Application of the diffusion equation method of global optimization to water clusters

In this paper, we investigate the behavior of the recently developed diffusion equation method (DEM) for water cluster The DEM is a global optimization method that involves the deformation of the potential energy surface to remove local minima of high energy. The deformed potential energy surface corresponds to the solution F(x,t) of the diffusion original energy function f(x) as the initial condition, i.e., F(x,0)=f(x)
