We have compared the recently introduced generalized simulated annealing ~GSA! with conventional simulated annealing ~CSA!. GSA was tested as a tool to obtain the ground-state geometry of molecules. We have used selected silicon clusters (Sin , n54 – 7,10) as test cases. Total energies were calculated through tightbinding molecular dynamics. We have found(More)
This article introduces an efficient method to generate structural models for medium-sized silicon clusters. Geometrical information obtained from previous investigations of small clusters is initially sorted and then introduced into our predictor algorithm in order to generate structural models for large clusters. The method predicts geometries whose(More)
