A method for the machine detection of near equivalence of major substructures in a molecule

J Comput Chem. 1986 Apr;7(2):129-139. doi: 10.1002/jcc.540070205.

Abstract

The use of the concept of near equivalence of substructures in a computer program concerned with organic synthesis requires a concrete definition of «nearness» and an efficient method for implementing the concept. Such a method has been devised and its use is described and examples are given.
