New Parallel and Regulated Automata and Grammars
Kučera, Jiří ; Průša, Daniel (referee) ; Sawa, Zdeněk (referee) ; Meduna, Alexandr (advisor)
Tato práce zkoumá a zavádí čtyři nové jazykové modely se zaměřením na regulované a paralelní verze automatů a gramatik. První z modelů, stavově synchronizované systémy automatů , zavádí systémy složené z konečného počtu zásobníkových automatů jejichž činnost je řízena slovy z řídícího jazyka nad množinou stavů. Druhý model, neomezené hluboké zásobníkové automaty , je variantou hlubokých zásobníkových automatů z nichž bylo sejmuto omezení kladené na hloubku expanze na zásobníku. Třetí model, skákající čisté gramatiky , zavádí skákající gramatiky bez neterminálních symbolů. Poslední model, k#$-přepisující systémy , rozšiřuje #-přepisující systémy o přídavnou zásobníkovou paměť. Text této práce je členěn do tří částí. První část uvádí motivaci k zavedení studovaných jazykových modelů a zasazuje je do kontextu souvisejících oblastí teorie formálních jazyků. Je zde také uveden přehled o celkové organizaci práce, základních pojmů teorie formálních jazyků a současných poznatků souvisejících s předmětem výzkumu. Druhá část tvoří jádro této práce. Jsou v ní formálně definovány všechny nově zavedené jazykové modely a studována jejich vyjadřovací síla. Poslední část uzavírá tuto práci souhrnem získaných teoretických výsledků společně se souvisejícími otevřenými problémy a nastiňuje cesty dalšího výzkumu spolu s výhledy na možná využití.
New Structures and Operations in Mathematical Informatics
Bureš, Richard ; Krčmář, Radim (referee) ; Meduna, Alexandr (advisor)
The aim of this thesis is to look at some known and some in this thesis created operati- ons and their properties mainly over the regular, but also over the context-free languages. Further we will focus on how to "carry out" these operations over finite and pushdown auto- mata and finally we will present how to possibly impement these automata and operations over them.
Tool for Abstract Regular Model Checking
Chalk, Matěj ; Rogalewicz, Adam (referee) ; Hruška, Martin (advisor)
Formal verification methods offer a large potential to provide automated software correctness checking (based on sound mathematical roots), which is of vital importance. One such technique is abstract regular model checking, which encodes sets of reachable configurations and one-step transitions between them using finite automata and transducers, respectively. Though this method addresses problems that are undecidable in general, it facilitates termination in many practical cases, while also significantly reducing the state space explosion problem. This is achieved by accelerating the computation of reachability sets using incrementally refinable abstractions, while eliminating spurious counterexamples caused by overapproximation using a counterexample-guided abstraction refinement technique. The aim of this thesis is to create a well designed tool for abstract regular model checking, which has so far only been implemented in prototypes. The new tool will model systems using symbolic automata and transducers instead of their (less concise) classic alternatives.
Game for Oculus Quest
Kryštůfek, Jakub ; Novák, Jiří (referee) ; Pomikálek, Jiří (advisor)
The aim of this bachelor thesis is to create a prototype of a videogame in virtual reality for target platform Oculus Quest 2. The game was created with game engine Unity with emphasis on optimalization and extensibility of implemented systems. Within the implemented game was created system of autonomous agents via finite state machines and planning architecture goal-oriented action planning. One of the most insteresting game mechanics is fire propagation system implemented with cellular automaton.
Classification and Usage of Languages, Grammars and Machines
Jancek, Libor ; Novotná, Veronika (referee) ; Bobalová, Martina (advisor)
This bachelor thesis is focused on theory of languages, grammars and automats, on showing real examples of linale machine and on creating program for firm "Paradise Casino Admiral a.s.". Purpose of mentioned program is to ease and speed up the work of department manager by tracking of employee attendance from preset workshift schedule
Parsing Based on State Grammars
Svatý, Lukáš ; Vrábel, Lukáš (referee) ; Solár, Peter (advisor)
Syntax-directed translation based on state grammars is introduced in this bachelor's thesis. Theoretical section of this thesis is focused on the introduction of theoretical models that are necessary for understanding syntax analysis based on state grammars. The most important theoretical formal models in this thesis include deep pushdown transducer and translation grammar based on state grammar, which can be used in syntax analysis. Practical section of this thesis is focused on bottom-up syntax analysis using state grammar and its implementation.
Modified Deep Pushdown Automata
Škvařilová, Radka ; Horáček, Petr (referee) ; Meduna, Alexandr (advisor)
This thesis introduce two new modifications of deep pushdown automata - stateless deep pushdown automata and parallel deep pushdown automata. In theoretical part of this thesis is formal definition and research into power of these modification. Practical part consists of an implementation of simple automata program.
Demonstration Program of Simulation of Pushdown Automata
Kuželová, Ludmila ; Koutný, Jiří (referee) ; Lukáš, Roman (advisor)
The thesis deals with working simulation of stack and extended automata. Part of the work is a demonstration application, enabling the user to enter a configuration of automaton and start simulating the proccess of accepting a input sequence. Chosen is a fitting method of searching a state space, using the Breadth First Search method.
Parallel Deep Pushdown Automata
Solár, Peter ; Křivka, Zbyněk (referee) ; Meduna, Alexandr (advisor)
This thesis introduces parallel deep pushdown automata as the parallel version of the deep pushdown automata. They are based on the rules, where the automaton can expand n topmost non-terminals in only one derivation step if there are enough non-terminals on the pushdown. The main advantage rests in a fact, that parallel automaton can makde a decission faster.
Mathematical and Statistical Methods as Support of the Development of Software Applications
Ježek, Jan ; Šustrová, Tereza (referee) ; Novotná, Veronika (advisor)
The aim of this thesis is to apply selected statistical methods with the objective of optimizing the calculation of profitability of vending machines and snack machines based on the data collected during restocking. The thesis includes the development of an algorithm for analyzing the restocking time and the time required to move between machines, with a focus on identifying suspicious behavior.
