FLOYD is a MATLAB library which demonstrates Floyd's algorithm for finding the shortest distance between every pair of nodes in a directed graph.
FLOYD is available in a C version and a C++ version and a FORTRAN90 version and a FORTRAN77 version and a MATLAB version.
BELLMAN_FORD, a MATLAB library which implements the Bellman-Ford algorithm for finding the shortest distance from a given node to all other nodes in a directed graph whose edges have been assigned real-valued lengths.
CITIES, a MATLAB 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 MATLAB program which runs a simple example of Dijkstra's minimum distance algorithm for graphs.
GRAFPACK, a FORTRAN90 library which computes various quantities associated with mathematical graphs.
GRAPH_REPRESENTATION, a data directory of examples of ways of representing abstract mathematical graphs
GRF, a data directory which contains a description of the GRF format and some examples.
GRF_IO, a MATLAB library which reads and writes GRF files.
GRF_TO_EPS, a FORTRAN90 library which can make an encapsulated PostScript image of a GRF file.
SUBSET, a MATLAB library which generates, ranks and unranks various combinatorial objects.
TOMS097, a MATLAB library which computes the distance between all pairs of nodes in a directed graph with weighted edges, using Floyd's algorithm.
