Figure 1From: Parallelization of enumerating tree-like chemical compounds by breadth-first search orderExample of a family tree by BfsSimEnum and BfsMulEnum for C 2 O 2 H 2 and its separation by BfsEnumP1-3 with division depth 2. Molecular trees in gray color are regarded as invalid by the algorithms. It should be noted that hydrogen atoms are added as leaves at last.Back to article page
