LEDA Library of Efficient Data Types and Algorithms

LEDA is AlgoSol’s C++ class library for efficient data types and algorithms. LEDA provides algorithmic in-depth knowledge in the field of graph- and network problems, geometric computations, combinatorial optimization and other. It offers a huge number of relevant algorithms in an easy-to-use and efficient form.

You don't have to re-invent the wheel: Save time and space with LEDA's building blocks! LEDA offers all of the relevant algorithm building blocks in an easy-to-use and efficient form dealing with objects such as graphs, sequences, dictionaries, trees, points, flows, matchings, segments, shortest paths, and many more. LEDA’s roots go back to the 90's, and LEDA is one of the most popular software libraries currently available as evidenced by a community of talented developers from 55 countries.
