On graphtransverse matching problemsChurchley, Ross William 20 August 2012 (has links)
Given graphs G,H, is it possible to find a matching which, when deleted from G, destroys all copies of H? The answer is obvious for some inputs—notably, when G is a large complete graph the answer is “no”—but in general this can be a very difficult question. In this thesis, we study this decision problem when H is a fixed tree or cycle; our aim is to identify those H for which it can be solved efficiently.
The Htransverse matching problem, TM(H) for short, asks whether an input graph admits a matching M such that no subgraph of G − M is isomorphic to H. The main goal of this thesis is the following dichotomy. When H is a triangle or one of a few smalldiameter trees, there is a polynomialtime algorithm to find an Htransverse matching if one exists. However, TM(H) is NPcomplete when H is any longer cycle or a tree of diameter ≥ 4. In addition, we study the restriction of these problems to structured graph classes. / Graduate

Matching Concept Descriptions with Existential RestrictionsBaader, Franz, Küsters, Ralf 20 May 2022 (has links)
Matching of concepts with variables (concept patterns) is a relatively new operation that has been introduced in the context of description logics, originally to help filter out unimportant aspects of large concepts appearing in industrialstrength knowledge bases. Previous work has concentrated on (sub)languages of CLASSIC, which in particular do not allow for existential restrictions. In this work, we present sound and complete decision algorithms for the solvability of matching problems and for computing sets of matchers for matching problems in description logics with existential restrictions.

男女配對的模型及應用 / Men and women matching models and its applications詹博翔, Chan, Po Hsiang Unknown Date (has links)
近年來，越來越多單身男女希望能夠透過網路交友平台找到自己的另一半。本論文考慮一個網路交友平台的經營，期望能夠讓每位參與者都找到適合彼此的另一半。我們使用工作指派問題的數學模型整合配對問題及穩定室友問題的概念建構男女配對問題的數學模型。並且考慮多位交友對象、拒絕對象與分級制度等問題，分別提出不同的數學模型。最後，我們使用隨機產生的資料模擬參與者的雙向配度，以GAMS軟體求解，分析不同的配對結果，亦探討不同模型的難易度及求解所需之運算時間。 / In recent years, more and more single women and men hope that they can find their Mr. or Mrs. Right through the internet dating platform. This paper considers the operation of an internet dating platform which expects each participant to find the other half of each other. We propose mathematical models of the women and men matching problem by using the mathematical model of the assignment problem and integrating the idea of matching problem as well as the stable roommate problem. We also consider the problems of multiple dating objects, matching with rejection, and classification member. Finally, a simulate study will be performed by using the randomly generating data to simulate the twoway matching degree of each pair of participants. We analyze the different matching results obtained by the different models. We also present the difficulty of different models and the solution times.

Matching Concept Descriptions with Existential Restrictions RevisitedBaader, Franz, Küsters, Ralf 20 May 2022 (has links)
Matching of concepts against patterns is a new inference task in Description Logics, which was originally motivated by applications of the CLASSIC system. Consequently, the work on this problem was until now mostly concerned with sublanguages of the Classic language, which does not allow for existential restrictions. Motivated by an application in chemical process engineering, which requires a description language with existential restrictions, this paper investigates the matching problem in Description Logics with existential restrictions. It turns out that existential restrictions make matching more complex in two respects. First, whereas matching in sublanguages of CLASSIC is polynomial, deciding the existence of matchers is an NPcomplete problem in the presence of existential restrictions. Second, whereas in sublanguages of Classic solvable matching problems have a unique least matcher, this is not the case for languages with existential restrictions. Thus, it is not a priori clear which of the (possibly infinitely many) matchers should be returned by a matching algorithm. After determining the complexity of the decision problem, the present paper first investigates the question of what are 'interesting' sets of matchers, and then describes algorithms for computing these sets for the languages EL (which allows for conjunction and existential restrictions) and ALE (which additionally allows for value restrictions, primitive negation, and the bottom concept). / An abridged version of this technical report has been submitted to KR 2000.

Previous issue date: 20110218 / Coordenação de Aperfeiçoamento de Pessoal de Nível Superior  CAPES / This work considers three relevant NPhard problems. The firstone is the onedimensional
cutting stock problem in which the nonused material in the cutting patterns may be used
in the future. For this problem we analyze the existing mathematical models, propose new
models, design a heuristic and two metaheuristic approaches, being their performances
improved by using parallel programming, and solve instances, practical and randomly
generated, from the literature. The computational experiments were quite good for all
tested instances. The second problem we consider is the stable roommates problem (a
variant of the stable matching problem). For this we give two mathematical programming
models, sequential and parallel implementations of a Tabu Search, and a BranchandBound. Also, we report computational experiments to instances of the problem. The
last problem we consider is the compartmentalized knapsack problem (a generalization
of the knapsack problem) for which we analyze a quadratic integer model and give a
linear integer model. We design a greedy heuristic and a GRASP algorithm, that uses
pathrelinking, and solve randomly generated instances. All parallel implementations use
Graphics Processing Units (GPUs). / Este trabalho considera três problemas, NPdifíceis, relevantes de estudo em otimização

problema analisamos os modelos matemáticos existentes, propomos novos modelos,
projetamos uma heurística construtiva e duas metaheurísticas, sendo seus desempenhos
melhorados com programação paralela, e resolvemos instâncias, práticas e aleatórias,
encontradas na literatura; sendo os experimentos computacionais muito bons para todas as

implementação sequencial e uma paralela de uma Tabu Search, e um BranchandBound. Também reportamos experimentos computacionais para instâncias do problema.
O último problema considerado é o da mochila compartimentada (uma generalização do
problema clássico da mochila), para o qual analisamos uma modelagem quadrática inteira
e propomos um modelo linear inteiro; também projetamos uma heurística gulosa, um
algoritmo GRASP, que usa pathrelinking, e resolvemos intâncias geradas aleatóriamente.
Todas as implementações em paralelo usam unidades de processamento gráfico (Graphics
Processing Units, GPUs).
