In recent years there has been an unprecedented need for algorithms on strings. This is due to the increasing need for fast an innovative algorithms that can help researchers from other scientific aras conduct research more efficiently. Computational biology, computerized music analysis and web searching are some of the research areas that constantly provide new problem on strings or require more efficient algorithms for known problems. In addition, many theoretical problems from Computer Science are closely related to well-known problems on strings. This volume aims to provide some new methods and solutions for a subset of all these problems. The organization of the book allows the readerto either obtain a broad overview or detailed knowledge of some of the mian topics in string algorithmics. Each chapter of the book has been written by leading researchers in this field.
