Multiobjective Optimal Algorithm for Automatic Calibration of Daily Streamflow Forecasting Model

Algorithm 1

For each non-dominated individual in population

Begin

  If1 is none, then add into directly;

  Else1

  Begin

    If2 is dominated by one member in , then continue;

    Else2

    Begin

      add into and delete the members in dominated by ;

      If3 the length of is larger than the preset size of then

      Begin

        Calculate the crowd distance of individuals in ;

        Delete the individuals with the minimum crowd distance;

      End if3

    End else2

  End else1

End for
