tool_calls: name: read_data
arguments: label: D4
type_guessed: string

tool: D4: Generates a random tree

Synopsis
--------

%s [-cdhsx]

Input
-----

None

Output
------

The generated tree. Branches are "grown" using exponentially distributed
lengths. If the length exceeds the time limit, growth stops; otherwise the
lineage splits in two, and the process is repeated on the children.

Options
-------

    -d <float>: sets the maximum depth (time limit). Default: 3.0
    -h: print this message and exit
    -l <float>: sets the average branch length (default: 1.0)
    -s  <int>: sets the pseudorandom number generator's seed
    0.1)

Examples
--------

# Generate a random tree

$ %s
