Parsing of Regulated Grammars
Šrajer, Roman ; Čermák, Martin (referee) ; Křivka, Zbyněk (advisor)
This thesis studies regulated grammars, their fundamentals and expressing power regarding Chomsky hierarchy of languages. Programmed grammars are investigated in more depth considering a few types of leftmost derivations. A variant of deterministic syntax analysis of programmed grammars is introduced. This analysis works similarly as LL(k) parsing. Transformations of matrix grammars into programmed grammars without changing their expressing power are introduced. The syntax analysis by regularly controlled grammars partly using programmed grammars are presented. In the end, cooperating distributed grammars with left permitting grammars as components are mentioned. Their deterministic syntax analysis uses predictive table or exhaustive exploration of the whole state space.

Demonstration of Tree Controlled Grammars Properties
Kunštátský, Martin ; Čermák, Martin (referee) ; Koutný, Jiří (advisor)
Tree controlled grammars are grammars regulated by restriction placed on its derivation trees. It is simple and natural extension of context-free grammars. There are several types of derivation tree control, two principles are mentioned in this work: horizontal and vertical control. Application demonstrating tree controlled grammars properties, implemented in Python programming language, is also part of this work.
