NAME

       mlpack_emst - fast euclidean minimum spanning tree

SYNOPSIS

        mlpack_emst -i string [-l int] [-n bool] [-V bool] [-o string] [-h -v]

DESCRIPTION

       This program can compute the Euclidean minimum spanning tree of a set of input points using the dual-tree
       Boruvka algorithm.

       The set to calculate the minimum spanning tree of is specified with the  ’--input_file  (-i)'  parameter,
       and the output may be saved with the ’--output_file (-o)' output parameter.

       The  '--leaf_size  (-l)'  parameter  controls  the leaf size of the kd-tree that is used to calculate the
       minimum spanning tree, and if the '--naive (-n)' option is given, then brute-force search is  used  (this
       is  typically  much slower in low dimensions). The leaf size does not affect the results, but it may have
       some effect on the runtime of the algorithm.

       For example, the minimum spanning tree of the input dataset 'data.csv' can be calculated with a leaf size
       of 20 and stored as 'spanning_tree.csv' using the following command:

       $ mlpack_emst --input_file data.csv --leaf_size 20 --output_file spanning_tree.csv

       The  output  matrix  is a three-dimensional matrix, where each row indicates an edge. The first dimension
       corresponds to the lesser index of the edge; the second dimension corresponds to the greater index of the
       edge; and the third column corresponds to the distance between the two points.

REQUIRED INPUT OPTIONS

       --input_file (-i) [string]
              Input data matrix.

OPTIONAL INPUT OPTIONS

       --help (-h) [bool]
              Default help info.

       --info [string]
              Print help on a specific option. Default value ''.

       --leaf_size (-l) [int]
              Leaf  size  in  the  kd-tree. One-element leaves give the empirically best performance, but at the
              cost of greater memory requirements.  Default value 1.

       --naive (-n) [bool]
              Compute the MST using O(n^2) naive algorithm.

       --verbose (-v) [bool]
              Display informational messages and the full list of parameters and timers at the end of execution.

       --version (-V) [bool]
              Display the version of mlpack.

OPTIONAL OUTPUT OPTIONS

       --output_file (-o) [string]
              Output data. Stored as an edge list.
