Basin-hopping

An animation of the basin-hopping algorithm finding the icosahedral global minimum for a 13 atom Lennard-Jones cluster.

In applied mathematics, Basin-hopping is a global optimization technique that iterates by performing random perturbation of coordinates, performing local optimization, and accepting or rejecting new coordinates based on a minimized function value.[1] The algorithm was described in 1997 by David J. Wales and .[2] It is a particularly useful algorithm for global optimization in very high-dimensional landscapes, such as finding the minimum energy structure for molecules. The method is inspired from Monte-Carlo Minimization first suggested by Li and Scheraga.[3]
