Abstract

Abstract

The validity of the genetic algorithm in estimating the directional spreading,reflection coefficient and reflective line distance is studied by numerical simulation.The genetic algorithm is verified by the numerical simulation of wave cross-spectrum and surface elevations.The directional spreading of the incident wave,reflection coefficient and reflection line distance are obtained by optimizing a fitness parameter which is a function of the difference between the simulated and theoretical cross-spectra.The numerical simulation results show that the genetic algorithm can accurately separate the incident and reflected wave in multi-directional reflective wave fields without a prior knowledge of the reflection line position.The analytic and model test results indicate that the genetic algorithm can be applied to analyzing the multi-directional random wave reflection.
