A Tool for Visual Analysis of Circuit Evolution
Staurovská, Jana ; Minařík, Miloš (referee) ; Sekanina, Lukáš (advisor)
The main goal of the master's thesis is to compose a study on cartesian genetic programming with focus on evolution of circuits and to design a concept for visualisation of this evolution. Another goal is to create a program to visualise the circuit evolution in cartesian genetic programming, its generations and chromosomes. The program is capable of visualising the changes between generations and chromosomes and comparing more chromosomes at once. Several user cases had been prepared for the resulting program.

FPGA Platform with .NET Micro Framework Support
Matyáš, Jan ; Minařík, Miloš (referee) ; Vašíček, Zdeněk (advisor)
The goal of the thesis is to design a development board that may be used for embedded systems prototyping. The board's key parts are an ARM-Cortex-based microcontroller and a FPGA programmable circuit. The platform is designed with .NET Micro Framework support in mind. The thesis contains specifications of the development board, describes the design process as well as the task of .NET Micro Framework porting and the establishment of communication bus between the FPGA and microcontroller circuits. The thesis is concluded by a set of demonstration examples which outline how to develop new applications for the designed platform.

Investigation of Sokoban Game Using Genetic Algorithms
Nezvalová, Leona ; Vašíček, Zdeněk (referee) ; Minařík, Miloš (advisor)
This work proposes an automatic Sokoban solver based on genetic algorithms. Emphasis is placed on the chromosome representation, that helps to deal with main problems related to automatic solving - size of a state space and presence of deadlocks. These problems are also addressed by specialized crossover operation and fitness function. The secondary objective is to optimize the solution using the optimization function and evolution itself.

Creating Timetables Using Genetic Algorithms
Horký, Aleš ; Matoušek, Jiří (referee) ; Minařík, Miloš (advisor)
This bachelor thesis contains design and implementation of two-phase genetic algorithm intended for creating timetable schedules at primary schools. The algorithm is designed for maximum reduction of state space of solved problem without decrease of its universality. The implementated program in C++ language is applicable for creating timetable schedules at small and medium sized schools.

Using Softcomputing Techniques for User Behavior Prediction and Analysis
Šimon, Jakub ; Sopuch, Zbyněk (referee) ; Minařík, Miloš (advisor)
This Bachelor's thesis studies the possibilities of employee's behavior prediction and analysis. It uses softcomputing techniques, two types of neural networks - Multi-layer feedforward neural network with the Backpropagation algorithm, and Kohonen selforganizing map. The experiments performed on real activity records of employees are included. Part of the thesis is focused on activity records data and their characteristics. As a conclusion some basic information about the pros and cons of neural networks' use in the field of employee behavior prediction and analysis is given.

Structural Methods of Objects Identification for Industrial Robot Operation
Minařík, Martin ; Šlapal, Josef (referee) ; Konečný, Vladimír (referee) ; Šťastný, Jiří (advisor)
This PhD thesis deals with the use of structural methods of objects identification for industrial robots operation. First, the present state of knowledge in the field is described, i.e. the whole process of objects recognition with the aid of common methods of the syntactic analysis. The main disadvantage of these methods is that is impossible to recognize objects whose digitalized image is corrupted in some ways (due to excessive noise or image disturbances), objects are therefore deformed. Further, other methods for the recognition of deformed objects are described. These methods use structural description of objects for object recognition, i.e. methods which determine the distance between attribute descriptions of images. The core part of this PhD thesis begins in Chapter 5, where deformation grammars, capable of description of all possible object deformations, are described. The only complication in the analysis is the ambiguity of the deformation grammar, which lowers the effectiveness of the analysis. Further, PhD thesis deals with the selection and modification of a proper parser, which is able to analyze a deformation grammar effectively. Three parsers are described: the modified Earley parser, the modified Tomita parser and the modified hybrid LRE(k) parser. As for the modified Earley’s parser, ways of its effective implementation are described. One of the necessary parts of the object recognition is providing the invariances, which this PhD thesis covers in detail, too. Finally, the results of described algorithms are mentioned (successfulness and speed of deformed objects recognition) and suggested testing environment and implemented algorithms are described. In conclusion, all determined possibilities of deformation grammars and their results are summarized.
