Flexible Pattern Matching in Strings: Practical On-line Search Algorithms for Texts and Biological Sequences

Introduction to "Flexible Pattern Matching in Strings"

Welcome to "Flexible Pattern Matching in Strings: Practical On-line Search Algorithms for Texts and Biological Sequences." This book is a comprehensive exploration into the fascinating and highly practical realm of string processing and pattern matching, a cornerstone of modern computational science. Authored by Gonzalo Navarro and Mathieu Raffinot, this guide seeks to bridge the gap between theoretical computer science and real-world applications, particularly in fields as diverse as text processing and bioinformatics.

The art and science of searching for meaningful patterns in sequences, whether natural language or biological data, has evolved significantly over the years. Our book not only delves deep into online search algorithms but also equips readers with powerful, flexible tools to handle complex structures and irregularities in data. By coupling theoretical rigor with practical insights, we provide a roadmap to mastering this essential skill set.

Detailed Summary of the Book

In this book, we explore the rich landscape of flexible pattern matching, an advanced topic in string algorithms with applications spanning numerous domains. Unlike traditional exact pattern matching, where a query string must exactly match a substring, flexible pattern matching introduces tolerances or rules for "approximate" matches—making it highly relevant in real-world scenarios.

We begin by building foundational knowledge, introducing core concepts of string manipulation, coding schemes, and data structures like suffix trees, suffix arrays, and automata. The subsequent chapters dive into the heart of flexible pattern matching, explaining algorithms for approximate matching, regular expressions, and matching with "don't care" symbols.

You will also find detailed discussions on online versus offline pattern matching strategies, highlighting their strengths and trade-offs. Special emphasis is given to string matching in biological sequences, where approximate matching is particularly useful due to the inherent variability in DNA, RNA, and protein sequences.

This book balances theoretical depth with practical implementation advice. Numerous algorithms are described both conceptually and with pseudocode, enabling readers to translate them into working software. We also include performance analyses, comparisons, and use cases to help readers select the most suitable approach for their specific problems.
