  • Method Summary

    Modifier and Type
    Method
    Description
    boolean
    getAddReverseArcs()
    Add savings related to reverse arcs when finding the nearest neighbors of the nodes.
    double
    getArcCoefficient()
    Coefficient of the cost of the arc for which the saving value is being computed: Saving(a-->b) = Cost(a-->end) + Cost(start-->b) - arc_coefficient * Cost(a-->b) This parameter must be greater than 0, and its default value is 1.
    double
    getMaxMemoryUsageBytes()
    The number of neighbors considered for each node in the Savings heuristic is chosen so that the space used to store the savings doesn't exceed max_memory_usage_bytes, which must be in ]0, 1e10].
    double
    getNeighborsRatio()
    Ratio (in ]0, 1]) of neighbors to consider for each node when constructing the savings.

  • Method Details

    • getNeighborsRatio

      double getNeighborsRatio()
      Ratio (in ]0, 1]) of neighbors to consider for each node when constructing
the savings. If unspecified, its value is considered to be 1.0.
      double neighbors_ratio = 1;
      Returns:
      The neighborsRatio.

    • getMaxMemoryUsageBytes

      double getMaxMemoryUsageBytes()
      The number of neighbors considered for each node in the Savings heuristic
is chosen so that the space used to store the savings doesn't exceed
max_memory_usage_bytes, which must be in ]0, 1e10].
NOTE: If both neighbors_ratio and max_memory_usage_bytes
are specified, the number of neighbors considered for each node will be the
minimum of the two numbers determined by these parameters.
      double max_memory_usage_bytes = 2;
      Returns:
      The maxMemoryUsageBytes.

    • getAddReverseArcs

      boolean getAddReverseArcs()
      Add savings related to reverse arcs when finding the nearest neighbors
of the nodes.
      bool add_reverse_arcs = 3;
      Returns:
      The addReverseArcs.

    • getArcCoefficient

      double getArcCoefficient()
      Coefficient of the cost of the arc for which the saving value is being
computed:
Saving(a-->b) = Cost(a-->end) + Cost(start-->b)
- arc_coefficient * Cost(a-->b)
This parameter must be greater than 0, and its default value is 1.
      double arc_coefficient = 4;
      Returns:
      The arcCoefficient.
