Multistart Range Unbounded Variable

Type

Floating point number

Range

[0,1e20]

Default

1e20

This option specifies the maximum range that an unbounded variable can take when determining new start points. If a variable is unbounded in one or both directions, then new start point values are restricted by the option. If x is such a variable, then all initial values satisfy

max{ bL, x0 - η/2 } ≤ x ≤ min{ bU, x0 + η/2 },

where x0 is the initial value of x provided by the user, bL and bU are the variable bounds (possibly infinite) on x and η is the value of this option.

This option has only effect if the option Multistart is switched on.
