Formal languages and classes of automata. Inherently difficult combinatorial problems. CS 622 Theory of Formal Languages. This course treats languages from an abstract point of view as defined by formal grammars and by families of abstract machines. The Chomsky hierarchy and associated automata are covered.
Emphasis is placed on context free languages.
Careful mathematical definition and proof is stressed throughout. This course does not involve programming. This course is of special interest to students interested in linguistics and in the theory of programming language compilers. CS 624 Analysis of Algorithms. Applications to searching and sorting algorithms.
