Genetic Algorithm Optimization of a Ship’s Bulbous Bow
, 2011 A genetic algorithm technique coupled with a potential flow solver has been applied to deal with the hydrodynamic optimization of a bulbous ship hull form. A non interactive procedure has been developed to minimize the objective function, related to the flow past a ship moving with steady forward speed in calm water.
