WebSep 24, 2004 · For graph alignment, a polynomial-time algorithm probably does not exist. Already simpler graph matching problems such as the subgraph isomorphism problem (deciding whether a graph contains a given subgraph) (15, 16) or finding the largest common subgraph of two graphs are NP-complete and NP-hard, respectively. Thus, an … WebThe problem of graph alignment is to find corresponding nodes between a pair of graphs. Past work has treated the problem in a monolithic fashion, with the graph as input and the alignment as output, offering limited opportunities to adapt the algorithm to task requirements or input graph characteristics.
