Basin-hopping

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 Jonathan Doye.

[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.
