| Abstract: | A real-code hybrid genetic algorithm for nano-particle sizing with photon correlation spectroscopy is presented.With ergodic properties of chaos and simulated annealing algorithm,our algorithm shortens inversion range automatically.It has a relatively strong local searching ability.Numerical simulations are performed for mono-disperse particle system under noise-free condition and noise with various noise levels.Inversion of experimental results of 90nm standard samples of polystyrene particles is made.It s... |
