Semi-Thue system

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 R {\displaystyle R} between fixed strings over the alphabet, called rewrite rules, denoted by s → t {\displaystyle s\rightarrow t} , an…
