In the core computer science areas--data structures, graph and network algorithms, and computational geometry--LEDA is the first library to cover all material found in the standard textbooks. Written in C++ and freely available worldwide on a variety of hardware, the software is installed at hundreds of sites. This book, written by the main authors of LEDA, is the definitive account of how the system operates and how it can be used. The authors supply plentiful examples from a range of areas to show practical uses of the library, making the book essential for all researchers in algorithms, data structures and computational geometry.
