Alexander Vasilyev: Approach of lazy calculations in application to topological graph indices in Sage. Introduction to a new molecular class.

Abstract: Previously we introduced a molecular graph class based on standard Sage graph class. The classical approach of object-oriented model proved to be not at its best on a huge amount of data. The conception of lazy calculations and some optimizations allowed us to dramatically increase the performance. We will talk about the nature of such problems in calculations and some solutions to avoid them.
