(1) Let is a given gene sequence, and are the beginning and end of the |

sequence respectively, is throdthod of spectral values; |

(2) Using _Curve mapping converted gene sequence to the corresponding numeric sequence; |

(3) Using fast Fourier transform to get spectral values and according to the formula (8); |

(4) Calculating gene sequence order parameter: |

, ; |

(5) Setting network parameter and ; |

(6) Order parameter evolution according to formula (14); |

(7) If > and >, then is recorded as a possible interal, and is divided |

equally into interals , …, , Repeat step 1 to step 7; |

(8) End. |
