CITIES, a FORTRAN90 library which handles various problems associated with a set of “cities” on a map.

CITIES, a dataset directory which contains a number of city distance datasets.

CODEPACK, a FORTRAN90 library which computes “codes” that can determine if two graphs are isomorphic.

DIJKSTRA, a C++ program which runs a simple example of Dijkstra’s minimum distance algorithm for graphs.
