Abstract (sommario):
This thesis addresses the problem of backtracking strategies in test generation. First, a methodology which uses status of absolute dominators as a means for causing backtracking during the test generation process is presented. Then, different heuristics that force the test generation to execute the backtracking procedure are investigated. Experiments which generated test patterns for over 30,000 faults have been used to evaluate these heuristics. According to the experimental results, we recommend a new backtracking strategy that has the best performance among the six strategies explored in t

Abstract (sommario):
Although the parsing phase of the modern compiler has been automated in a machine independent fashion, the diversity of computer architectures inhibits automating the code generation phase. During code generation, some intermediate representation of a source program is transformed into actual machine instructions. The need for portable compilers has driven research towards the automatic generation of code generators.;This research investigates the use of a backtracking LR parser that treats code generation as a series of tree transformations.

Abstract (sommario):
Sudoku solvers are a widely researched topic among mathematicians and computer scientists. This report investigates the differences in execution time and time complexity between backtracking and human strategies for classes with 17-21 clues. Backtracking is compared to our implementation of human strategies with test data that contains 99 Sudoku puzzles for each class. The study shows that the execution time and time complexity is improved for human strategies compared to backtracking for each class. The conclusion shows that it is always favorable to implement the human strategies investigate

Abstract (sommario):
Regular expressions are ubiquitous in computer science. Originally defined by Kleene in 1956, they have become a staple of the computer science undergraduate curriculum. Practical applications of regular expressions are numerous, ranging from compiler construction through smart text editors to network intrusion detection systems. Despite having been vigorously studied and formalized in many ways, recent practical implementations of regular expressions have drawn criticism for their use of a non-standard backtracking algorithm. In this research, we investigate the reasons for this deviation and

Abstract (sommario):
Two implementations of the backtracking algorithm for solving Sudoku puzzles as well as their dependence on the representations of the problem have been studied in order to ascertain pros and cons of different approaches. For each backtracking step, empty cells could be assigned numbers sequentially or, by using a greedy heuristic, by the probability that guessed numbers were more likely to be correct. Representations of the Sudoku puzzles varied from a n2 matrix to a n3 matrix, as well as a combination of both. This study shows that (1) a sequential approach has better best case times but poor

Abstract (sommario):
A common concern for people using computer databases is becoming "lost" within the complex hierarchy of entries. Most direct manipulation interface design guidelines suggest designers should include a feature for “undoing” user inputs (Smith and Mosier, 1986). In the case of a database, undo translates to backtracking support. The first purpose of this research was to confirm that computer-supported backtracking tools reduce navigation time over manual backtracking. The second purpose was to compare navigation times among a subset of backtracking tools. The third purpose was to determine if us

Abstract (sommario):
The optimization of photovoltaic (PV) power generation system requires an accurate system performance model capable of validating the PV system optimization design. Currently, many commercial PV system modeling programs are available, but those programs are not able to model PV systems on a distorted ground level. Furthermore, they were not designed to optimize PV systems that are already installed. To solve these types of problems, this thesis proposes an optimization method using model simulations and a MATLAB-based PV system performance model. The optimization method is particularly designe

This thesis studies two problems centered around non-backtracking walks on graphs. First, we analyze the spectrum of the non-backtracking matrix of a graph. We show how to obtain the eigenvectors of the non-backtracking matrix using a smaller matrix and in doing so, create a block diagonal decomposition which more clearly expresses the non-backtracking matrix eigenvalues. Additionally, we develop upper and lower bounds on the matrix spectrum and use the spectrum to investigate properties of the graph.

Abstract (sommario):
Transcription elongation by RNA polymerase II (RNAPII) is a highly complex process in which RNAPII moves by Brownian motion. Therefore, transcript elongation is a surprisingly interrupted process, including frequent pausing, backtracking and arrest (collectively referred to as transcription stress). A backtracked RNAPII is specifically recognized by transcription factor TFIIS, which can stimulate the intrinsic RNA endonuclease activity of RNAPII to cleave the transcript so that the polymerase active site regains control of the RNA end.

Abstract (sommario):
Many utility-scale solar farms use horizontal single axis tracking to follow the sun throughout the day and produce more energy. Solar farms on skewed topography produce complex shading patterns that require precise modeling techniques to determine the energy output. To accomplish this, MATLAB was used in conjunction with NREL weather predictions to predict shading shapes and energy outputs. The MATLAB models effectively predicted the sun’s position in the sky, panel tilt angle throughout the day, irradiance, cell temperature, and shading size.

An interesting problem in proof theory is to find representations of proof that do not distinguish between proofs that are ‘morally’ the same. For many logics, the presentation of proofs in a traditional formalism, such as Gentzen’s sequent calculus, introduces artificial syntactic structure called ‘bureaucracy’; e.g., an arbitrary ordering of freely permutable inferences. A proof system that is free of bureaucracy is called canonical for a logic.

Many real life problems can be formulated as constraint satisfaction problems <i>(CSPs)</i>. Backtracking search algorithms are usually employed to solve <i>CSPs</i> and in backtracking search the choice of branching strategies can be critical since they specify how a search algorithm can instantiate a variable and how a problem can be reduced into subproblems; that is, they define a search tree.

Abstract (sommario):
Dans cette thèse, nous étudions deux problèmes d'apprentissage automatique : (I) la détection des communautés et (II) l'appariement adaptatif. I) Il est bien connu que beaucoup de réseaux ont une structure en communautés. La détection de ces communautés nous aide à comprendre et exploiter des réseaux de tout genre. Cette thèse considère principalement la détection des communautés par des méthodes spectrales utilisant des vecteurs propres associés à des matrices choisiesavec soin. Nous faisons une analyse de leur performance sur des graphes artificiels. Au lieu du modèle classique connu sous le

Abstract (sommario):
Face au déluge actuel de données principalement non structurées, les graphes ont démontré, dans une variété de domaines scientifiques, leur importance croissante comme language abstrait pour décrire des interactions complexes entre des objets complexes. L’un des principaux défis posés par l’étude de ces réseaux est l’inférence de propriétés macroscopiques à grande échelle, affectant un grand nombre d’objets ou d’agents, sur la seule base des interactions microscopiquesqu’entretiennent leurs constituants élémentaires. La physique statistique, créée précisément dans le but d’obtenir les lois mac

Abstract (sommario):
Methods for aproximate string matching of various sequences used in bioinformatics are crucial part of development in this branch. Tasks are of very large time complexity and therefore we want create a hardware platform for acceleration of these computations. Goal of this work is to design a generalized architecture based on FPGA technology, which can work with various types of sequences. Designed acceleration card will use especially dynamic algorithms like Needleman-Wunsch and Smith-Waterman.

Abstract (sommario):
碩士<br>國立中正大學<br>哲學研究所<br>101<br>Backtracking subjunctive conditionals are those of which subjunctive conditionals to be evaluated base on backtracking to preconditions of how things would be caused. David Lewis (1979) and Keith DeRose (2010) both think that backtracking has unwelcome consequence. David Lewis points out that backtracking is non-standard and unstable. Keith DeRose thinks that backtracking is unavailable for future directed subjunctive conditionals. In this thesis, the objective is to propose backtracking subjunctive conditionals for some applications especially in software engin
