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.

Library for Boolean Functions in Algebraic Normal Form
Vasilišin, Maroš ; Mrázek, Vojtěch (referee) ; Dobai, Roland (advisor)
This bachelor thesis focuses on design and implementation of library in C language for manipulation od Boolean functions in Algebraic Normal Form. Majority of existing libraries for representation of Boolean functions is based on binary decision diagrams. Algebraic Normal Form presents several advantages over binary decision diagrams, for example Boolean value of function can be determined in linear time. Implemented library uses simple structures to effectively represent Boolean function in program. After experiments we determined that representation in Algebraic Normal Form has its applications, and in some cases it provides better results than representation in binary decision diagrams.
