝您的意見!
