GEGA

GEGA stands for the ("ab initio") Gradient Embedded Genetic Algorithm, a program for finding the global minima of clusters. The Author is [http://zarbi.chem.yale.edu/~anastassia/ Anastassia Alexandrova] (Utah State University, and later Yale University). GEGA employs geometry-cuts for the Genetic Algorithm procedure, "ab initio" level of computation for geometry optimization and vibrational frequency analysis (GEGA works with local minima only), and a specific mutational procedure based on the so called "kick technique".
