Abstract:
A method for automatic, computer-based optimization of a technical systemsaid technical system being described by a state {right arrow over (x)} with state-variables x&ngr;, &ngr;=1, . . . , N, and said technical system rated in a state {right arrow over (x)} by a measure f({right arrow over (x)}), and said method determining an improved state {right arrow over (x)}opt with an improved measure f({right arrow over (x)}opt) and said improved state satisfying one or more additional constraints and said method comprising the following steps: an initialization-step as step 1, choosing a first state as current-state {right arrow over (y)} of said technical system said first state already satisfying said additional constraints, and a ruin-step as step 2, destroying said current-state by selecting a subset B of said current-state's state-variables y&ngr;&mgr;, &mgr;=1, . . . , M, and excluding them from the current-state building a reduced-state, and a recreation-step as step 3, determining a recreated-state {right arrow over (Z)}said recreated-state being determined by extending said reduced-state by substitute-state-variables Z&ngr;&mgr;, substituting said excluded-state-variables of said subset B, and said recreated-state satisfying said additional constraints, and determination of said substitute-state-variables is not guided by the values of said excluded-state-variables, and an acceptance-step as step 4, deciding if said recreated-state is to be accepted as a new current-state {right arrow over (y)}, and an iteration-step as step 5, deciding to iterate said method beginning with step 2.
