Direct search for optimal parameters within simulation models

The tool of systems simulation can be improved by superposing optimization techniques onto the computer model of the object or system investigated. Direct search methods for parameter optimization are applicable in a much wider field than any other technique. Outstanding among such partly heuristic methods is one that is based on principles of organic evolution. The results of a comprehensive test program in which all important algorithms have been compared reveal the superiority of this evolution strategy. Reference is made to examples of actual application.
