    • getFarthestSeedsRatio

      public double getFarthestSeedsRatio()
      Ratio (between 0 and 1) of available vehicles in the model on which
farthest nodes of the model are inserted as seeds.
      double farthest_seeds_ratio = 1;
      Specified by:
      getFarthestSeedsRatio in interface GlobalCheapestInsertionParametersOrBuilder
      Returns:
      The farthestSeedsRatio.

    • getNeighborsRatio

      public double getNeighborsRatio()
      Ratio (in ]0, 1]) of closest non start/end nodes to consider as neighbors
for each node when creating new insertions in the parallel/sequential
cheapest insertion heuristic.
If not overridden, its default value is 1, meaning all neighbors will be
considered.
The neighborhood ratio is coupled with the corresponding min_neighbors
integer, indicating the minimum number of neighbors to consider for each
node:
num_closest_neighbors =
max(min_neighbors, neighbors_ratio * NUM_NON_START_END_NODES)
This minimum number of neighbors must be greater or equal to 1, its
default value.
      double neighbors_ratio = 2;
      Specified by:
      getNeighborsRatio in interface GlobalCheapestInsertionParametersOrBuilder
      Returns:
      The neighborsRatio.

    • getMinNeighbors

      public int getMinNeighbors()
      int32 min_neighbors = 3;
      Specified by:
      getMinNeighbors in interface GlobalCheapestInsertionParametersOrBuilder
      Returns:
      The minNeighbors.

    • getUseNeighborsRatioForInitialization

      public boolean getUseNeighborsRatioForInitialization()
      Whether or not to only consider closest neighbors when initializing the
assignment. More precisely, if true, only closest neighbors (see
neighbors_ratio and min_neighbors) are considered as insertion positions
during initialization. Otherwise, all possible insertion positions are
considered.
      bool use_neighbors_ratio_for_initialization = 6;
      Specified by:
      getUseNeighborsRatioForInitialization in interface GlobalCheapestInsertionParametersOrBuilder
      Returns:
      The useNeighborsRatioForInitialization.

    • getAddUnperformedEntries

      public boolean getAddUnperformedEntries()
      Whether or not to consider entries making the nodes/pairs unperformed.
More precisely, if true, entries are created for making the nodes/pairs
unperformed, and when the cost of making a node unperformed is lower than
all insertions, the node/pair will be made unperformed. If false, only
entries making a node/pair performed are considered.
      bool add_unperformed_entries = 7;
      Specified by:
      getAddUnperformedEntries in interface GlobalCheapestInsertionParametersOrBuilder
      Returns:
      The addUnperformedEntries.
