Symbol expression
在computer science、mathematics中 ,symbol expression是一种非常有效的、广泛采用的描述方式/语言,本章将对它进行专门描述。
wanweibaike S-expression
In computer programming, S-expressions (or symbolic expressions, abbreviated as sexprs) are a notation for nested list (tree-structured) data, invented for and popularized by the programming language Lisp, which uses them for source code as well as data.
NOTE:
一、"expression tree and 括号-Nested parentheses"
二、关于S-expression的一些非常好的例子,参见:
a、cs.unm 11 S-expressions, the Syntax of Lisp
Symbol expression in computer science
1、在computer science中,使用symbol expression来描述abstract structure(这其实是一次抽象过程),然后依据此structure来生成computation。比如formal language、computational graph。理解语义。
2、本文是在computer algebra、formal language之上的,以一个更高的角度来描述它们,或者说,它们都可以看做是symbol的一种application 。
Symbol expression and tree
1、在computer science中,symbol expression 都可以使用tree、graph来进行描述、实现。
2、expression tree
