For the design of GTL's API the API of LEDA has served as a basis. GTL contains the classes needed to work with graphs, nodes and edges and some basic algorithms as building blocks for more complex graph algorithms.
Further algorithms are under work.
Designed to be extended to fit your own needs. Please refer to our homepage for details. Linux with egcs-1.0.3 or later. The latest version is GTL-0.2.4. It is currently maintained by Marcus Raitner.
