Professor Sartaj Kumar Sahni (born July 22, 1949, in Pune, India) is a computer scientist based in the United States, and is one of the pioneers[citation needed] in the field of data structures. He is a distinguished professor in the Department of Computer and Information Science and Engineering at the University of Florida.[1]
Sahni received his BTech degree in electrical engineering from the Indian Institute of Technology Kanpur.[2] Following this, he undertook his graduate studies at Cornell University in the USA, earning a PhD degree in 1973, under the supervision of Ellis Horowitz.[3]
Sahni has published over 280 research papers and written 15 textbooks.[4] His research publications are on the design and analysis of efficient algorithms, data structures, parallel computing, interconnection networks, design automation, and medical algorithms.
With his advisor Ellis Horowitz, Sahni wrote two widely used textbooks, Fundamentals of Computer Algorithms and Fundamentals of Data Structures. He has also written highly cited research papers on the NP-completeness of approximately solving certain optimization problems,[5] on open shop scheduling,[6] on parallel algorithms for matrix multiplication and their application in graph theory,[7] and on improved exponential time exact algorithms for the subset sum problem,[8] among his many other research results.
In 1997, Sahni was awarded the IEEE Computer Society's Taylor L. Booth Education Award[9] and in 2003 he was awarded the IEEE Computer Society McDowell Award.[10] Sahni was also awarded the 2003 Karl V. Karlstrom Outstanding Educator Award of the Association for Computing Machinery.[11]
Professor Sahni is a member of the European Academy of Sciences.[12] He was elected as a Fellow of the Institute of Electrical and Electronics Engineers in 1988,[13] and of the Association for Computing Machinery in 1996;[14] he is also a fellow of the American Association for the Advancement of Science, elected in 1995.[15] He is a Distinguished Alumnus of the Indian Institute of Technology, Kanpur.[2]
The Handbook of Data Structures and Applications was first published over a decade ago. This second edition aims to update the first by focusing on areas of research in data structures that have seen significant progress. While the discipline of data structures has not matured as rapidly as other areas of computer science, the book aims to update those areas that have seen advances.
Retaining the seven-part structure of the first edition, the handbook begins with a review of introductory material, followed by a discussion of well-known classes of data structures, Priority Queues, Dictionary Structures, and Multidimensional structures. The editors next analyze miscellaneous data structures, which are well-known structures that elude easy classification. The book then addresses mechanisms and tools that were developed to facilitate the use of data structures in real programs. It concludes with an examination of the applications of data structures.
Four new chapters have been added on Bloom Filters, Binary Decision Diagrams, Data Structures for Cheminformatics, and Data Structures for Big Data Stores, and updates have been made to other chapters that appeared in the first edition.
The Handbook is invaluable for suggesting new ideas for research in data structures, and for revealing application contexts in which they can be deployed. Practitioners devising algorithms will gain insight into organizing data, allowing them to solve algorithmic problems more efficiently.

This handbook is a voluminous collection of 67 articles on a variety of data structures and their applications. Many articles are written by well-known experts with a focus on explaining basic ideas and surveying results. Overall, one gets an interesting overview of this central area of computer science.
Although there are many advanced and specialized texts and handbooks on algorithms, until now there was no book that focused exclusively on the wide variety of data structures that have been reported in the literature. The Handbook of Data Structures and Applications responds to the needs of students, professionals, and researchers who need a mains
