Semi-Thue system - Wikipedia

In theoretical computer science and mathematical logic a string rewriting system (SRS), historically called a semi-Thue system, is a rewriting system over strings from a (usually finite) alphabet. Given a binary relation between fixed strings over the alphabet, called rewrite rules, denoted by , an SRS extends the rewriting relation to all strings in which the left- and right-hand side of the rules appear as substrings, that is , where , , , and are strings. naviswork pro edition

In the present paper, we transfer this result to match-bounded string rewriting. Every match-bounded system terminates, and eﬀectively preserves regularity of lan-guages. Therefore it is decidable whether a given system has a given match-bound.

However, the perfect results are still not guaranteed with manual rewriting, and … WebAn L-System is a string rewriting system that can generate fractal and tree like structures. They consist of a seed string and a set of rules to grow the seed into a more complex string. Each rule operates on a single character of the string, and replaces that character with another string.

String rewriting system

A string rewriting system (SRS), also known as semi-Thue system, exploits the free monoid structure of the strings (words) over an alphabet to extend a rewriting relation, , to all strings in the alphabet that contain left- and respectively right-hand sides of some rules as substrings. Formally a semi-Thue system is a tuple where is a (usually finite) alphabet, and is a binary relation between some (fixed) strings in the alphabet, called the set of rewrite rules.

Webrewriting system R is a finite collection of rewrite rules. String rewriting systems have been extensively studied, see e.g. [BOOK]. Let R be a string rewriting system.
