Hessian approximation successive iterations limit

Type

Integer

Range

{1..2147483647}

Default

2

This option specifies the threshold for successive iterations where update is skipped. If the update is skipped more than this number of successive iterations, the quasi-Newton approximation is reset.

Note

• This option is only used if the option Method for Hessian Computation has been set to ‘Quasi-Newton’, or to ‘Automatic’ and no Hessian is available in AIMMS.
