I. INTRODUCTION
The structure of solid materials, the most stable (lowest energy or no energy) will contribute to understanding the relationship between atoms. This is extremely important in check during scientific procedures. For a group of atomic structure is larger and more difficult to make because of the complex structure of the energy calculation is based on the number of atoms. The education process may take more than one year in order to calculate the correct energy. Therefore, we find new ways to reduce the value of any such alternative to the above process is reduced. The structure prediction The process is calculated by the computer This process is very simple and the cost was more than an experiment in the laboratory is very significant. It can also be used to determine the materials that were not capable of such structures in their normal pressure inside large planets. Which perhaps have discovered new materials. Which can lead to the synthesis and applications to take advantage
of that, we do not know anything about the structure with low power consumption. Is there any reason why the structure is based on a random search or Ab initio random structure searching is done on the computation is based on the requirements and principles of science to apply. In our research, the development of a random search process easier. Effective and can be used in conjunction with the density functional theory DFT, or to obtain a stable structure. In this research, the Java application development process and structure for the program VASP 5.2 for calculating the DFT.
