The Penalty Parameter

keyword:

INITIIAL-PENALTY-PARAMETER (real)

If there are general constraints  present, the constraints are combined with the objective function  in an augmented Lagrangian  function (see method section). The weighting factor by which the squares of the constraints  are initially divided, the penalty parameter, may be supplied as a real number that follows the keyword

INITIAL-PENALTY-PARAMETER. A default INITIAL-PENALTY-PARAMETER 0.1
is used.
