Presolve Numeric Switch

Type

Selection

Range

The settings listed below

Default

Automatic

This option controls whether the AIMMS Presolver should focus on precision in numerically difficult problems, e.g., problems with large matrix coefficients or large (finite) variable bounds. Possible values are:

• Off

• Automatic

• On

Focussing on precision might have a negative impact on the performance. At the default setting, AIMMS makes an automatic choice based on the matrix coefficients and variable bounds.
