Wang Tiles for Frequency-Based Synthesis of Ocean Surfaces
Vámošová, Mária ; Wilkie, Alexander (advisor) ; Krajíček, Václav (referee)
Frequency-based ocean synthesis is a class of methods for generating ocean waves in deep water using physically based ocean spectra provided by oceanographic research. The output of these methods is a heightfield which is periodic and can be used to tile a larger area. However, when using a larger number of tiles, a repetition pattern becomes apparent. Wang tiling is a method of tiling the plane non- periodically by using only a small set of input tiles with given constraints. The aim of this thesis is to create a set of Wang Tiles, each of which represents an ocean heightfield synthesised by a frequency- based method, so one can create large ocean scenes without apparent periodicity in the tiling pattern.

Barvení grafů pomocí mravenčí kolonie
Vámošová, Mária ; Lidický, Bernard (referee) ; Jelínková, Eva (advisor)
In the present thesis we deal with the Graph Coloring Problem. We provide an overview of the existing approaches and focus on the Ant Colony Optimization heuristics. We have selected three algorithms, implemented them and performed a set of tests on several commonly used graph instances to study their advantages and drawbacks. We also compared their results to the best known at time to nd out how much they are suitable for the problem. In this thesis we also present an original algorithm.
