AllDifferent-based filtering for subgraph isomorphism
The subgraph isomorphism problem involves deciding if there exists a copy of a pattern graph in a target graph. This problem may be solved by a complete tree search combined with filtering techniques that aim at pruning branches that do not contain solutions. We introduce a new filtering algorithm based on local all different constraints. We show that this filtering is stronger than other exist...
متن کاملFiltering for Subgraph Isomorphism
A subgraph isomorphism problem consists in deciding if there exists a copy of a pattern graph in a target graph. We introduce in this paper a filtering algorithm dedicated to this problem. The main idea is to label every node with respect to its relationships with other nodes of the graph, and to define a partial order on these labels in order to express compatibility of labels for subgraph iso...
متن کاملLower Bounds for Subgraph Isomorphism
We consider the computational complexity of determining whether an Erdős-Rényi random graph contains a subgraph isomorphic to a fixed pattern, such as a clique or cycle of constant size. We give an overview of unconditional lower bounds for this problem, focusing on circuits and formulas in the AC 0 and monotone settings. 1 Background and preliminaries The subgraph isomorphism problem is the co...
متن کاملBetween Subgraph Isomorphism and Maximum Common Subgraph
When a small pattern graph does not occur inside a larger target graph, we can ask how to find “as much of the pattern as possible” inside the target graph. In general, this is known as the maximum common subgraph problem, which is much more computationally challenging in practice than subgraph isomorphism. We introduce a restricted alternative, where we ask if all but k vertices from the patte...
