Ring system perception

The ring system identification currently implemented in AUTONOM is a two-step process initiated by the ring system perception. The reliability of the ring perception routine is the crux of the naming algorithm. 

The rotation of phenol CLV led Dvornik and Edwards to first suggest that if the structure of atisine is based on an unrearranged diterpenoid skeleton, its A/B ring system bears a mirror image relation to that of the common diterpenes 17). Furthermore, the rotational arguments based on ajaconine chemistry reinforced this perceptive suggestion 17). 

It is assumed that ring information is available to the SDG program its perception is not discussed here. Three nonexclusive methods have been used to assign coordinates to ring systems (RSs) ... 

The aim of this paper is to change your perception of rings As basic justification for such an attempt I commend to you Mike Lynch s keynote address to the last conference in which he looked forward to the further development of graph theory to enable a sufficiently abstract way [to talk] about characteristics of ring systems , and drew attention to Lavoisier s observation that to change a science, one needs to change the language of the science . 

The preliminary ring perception phase, discussed earlier, delivers a complete list of all localized ring systems, including ring assemblies. Using only this information all the rings are... 

Ring perception is important for the analysis and description of chemical structure ring systems. There are a wide variety of rings sets and perception methods to choose from, many of which are specifically aimed at particular applications. Certain generalizations can be made, however, to give an indication of the best general purpose sets and methods.
