Figure 8From: Systematic benchmark of substructure search in molecular graphs - From Ullmann to VF2Explicit vs. Implicit hydrogens run time histogram. Histogram of VF2 (up) and Ullmann (down) matching times with (left) and without (right) explicit hydrogens on the Substructure Search Set. The algorithms search for all occurrences of the substructure. All plots are double logarithmic and times are given in milliseconds (ms).Back to article page
