SubalgebraBases :: Autosubduce

Autosubduce -- Flag for autosubduction before the Sagbi algorithm

Description

By default, the function sagbi performs autosubduction on the generators of the given subring before starting the main algorithm. This step is required in order to guarentee the correctness of the result in all cases. The output of the sagbi algorithm is often correct even when this step is skipped. Setting this flag to false may result in a performance improvement, albeit with a risk of errors.
