Select Best Trajectory by Distance and Length — select.closest.longest.trajectory • gflow

Among trajectories closest to a target vertex, selects the one with the most vertices. This is useful when multiple trajectories are equally close to a landmark and a tiebreaker is needed.

Usage

select.closest.longest.trajectory(
  trajectories,
  traj.dists,
  distance.tolerance = 1e-09
)

Arguments

trajectories: A list of integer vectors, each representing a trajectory.
traj.dists: Output from trajectory.distances.to.vertex.
distance.tolerance: Numeric tolerance for considering distances equal. Trajectories within this tolerance of the minimum distance are considered tied. Default is 1e-9.

Value

A list with components:

best.idx: Index of the selected trajectory in the input list.
trajectory: The selected trajectory (integer vector of vertices).
min.distance: Distance from the selected trajectory to the target.
n.vertices: Number of vertices in the selected trajectory.
n.tied: Number of trajectories tied at the minimum distance.
tied.idx: Indices of all tied trajectories.
