The Trust Region Radius

keyword:

TRUST-REGION-RADIUS (real)

The initial trust region radius is normally set internally by LANCELOT. However, the user may have good reason for overriding this value. If the user wishes to specify an initial radius, the value of the radius should follow the keyword TRUST-REGION-RADIUS. A nonpositive value will be replaced by a value chosen by LANCELOT. The default is for LANCELOT to select the initial radius.
