V401 Find Compatible Node-Nets in an Incompatibility Graph

Routine ID: V401
Author(s): A. ReglLibrary: MATHLIB
Submitter: H. GroteSubmitted: 01.02.1974
Language: FortranRevised: 15.09.1978

GRAPH finds all compatible sets of events (nodes) in an incompatibility graph (in which incompatible events or nodes are connected). It is useful, for example, in track-matching programs for eliminating spurious tracks.

On each call, one compatible node-set is returned. The user may decide in the first call whether the solutions should be evaluated over the whole graph or subgraph by subgraph. Indications on "end-of-graph" and, if applicable, "end-of-subgraph" are given.
