    • getVarIndexList

      public java.util.List<java.lang.Integer> getVarIndexList()
       Variable index (w.r.t. the "variable" field of MPModelProto) of the
 variables in the SOS.
      repeated int32 var_index = 2;
      Specified by:
      getVarIndexList in interface MPSosConstraintOrBuilder
      Returns:
      A list containing the varIndex.

    • getVarIndexCount

      public int getVarIndexCount()
       Variable index (w.r.t. the "variable" field of MPModelProto) of the
 variables in the SOS.
      repeated int32 var_index = 2;
      Specified by:
      getVarIndexCount in interface MPSosConstraintOrBuilder
      Returns:
      The count of varIndex.

    • getVarIndex

      public int getVarIndex​(int index)
       Variable index (w.r.t. the "variable" field of MPModelProto) of the
 variables in the SOS.
      repeated int32 var_index = 2;
      Specified by:
      getVarIndex in interface MPSosConstraintOrBuilder
      Parameters:
      index - The index of the element to return.
      Returns:
      The varIndex at the given index.

    • getWeightList

      public java.util.List<java.lang.Double> getWeightList()
       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;
      Specified by:
      getWeightList in interface MPSosConstraintOrBuilder
      Returns:
      A list containing the weight.

    • getWeightCount

      public int getWeightCount()
       Optional: SOS weights. If non-empty, must be of the same size as

      Returns:
      The count of weight.
