Sequential and Parallel Grammars: Properties and Applications
Klobučníková, Dominika ; Martiško, Jakub (referee) ; Meduna, Alexandr (advisor)
This thesis deals with the topic of sequential and parallel grammars. Both of these groups cover a large number of grammar families, most of which, however, are not widely used because of the difficulties related to their processing. The thesis examines some of these grammar types, such as scattered-context grammars, multigenerative systems, and interactive L-systems, with focus on their normal forms. Subsequently, it introduces a set of algorithms utilising properties of the discussed grammar types as well as their normal forms. These algorithms are based on the Cocke-Younger-Kasami algorithm for context-free grammars, and are capable of parsing any grammar in the corresponding normal form. Finally, a program implementing the proposed algorithms is presented.

General Grammars: Normal Forms with Applications
Klobučníková, Dominika ; Krčmář, Radim (referee) ; Meduna, Alexandr (advisor)
This thesis deals with the topic of unrestricted grammars, normal forms, and their applications. It focuses on context-sensitive grammars as their special cases. Based on the analysis of the set, an algorithm was designed using the principles of the Cocke-Younger-Kasami algorithm to make a decision of whether an input string is a sentence of a context-sensitivegrammar. The final application, which implements this algorithm, works with context-sensitive grammars in the Penttonen normal form.
