DESCRIPTION:Environmental and economic industry relies on high-performance
  materials such as lightweight alloys\, recyclable motor vehicle and build
 ing components\, and high efficiency lighting. Material properties as expr
 essed through crystal structure is crucial to this understanding. Based on
  first-principles calculations\, it is still impossible in most materials 
 to infer ground-state properties purely from a knowledge of their atomic c
 omponents. Many methods attempt to predict crystal structures and compound
  stability\, we explore models which infer the existence of structures on 
 the basis of combinatorics and geometric simplicity. Computational models 
 based on these first physics principles are called VASP codes. We illustra
 te the use of a statistical surrogate model to produce predictions of VASP
  codes as a function of a moderate number of VASP inputs. \n
