Využití operačního výzkumu při navrhování linek v městské hromadné dopravě / Application of Operations Research in Line Planning in Urban Public TransportFator, Jiří January 2011 (has links)
This diploma thesis analyzes the problem of line planning in urban public transport as an object of Operations Research. It is based on the Theory of Graphs, building specific model network referring to a real existing network. Each line represents the flow through part of this network, respecting additional constraints. The goal is to optimize existing routing by decreasing the number of lines in service and making the routing easier to understand and remember. On the contrary to casual models, this one has been designed to perfectly describe a real existing network, tramway service in Prague, Czech Republic. Furthermore, no set of lines is given in advance. The flow is newly computed by optimizing software to fit the demand and the capacity of each branch. So the output should give the user a concrete route of each line in operation.

Využití genetického programování při tvorbě obchodní strategie na devizovém trhu / The use of genetic programming in forex trading strategy developmentLíbal, Petr January 2011 (has links)
This thesis deals with trading strategy development on foreign market exchange (FOREX) from a perspective of technical analysis. A hypothesis that price data can be used for stable profitable decision making is analyzed. For that purpose, financial data preparation and derived indicators are described in detail. At first, strategies are randomly constructed. Afterward, they are improved iteratively by means of evolution principles. Genetic programming is used in particular. Special attention is devoted to fitness functon definition, on which the progress of strategies depends. Besides usual criterion - profit, other aspects are taken into account. Transactional costs are included in strategy evaluation. Costs have even been increased in comparison with declared values. Some of the best strategies are tested on data, which has not been used for their development. Obtained results did not support the hypothesis. However, process of a strategy search can be improved.

Využití umělých neuronových sítí k řízení genetických algoritmů / Using artificial neural networks to control genetic algorithmsDörfler, Martin January 2012 (has links)
Genetic algorithms are some of the most flexible among optimization methods. Because of their low requirements on input data, they are able to solve a wide array of problems. The flexibility is balanced by their lower effectiveness. When compared to more specialized methods, their results are inferior. This thesis examines the possibility of increasing their effectiveness by means of controlling their run by an artificial neural network. Presented inside are means of controlling a run of a genetic algorithm by a self-organizing map. The thesis contains an algorithm proposal, a prototype implementation of such algorithm and a series of tests to assess its efficiency. While the results on benchmark functions show some positive properties, the problems of greater complexity yield less optimistic results.

IMAP extension for mobile devices / IMAP extension for mobile devicesKundrát, Jan January 2012 (has links)
With the mass availability of smartphones, mobile access to e-mail is gaining importance. Over the years, the IMAP protocol has been extended with many features ranging from extensions adding new functionality to those improving efficiency over an unreliable network. This thesis evaluates the available extensions based on their suitability for use in the context of a mobile client. Three new extensions have been developed, each improving the protocol in a distinct way. The thesis also discusses how most of these extensions were implemented in Trojitá, the author's free software open source IMAP e-mail client.

Stromová šířka, rozšířené formulace CSP a MSO polytopů a jejich algoritmické aplikace / Treewidth, Extended Formulations of CSP and MSO Polytopes, and their Algorithmic ApplicationsKoutecký, Martin January 2017 (has links)
In the present thesis we provide compact extended formulations for a wide range of polytopes associated with the constraint satisfaction problem (CSP), monadic second order logic (MSO) on graphs, and extensions of MSO, when the given instances have bounded treewidth. We show that our extended formulations have additional useful properties, and we uncover connections between MSO and CSP. We conclude that a combination of the MSO logic, CSP and geometry provides an extensible framework for the design of compact extended formulations and parameterized algorithms for graphs of bounded treewidth. Putting our framework to use, we settle the parameterized complexity landscape for various extensions of MSO when parameterized by two important graph width parameters, namely treewidth and neighborhood diversity. We discover that the (non)linearity of the MSO extension determines the difference between fixedparameter tractability and intractability when parameterized by neighborhood diversity. Finally, we study shifted combinatorial optimization, a new nonlinear optimization framework generalizing standard combinatorial optimization, and provide initial findings from the perspective of parameterized complexity
