2 SEEK
  Syntax:   SEEK nloop [devs]
  where:    nloop  is the number of calls made in the search
            devs   is the number of deviations each side of the parameter
  Defaults: devs = 3

  Make a  random  search in  all  variable  parameters for  the function
  minimum. `SEEK' does a uniform  search within `devs' times the current
  step  size for  each  parameter.  Each new  minimum  found  shifts the
  parameters and the centre of the search.
