5 Preface This Festschrift is dedicated to Esko Ukkonen on the occasion of his 60th birthday on January 26, It contains contributions by his former PhD students and colleagues with whom he cooperated closely within his career. The Festschrift was presented to Esko during a festive symposium organized at the University of Helsinki to celebrate his birthday. Esko Ukkonen has worked on many areas of computer science, including numerical methods, complexity theory, theoretical aspects of compiler construction, and logic programming. However, his main research interest over the years has been algorithms, with applications. Esko s style of work has been to collaborate closely with scientists from other areas and to study their computational needs. From an understanding of available data the work progresses to the formulation of computational concepts, i.e., finding out what should be computed. The properties of the concepts are then analyzed, algorithms are designed, their behavior is analyzed, the methods are implemented and taken to real applications. This style of work has been very successful throughout his career: Esko has formulated and analyzed many central concepts in computational data analysis. Combining applications and algorithms is also the central theme in the Center of Excellence, Algodan, directed by Esko. Perhaps the most important scientific areas of Esko Ukkonen are computational pattern matching and string algorithms. He has contributed significantly to the development of these overlapping fields and has helped them to find their own identity. Most of the contributions in this volume concern computational pattern matching or string algorithms. Esko Ukkonen has had a major role in the development of Finnish computer science. He was the key person in the development of the school of algorithmic research in Finland, and he has had a major role in PhD education. The editors of this volume are grateful to Esko for the insightful guidance that they received from him when they were his PhD students. January 2010 Tapio Elomaa Heikki Mannila Pekka Orponen Acknowledgements We would like to thank everybody who contributed to this Festschrift: the authors for their interesting articles, the colleagues and PhD students who helped proofread the contributions, Greger Lindén for technical assisstance, and Veli Mäkinen for organizing the seminar to honor Esko s birthday.
