Abstract:
1. A computer based method for optimizing a design of a hydrodynamic or aerodynamic structure, the method comprising the steps of: (a) creating an initial population of a plurality of individual parameter sets the parameter sets comprising object parameters describing the design to be optimized and setting the initial population as a current parent population; (b) for each individual parameter set in a parent population mutating, by the computer, the parameters and optionally recombining the parameters to create an offspring population of individual parameter sets, wherein a strength of an individual object parameter mutation is enlarged by a noise contribution, wherein the noise contribution is added to said individual object parameter value whereby the noise contribution is a mutation term, to enhance the robustness of the optimization; (c) evaluating, by the computer, a quality of each individual in the offspring population; (d) selecting individuals of the offspring population to be the next parent generation based upon said quality; and (e) repeating steps (b) through (d) until a termination criterion is reached to optimize the design.
