INDPRELINBIGM
Description
|
During presolve, indicator constraints can be internally replaced with regular rows (i.e. linearized) using a BigM coefficient whenever the BigM coefficient is smaller or equal to this value.

Type

Double

Default value
|
100.0

Note
|
Replacing an indicator constraint with a BigM row has a side effect on tolerances. In the indicator constraint form, the constraint part is satisfied with FEASTOL tolerance; while after changing it to BigM form, the constraint also includes the binary indicator variable (with a coefficient up to INDPRELINBIGM and an integrality tolerance of MIPTOL), therefore the constraint part of the indicator contraint is satisfied with tolerance FEASTOL+MIPTOL*INDPRELINBIGM.
