Cellular Automaton in Evolutionary Process
Hejč, Michal ; Herrman, Tomáš (referee) ; Bidlo, Michal (advisor)
The aim of this master's theses it to focuse on the usage of genetic algorithms in combination with a technique of biologically inspired development in cellular automata. The principles of the proposed method is described. The main part of this work deals with the design of combinational logic circuits. The genetic algorithm is utilized to design a nonuniform one-dimensional cellular automaton (in particular, the local transition functions) which serves as a circuit generator. Experiments have been conducted to design of basic types of combinational circuits and polymorphic circuits. Finally, the results are presented and compared with the results obtained in the previous work in which a uniform cellular automaton was applied.

A Nanocomputer Simulator Using Cellular Automaton
Kmeť, Dušan ; Bidlo, Michal (referee) ; Sekanina, Lukáš (advisor)
This master thesis deals with the realization of a simulator based on asynchronous cellular automata simulating delay insensitive circuits. In connection with nanotechnology, cellular automata have several interesting properties, such as self-replication, regular structure and high parallelism that make them very useful as models for some types of nanocomputers. This text describes the relationship between cellular automata and nanotechnology. Emphasis is given to the possibility of using asynchronous timing mode. Asynchronous cellular arrays based on asynchronous cellular automata could prove to be a suitable architecture for future nanocomputer, which was the reason for implementation of this simulator. The simulator's functionality was verified by experiments.

Description of traffic flow characteristics
Novák, Martin ; Holcner, Petr (referee) ; Apeltauer, Tomáš (advisor)
The aim of this thesis is to observe behavior of traffic flow and to verify or refute traditional so called fundamental relationships. It analyze data based on older measurements, personal measurements executed on the I/43 road, and mathematical models.There were three tools used provided by "VUT" in Brno as well as own developed tool based on cellular automat..

Optimization Using Ant Algorithms
Válek, Matěj ; Drábek, Vladimír (referee) ; Bidlo, Michal (advisor)
This bachelor thesis will deal with various applications of ant colony optimisation. In particular, Ant Colony System will be applied on the optimisation of traveling salesman problem and the design of rules for the development of cellular automata. The obtained results will be statistically analysed. Moreover, a GUI-based application has been developed which allows to interactively observe the progress of Ant Colony System for the educational purposes.

Quantum-Inspired Optimisation Algorithms
Kosík, Dominik ; Sekanina, Lukáš (referee) ; Bidlo, Michal (advisor)
The focus of this work is an implementation of the chosen quantum-inspired optimisation algorithm and its modifications, which will be compared at the end of the work. As the optimisation algorithm was chosen simulated quantum annealing algorithm. The first part of the work will lay the theoretical groundwork of standard optimisation algorithms used in this work, physics from which the inspiration for the simulated quantum annealing originates, and a description of the chosen algorithm. The second part will focus on the implementation of the algorithms on the selected problems. The selected problems are travelling salesman problem, searching rules for cellular automaton and MAX-SAT problem. The last part will contain the proposed modifications of the simulated quantum annealing, a comparison of the basic variant and standard optimisations algorithms, and an evaluation of the results.

Music Creation Using Cellular Automata
Novotný, Pavel ; Martinek, David (referee) ; Peringer, Petr (advisor)
In this thesis the cellular automata are used for algorithmic music composition. It contains a general overview of the algorithmic composition method and cellular automata. The crucial part of the thesis describes the concept and implementation of the program with a graphical user interface which uses two simple methods for conversion cellular automata's states into music. The final program was tested on several cellular automata and the sound outputs of both methods were compared with each other. The program is useful especially for the creation of short melodies.

Evolutionary Design of Simulator Based on Cellular Automata
Brigant, Vladimír ; Šperka, Svatopluk (referee) ; Mrnuštík, Michal (advisor)
This work describes concept of a cellular automata (CA) simulator, which is able to predict behaviour of a complex spatial system. This prediction is based on available training data and transition rule acquired from regression analysis powered by evolutionary algorithms. Two regression analysis methods (linear and logistic regression) are suggested, implemented and compared on urban growth prediction of Brno city.

GUI for Microscopic Traffic Simulation
Fülöp, Tibor ; Petrlík, Jiří (referee) ; Korček, Pavol (advisor)
Nowadays the road traffic is more complex and number of vehicles increases. The goal of this thesis is to develop microscopic traffic simulator with graphical user interface which it is possible to experiment with. The simulator can be used to construction of road topology with multiple lane roads and crossroads. It supports creating uncontrolled crossroads, crossroads with main road or crossroad with traffic lights. It generates and shows macroscopic data during simulation. It is based on cellular automaton and model is inspired by Nagel-Schreckenberg traffic model. There are results of simulating simple traffic simulations in the thesis.

Evolution of Emergent Behavior in Cellular Systems
Novák, Radim ; Žaloudek, Luděk (referee) ; Bidlo, Michal (advisor)
This master's thesis deals with the topic of cellular automata and their utilization in the research of self-replication, especially with the focus on self-replicating loops. It also shows several possible approaches how to optimize the replication process. The first part is focused on theoretical aspects of cellular automata. It acquaints the readers with the questions of self-replication in the cellular automata and present some of the existing self-replicating loops, starting with the widely known Langton's loop. The second part presents the optimization of the replication process considering two selected variants of self-repricating loops - Byl's loop and Chou-Reggia loop. Two approaches are introduced together with their possible combination. The first approach is based on multiple self-replication. The second one is based on the reduction of the number of steps of the cellular automaton needed to create a copy of the loop.
