Abstract
A new global minimization method that consists of a combination of conventional molecular dynamics and a local minimization scheme is presented. The new method was evaluated by comparison with another recent method which is based on simulated annealing. The test case consisted of a two-dimensional system of 32 particles interacting through a siliconlike potential. The new method was successful in determining the global minimum and the other method was not, even with considerable computational effort. These results and the relative simplicity of the new method suggest that it is preferable over the previous technique for global minimization problems.
