Our research centers on the dynamics and structure of atomic and molecular clusters. We are particularly interested in the motion induced in the "solvent" cluster when a solute chromophore is electronically excited or emits. In addition, we are studying several approaches to locating the most stable geometry of clusters. This requires many-dimensional nonlinear optimitation techniques. We have used several variants of the genetic algorithm and basin-hopping methods, as well as more traditional simulated annealing approaches. The diagram shows the "evolution" of a Si7 cluster using a genetic algorithm. Shown is the best (most stable) individual in a population of candidate individuals at each generation. New individuals ("offspring") are created in the next generation by the exchange of genetic information between individuals in the gene pool. By the twelfth generation, the best possible individual (the global minimum) has been created.
