8.6.7. MDOSOS

MDOSOS

MindOpt applications can represent SOS (Special Ordered Set) constraints. These constraints are used to model specific types of discrete optimization problems.

Methods

get	Retrieve the int attribute value owned by the SOS constraint by name
index	Retrieve the index of this SOS constraint in the model
sameAs	Check whether this SOS constraint is the same as another SOS constraint
set	Set the value of the int attribute owned by the SOS constraint

int get(MDO.IntAttr attr)

Retrieve the int attribute value owned by the SOS constraint by name.

Parameters

MDO.IntAttr attr – Attribute name.

Returns

Property value.

int index()

Retrieve the index of this SOS constraint in the model

Returns

The index of this SOS constraint.

boolean sameAs(MDOSOS other)

Check whether this SOS constraint is the same as another SOS constraint.

Parameters

MDOSOS other – Compared SOS constraints.

Returns

Return True if the two constraints are the same.

void set(MDO.IntAttr attr, int newval)

Set the value of the int attribute owned by the SOS constraint.

Parameters

• MDO.IntAttr attr – Attribute name.

• int newval – The new value to be set.
