| The fitness of each particle is taken as the particle extremum pbest, and the individual extremum is selected as the population extremum gbest. |
| This table only gives the number of events for a length and an extremum. |
| Moreover, the probability at which in one year the extremum of temperature will not be exceeded was defined. |
| This is a functional extremum problem with a boundary constraint. |
| This data is associated with its measuring point, its event type, its beginning, its channel, its extremum and its length. |
| Table 2 lists the times of minimum determined by the extremum fitting method with figure 2 presented as an example. |
