TD-GEN: Graph Generation With Tree Decomposition

no code implementations20 Jun 2021 Hamed Shirzad, Hossein Hajimirsadeghi, Amir H. Abdi, Greg Mori

We propose TD-GEN, a graph generation framework based on tree decomposition, and introduce a reduced upper bound on the maximum number of decisions needed for graph generation.
