Tight Lower Bounds on Graph Embedding Problems
Marek Cygan, Fedor V. Fomin, Alexander Golovnev +4
We prove that unless the Exponential Time Hypothesis (ETH) fails, deciding if there is a homomorphism from graph to graph cannot be done in time . We al…

Tight Bounds for Subgraph Isomorphism and Graph Homomorphism
Fedor V. Fomin, Alexander Golovnev, Alexander S. Kulikov +1
We prove that unless Exponential Time Hypothesis (ETH) fails, deciding if there is a homomorphism from graph to graph cannot be done in time . Combined…

Lower Bounds for the Graph Homomorphism Problem
Fedor V. Fomin, Alexander Golovnev, Alexander S. Kulikov +1
The graph homomorphism problem (HOM) asks whether the vertices of a given -vertex graph can be mapped to the vertices of a given -vertex graph such that each edge of…
