# OEDetermineRingComplexity¶

float OEDetermineRingComplexity(const OEChem::OEMolBase &mol)


Note

The molecule argument is const, so this function requires that the OEFindRingAtomsAndBonds perception activity has been performed prior to calling this function.

This is a non-SSSR adaptation of the ring complexity algorithm of [Gasteiger-1979]. The values of this complexity are generally somewhat lower, but are well-correlated and follow the spirit of the SSSR method.
