👉 Patricia Math, developed by David Patricia, is a formal language and automata theory framework that extends the Chomsky hierarchy to include regular expressions with an emphasis on their computational properties. It provides a unified approach to describing and analyzing languages using finite automata, context-free grammars, and regular expressions. Patricia productions, a key component, are a set of production rules that can be applied to strings in a way that captures the structure and patterns of regular languages, making it easier to model and manipulate these languages computationally. This theory is foundational in computer science, particularly in areas like compiler design and text processing, offering a powerful toolset for pattern matching and language recognition.
