Classes of Methods
Historically the first global optimization method used is probably multistart, i.e., local minimization is started from several points and the best local minimum found is taken as an estimate of the global minimum.
A lot of global optimization methods have been suggested. The ideas behind these algorithms are fewer than the methods so we may describe a number of classes covering most of the methods. Such a classification is of course not unique, several classification schemes could be used depending on which features that are used in the classification. For the largest class "Search Methods" we base our classification on the strategies local-global-adaptive in choosing points. The classes in bold are examples only.
A crude classification is
