An Algorithm for Finding the Smallest Set of Smallest Rings

WebbThe perception of a set of rings forms the basis for a number of chemoinformatics applications, e.g. the systematic naming of compounds, the calculation of molecular descriptors, the matching of SMARTS expressions, and the generation of atomic coordinates. We introduce the concept of unique ring families (URFs) as an extension of … WebbBecause a set of all possible rings in a graph {C} can be described by two PID matrices Pe and P¿, then the next step was to select SSSR members {CSSsr> within {C}. The XOR operation (20) was introduced to select the SSSR from {C}.
