(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.
