Available in PDF, EPUB and Kindle. Book excerpt: Abstract: "Experimental comparison of the running time of approximate string matching algorithms for the k differences problem is presented. Given a pattern string, a text string and an integer k, the task is to find all approximate occurrences of the pattern in the text with at most k differences (insertions, deletions, changes). Besides a new algorithm based on suffix automata, we consider six other algorithms based on different approaches including dynamic programming, Boyer-Moore string matching and the distribution of characters. It turns out that none of the algorithms is the best for all values of the problem parameters, and the speed differences between the methods can be large."
Download or read book String Searching Algorithms written by Graham A Stephen and published by World Scientific. This book was released on 1994-10-17 with total page 257 pages. Available in PDF, EPUB and Kindle. Book excerpt: String searching is a subject of both theoretical and practical interest in computer science. This book presents a bibliographic overview of the field and an anthology of detailed descriptions of the principal algorithms available. The aim is twofold: on the one hand, to provide an easy-to-read comparison of the available techniques in each area, and on the other, to furnish the reader with a reference to in-depth descriptions of the major algorithms. Topics covered include methods for finding exact and approximate string matches, calculating ‘edit’ distances between strings, finding common sequences and finding the longest repetitions within strings. For clarity, all the algorithms are presented in a uniform format and notation.

Download or read book Pattern Matching Algorithms written by Alberto Apostolico and published by Oxford University Press. This book was released on 1997-05-29 with total page 394 pages. Available in PDF, EPUB and Kindle. Book excerpt: Issues of matching and searching on elementary discrete structures arise pervasively in computer science and many of its applications, and their relevance is expected to grow as information is amassed and shared at an accelerating pace. Several algorithms were discovered as a result of these needs, which in turn created the subfield of Pattern Matching. This book provides an overview of the current state of Pattern Matching as seen by specialists who have devoted years of study to the field. It covers most of the basic principles and presents material advanced enough to faithfully portray the current frontier of research. Because of these recent advances, this is the right time for a book that brings together information relevant to both graduate students and specialists in need of an in-depth reference.

Download or read book Algorithms and Applications written by Tapio Elomaa and published by Springer. This book was released on 2010-04-08 with total page 268 pages. Available in PDF, EPUB and Kindle. Book excerpt: For many years Esko Ukkonen has played a major role in the advancement of computer science in Finland. He was the key person in the development of the school of algorithmic research and has contributed considerably to post-graduate education in his country. Esko Ukkonen has over the years worked within many areas of computer science, including numerical methods, complexity theory, theoretical aspects of compiler construction, and logic programming. However, the main focus of his research has been on algorithms and their applications. This Festschrift volume, published to honor Esko Ukkonen on his 60th birthday, includes 18 refereed contributions by his former PhD students and colleagues, with whom he has cooperated closely during the course of his career. The Festschrift was presented to Esko during a festive symposium organized at the University of Helsinki to celebrate his birthday. The essays primarily present research on computational pattern matching and string algorithms, two areas that have benefited significantly from the work of Esko Ukonen.

This book was released on 1997-10-15 with total page 206 pages. Available in PDF, EPUB and Kindle. Book excerpt: We use string processing to denote any use of computers to process and manage strings or sequences of symbols. This includes text retrieval, compression, computational biology, natural language processing, word theory, etc. Strings can also be extended to other dimensions, including images and complex objects, such as trees or graphs. These areas are important for many applications, including text, image or genetic databases. Nowadays, the most important motivation for research is searching and managing the World Wide Web. The Web contains terabytes of data and searching for information is becoming as difficult as finding a needle in a haystack. Future versions of this work-shop will focus on generic information retrieval, query languages, user interfaces and visualization tools.

Download or read book Jewels Of Stringology Text Algorithms written by Maxime Crochemore and published by World Scientific. This book was released on 2002-09-16 with total page 322 pages. Available in PDF, EPUB and Kindle. Book excerpt: The term “stringology” is a popular nickname for text algorithms, or algorithms on strings. This book deals with the most basic algorithms in the area. Most of them can be viewed as “algorithmic jewels” and deserve reader-friendly presentation. One of the main aims of the book is to present several of the most celebrated algorithms in a simple way by omitting obscuring details and separating algorithmic structure from combinatorial theoretical background. The book reflects the relationships between applications of text-algorithmic techniques and the classification of algorithms according to the measures of complexity considered. The text can be viewed as a parade of algorithms in which the main purpose is to discuss the foundations of the algorithms and their interconnections. One can partition the algorithmic problems discussed into practical and theoretical problems. Certainly, string matching and data compression are in the former class, while most problems related to symmetries and repetitions in texts are in the latter. However, all the problems are interesting from an algorithmic point of view and enable the reader to appreciate the importance of combinatorics on words as a tool in the design of efficient text algorithms.In most textbooks on algorithms and data structures, the presentation of efficient algorithms on words is quite short as compared to issues in graph theory, sorting, searching, and some other areas. At the same time, there are many presentations of interesting algorithms on words accessible only in journals and in a form directed mainly at specialists. This book fills the gap in the book literature on algorithms on words, and brings together the many results presently dispersed in the masses of journal articles. The presentation is reader-friendly; many examples and about two hundred figures illustrate nicely the behaviour of otherwise very complex algorithms.
Download or read book Handbook of Exact String Matching Algorithms written by Christian Charras and published by College PressPub Company. This book was released on 2004 with total page 238 pages. Available in PDF, EPUB and Kindle. Book excerpt: String matching is a very important subject in the wider domain of text processing. It consists of finding one, or more generally, all the occurrences of a string (more generally called a pattern) in a text. The Handbook of Exact String Matching Algorithms presents 38 methods for solving this problem. For each, it gives the main features, a description, its C code, an example and references.
