Mobile robot path planning by means of cellular automata
Holoubek, Tomáš ; Šoustek, Petr (referee) ; Dvořák, Jiří (advisor)
This thesis deals with a path planning using cellular automata algorithms in a rectangular grid environment. Theoretical part starts with an overview of commonly used approaches for path planning and later on focuses on existing cellular automata solutions and capabilities in detail. Implemented cellular automata algorithms and the commonly used path planning algorithms are together with a map generator described in the practical part. Conclusion of this thesis contains results completed in a special application.

Sorting algorithms
Schwarz, Jakub ; Smrž, Jaroslav (referee) ; Dvořák, Jiří (advisor)
Enormous volume of data, which has been processed during production operations, requires easy orientation and quick searching. Exact search in real time is essential for success. Correct and quick data-sorting is one of the most important activity during dataprocessing. The goal of this bachelor’s thesis is background research of sorting algorithms. To achieve the goal, basic concepts of sorting theory will be described (determined) and there will be division of sorting algorithms by different criterions. For each algorithm of internal array sorting, sorting principles will be described and analysis of efficiency will be provided. The results will be verified by experimental program.

Production planning under uncertainty
Grulich, Martin ; Popela, Pavel (referee) ; Dvořák, Jiří (advisor)
This diploma work deals with a dynamic multi-level multi-item lot sizing problem in a general production-assembly structure represented by a directed acyclic network, where each node may have several predecessors and successors. We assume stochastic demand, finite planning horizon consisting of discrete time periods, dynamic lot sizes, multiple constrained resources and time-varying cost parameters. The objective is to minimize the total costs over the planning horizon. This thesis includes overview of models with stochastic demand and also general description of genetic algorithm. Using different modifications of genetic algorithm I have proposed and implemented methods for solving a chosen model. Then I have made an experimental comparison of these method on selected problems.
