Method Detail

getBranching

IntBranching getBranching()

each IVarSelector is associated to a branching strategy

Returns:

the associated branching strategy

selectVar

AbstractVar selectVar()

the IVarSelector can be asked to return a variable

Returns:

a variable on whose domain an alternative can be set (such as a non instantiated search variable)
