◆ addAllVarIndex()

Builder com.google.ortools.linearsolver.MPSosConstraint.Builder.addAllVarIndex ( java.lang.Iterable<? extends java.lang.Integer > values )

Variable index (w.r.t. the "variable" field of MPModelProto) of the
variables in the SOS.

repeated int32 var_index = 2;

Parameters

values The varIndex to add.

Returns: This builder for chaining.

Definition at line 877 of file MPSosConstraint.java.

◆ addAllWeight()

Builder com.google.ortools.linearsolver.MPSosConstraint.Builder.addAllWeight ( java.lang.Iterable<? extends java.lang.Double > values )

Optional: SOS weights. If non-empty, must be of the same size as
"var_index", and strictly increasing. If empty and required by the
underlying solver, the 1..n sequence will be given as weights.
SUBTLE: The weights can help the solver make branch-and-bound decisions
that fit the underlying optimization model: after each LP relaxation, it
will compute the "average weight" of the SOS variables, weighted by value
(this is confusing: here we're using the values as weights), and the binary
branch decision will be: is the non-zero variable above or below that?
(weights are strictly monotonous, so the "cutoff" average weight
corresponds to a "cutoff" index in the var_index sequence).

repeated double weight = 3;

Parameters

values The weight to add.

Returns: This builder for chaining.

Definition at line 1050 of file MPSosConstraint.java.

◆ addRepeatedField()

◆ addVarIndex()

Builder com.google.ortools.linearsolver.MPSosConstraint.Builder.addVarIndex ( int value )

Variable index (w.r.t. the "variable" field of MPModelProto) of the
