Hierarchical Crossover in Genetic Algorithms [PDF]
, 1996 This paper identifies the limitations of conventional crossover in genetic algorithms when operating on two chromosomes of differing lengths. To address these problems, the concept of a Semantic Hierarchy (i.e.

Soft-SAFT modeling of vapour liquid equilibria of nitriles and their mixtures [PDF]
, 2010 Nitriles are strong polar compounds showing a highly non-ideal behavior, which makes them challenging systems from a modeling point of view; in spite of this, accurate predictions for the vapor-liquid equilibria of these systems are needed, as some of ...
