List Presolve Reductions

Type: Selection

Range: The settings listed below

Default: Never

This option controls the frequency with which the reductions by the AIMMS Presolver are printed in the listing file. Possible values are:

• Never

• At first solve

• At an infeasible solve

• At every solve

The reductions that are printed to the listing file are the upper and lower bounds of the variables that are tightened by the AIMMS Presolver, and the constraints and variables that are deleted.

If the option MINLP Probing is switched on then also the nonlinear constraints that have been linearized are reported.

Note

• The options Solution Listing Column Name Style and Solution Listing Row Name Style control the style used for referencing the variables and constraints when printing the presolve reductions.
