Maximum common subgraph isomorphism

WebFor these parts, we calculate the maximum common subgraph (MCS) between G and s d to find a subgraph of s d which is subgraph-isomorphic to G with maximum nodes. The substructures which do not appear in the m c s are removed (Lines 9–11). Web3 apr. 2024 · The performance of a branch-and-bound (BnB) algorithm for maximum common subgraph (MCS) problem and its related problems, like maximum common connected subgraph (MCCS) and induced Subgraph Isomorphism (SI), crucially depends on the branching heuristic. We propose a branching heuristic inspired from reinforcement …

WebAbstract We consider the maximum common connected edge subgraph problem and the maximum common connected induced subgraph problem for simple graphs with labeled vertices (or labeled edges). The former is to find a connected graph with the maximum number of edges that is isomorphic to a subgraph of each of the two input graphs. In theoretical computer science, the subgraph isomorphism problem is a computational task in which two graphs G and H are given as input, and one must determine whether G contains a subgraph that is isomorphic to H. Subgraph isomorphism is a generalization of both the maximum … Meer weergeven To prove subgraph isomorphism is NP-complete, it must be formulated as a decision problem.
