Approximate Subgraph Matching Algorithm for Dependency Graphs
The subgraph matching problem (subgraph isomorphism) is NP-complete. Previously, we designed
an exact subgraph matching (ESM) algorithm for dependency graphs using a backtracking approach
(http://esmalgorithm.sourceforge.net). We further designed an approximate subgraph matching (ASM)
algorithm that is capable of detecting approximate subgraph matching based on a subgraph
distance. Assume that the graph G and the subgraph Gs have m and n vertices, and km and kn edges
respectively, the total worst-case algorithm complexity is O(m^n * n(n-1)/2 * km * log m).
