Web1 mei 2001 · Subgraph isomorphism Maximum common subgraph Minimum common supergraph 1. Introduction Graphs are one of the most abstract and hence powerful structures for modeling problems and describing structured objects or concepts. WebRather than incrementally constructing candidate graphs, the algorithm takes the opposite route. The set of all graphs are considered to be isomorphic to one another to begin with. Then edges that contradict such an assertion are filtered out in one or more iterations until the algorithm converges to the maximal common subgraph(s).
