Metody řešení dvouúrovňových optimalizačních úloh / Solving methods for bilevel optimization problemsLžičař, Jiří January 2019 (has links)
The presented thesis discusses bilevel programming problems with the focus on solution algorithms. Bilevel programming problem is a hierarchical programming problem, where constraints contain another programming problem. We formulate basic bilevel optimization theory and describe three types of so- lution algorithms for bilevel programming problems: Algorithms based on KKT reformulation where the lower level is replaced by its KKT conditions, algorithms based on optimal value function where the bilevel programming problem is re- duced to a single level problem using the optimal value function of the lower level problem, and algorithms solving linear bilevel programming problems. Using real data for portfolio optimization bilevel programming problems, we compare ability to solve the problems and computing time of some of the pre- sented algorithms. 1

Logické úlohy a hlavolamy jako optimalizační problémy / Logical puzzles and brainteasers as optimization problemsLukesová, Kristýna January 2011 (has links)
This thesis applies classical optimization problems such as assignment or set-covering problem on logical puzzles or brainteasers. Listed in the first part are mathematical model, description and typical example of each optimization problem used in this thesis. The second part contains these models applied to the particular brainteasers for example Sudoku or Einstein's Puzzle. Exercises are divided into simpler and more complex ones. There is specification, source and a described method of solution stated for each of them. The calculation examples use Lingo or MS Excel or both. The aim is to show the possibility to address logical puzzles and brainteasers with the use of optimization problems, and thus confirm the wide possibilities of using these models. These examples can clarify and diversify the curriculum.

Efektivní techniky pro měření výkonu programů / Efficient Techniques for Program Performance AnalysisPavela, Jiří January 2020 (has links)
Tato práce představuje optimalizační techniky zaměřené na proces sběru výkonnostních dat v rámci výkonnostní analýzy a profilování programů v nástroji Perun. Rozšíření architektury a implementace těchto nových optimalizačních technik v nástroji Perun (a převážně pak v jeho modulu Tracer) zlepšuje jeho škálovatelnost a umožňuje tak provádět výkonnostní analýzu i nad rozsáhlými projekty. Zaměřujeme se především na zvýšení přesnosti sběru dat, redukci množství instrumentovaných bodů programu, omezení časové režie procesu sběru dat a výkonnostního profilování, snížení objemu sbíraných dat a velikosti výsledného výkonnostního profilu. Optimalizace je dosažena pomocí aplikace statistických metod, množství technik statické a dynamické analýzy (případně jejich kombinací) a využitím pokročilých možností a schopností nástrojů SystemTap a eBPF. Na základě vyhodnocení provedeného na dvou vybraných projektech a množství experimentů můžeme konstatovat, že se nám úspěšně podařilo dosáhnout značné optimalizace u téměř všech sledovaných metrik a kritérií.

Termické zpracování odpadů jako klíčový prvek efektivních systémů odpadového hospodářství / EFFECTIVE UTILIZATION OF MUNICIPAL SOLID WASTE IN HEAT AND POWER SYSTEMSPutna, Ondřej January 2020 (has links)
The dissertation thesis is focused on the issue of energy recovery of waste. It contributes to optimization models developed in the author's workplace in the long term, which serve to simulate material flows in waste management and to search for an optimal waste management strategy. The main objective is to assess the potential for the use of heat produced in waste-to-energy plants as a key factor for the economy of these facilities. The thesis therefore represents an activity on the border of the fields of waste management and heating. Partial mathematical models were developed within the scope, for which it was necessary to collect input data, especially in relation with district heating networks. These models were then used in a comprehensive optimization model describing the integration of waste-to-energy plants with other heat sources. This main model was extended to include the environmental aspect.

Optimalizační algoritmus pro příhradové ocelové konstrukce / Optimization Algorithm for the Truss Steel StructuresZeizinger, Lukáš January 2021 (has links)
The work deals with the optimization of trusses construction building and transport machinery. The goal was to create an algorithm that can design an optimized design. The simulation took place on two experiments involving 52 sets of different entries, which are processed in detail into graphs. One-dimensional target mass or price function is used as part of optimization, but there is also an incorporated multidimensional purpose function. The finite element variation method for the beam system is used for the strength calculation of the truss structure and the genetic algorithm is used for optimization. At the end of the work, specific steps are formulated that lead to the most appropriate algorithm settings.
