Structure Search in the Framework of Genetic Algorithm
In the world of creation, natural materials may be found in various phases with distinct properties. As a traditional example, carbon is found in two natural phases, the first one is diamond which is a very hard and transparent material, while the second phase is graphite which is a layered dark material. The large abundance of graphite (coal) in nature shows the more thermodynamic stability of this phase of carbon, and therefore diamond is recognized as a metastable phase of carbon that can form under certain conditions (deep in the earth: high pressures).
