Outline

-------

A module for different types of random walks on any directed or undirected network.

See the contained notebook for an example use. It implements random walker

models presented in [\ 1_ - 4_] using IPython's parallel-processing. The module

also provides functions to evaluate internal dynamics vs external fluctuations

as defined in [\ 2_].

Requirements

------------

* networkx_

* numpy_

.. _networkx: http://networkx.github.com/

.. _numpy: http://www.numpy.org/

Optional

~~~~~~~~

* IPython_ and 0MQ for parallel-processing. An older version that uses local

  ``multiprocessing`` is available, too.

* matplotlib_ for plotting

* tables_ for storing results

.. _IPython: http://ipython.org/

.. _matplotlib: http://matplotlib.org/

.. _tables: http://www.pytables.org/

Also take a look at the ``requirements.txt`` and ``opt-requirements.txt`` files

that you can use with ``pip`` to install the necessary packages.

    pip install -r
