The fruit fly optimization algorithm is applied to identify the structural parameters in the ship manoeuvring response models.The deformed zig-zag tests are predicted by using the identified models.The validity of the proposed method is verified by comparing the predicted results with the zig-zag test data.Results show that the proposed method has the advantages of simple algorithm to construct,less parameters to adjust and local minima more avoidable.
