        Py-BOBYQA is a flexible package for solving bound-constrained general objective minimization, without requiring derivatives of the objective. It is a Python implementation of the BOBYQA algorithm by Powell. Py-BOBYQA is particularly useful when evaluations of the objective function are expensive and/or noisy.
        
        More details about Py-BOBYQA can be found in our paper: C. Cartis, J. Fiala, B. Marteau and L. Roberts, `Improving the Flexibility and Robustness of Model-Based Derivative-Free Optimization Solvers <https://arxiv.org/abs/1804.00154>`_, technical report, University of Oxford, (2018).
        
        The original paper by Powell is: M. J. D. Powell, The BOBYQA algorithm for bound constrained optimization without derivatives, technical report DAMTP 2009/NA06, University of Cambridge (2009), and the original Fortran implementation is available `here <http://mat.uc.pt/~zhang/software.html>`_.
        
        If you are interested in solving least-squares minimization problems, you may wish to try `DFO-LS <https://github.com/numericalalgorithmsgroup/dfols>`_, which has the same features as Py-BOBYQA (plus some more), and exploits the least-squares problem structure, so performs better on such problems.
        
        Documentation
        -------------
        See manual.pdf or `here <http://people.maths.ox.ac.uk/robertsl/pybobyqa>`_.
        
        Requirements
        ------------
        Py-BOBYQA requires the following software to be installed:
        
        * Python 2.7 or Python 3 (http://www.python.org/)
        
        Additionally, the following python packages should be installed (these will be installed automatically if using *pip*, see `Installation using pip`_):
        
        * NumPy 1.11 or higher (http://www.numpy.org/)
        * SciPy 0.18 or higher (http://www.scipy.org/)
        * Pandas 0.17 or higher (http://pandas.pydata.org/)
        
        Installation using pip
        ----------------------
        For easy installation, use `pip <http://www.pip-installer.org/>`_ as root::
        
            $ [sudo] pip install Py-BOBYQA
        
        or alternatively *easy_install*::
        
            $ [sudo] easy_install Py-BOBYQA
        
        If you do not have root privileges or you want to install Py-BOBYQA for your private use, you can use::
        
            $ pip install --user Py-BOBYQA
        
        which will install Py-BOBYQA in your home directory.
        
        Note that if an older install of Py-BOBYQA is present on your system you can use::
        
            $ [sudo] pip install --upgrade Py-BOBYQA
        
        to upgrade Py-BOBYQA to the latest version.
        
        Manual installation
        -------------------
        Alternatively, you can download the source code from `Github <https://github.com/numericalalgorithmsgroup/pybobyqa>`_ and unpack as follows:
        
         .. code-block:: bash
        
            $ git clone https://github.com/numericalalgorithmsgroup/pybobyqa
            $ cd pybobyqa
        
        Py-BOBYQA is written in pure Python and requires no compilation. It can be installed using:
        
         .. code-block:: bash
        
            $ [sudo] pip install .
        
        If you do not have root privileges or you want to install Py-BOBYQA for your private use, you can use:
        
         .. code-block:: bash
        
            $ pip install --user .
        
        instead.
        
        To upgrade Py-BOBYQA to the latest version, navigate to the top-level directory (i.e. the one containing :code:`setup.py`) and rerun the installation using :code:`pip`, as above:
        
         .. code-block:: bash
        
            $ git pull
            $ [sudo] pip install .  # with admin privileges
        
        Testing
        -------
        If you installed Py-BOBYQA manually, you can test your installation by running:
        
         .. code-block:: bash
        
            $ python setup.py test
        
        Alternatively, the HTML documentation provides some simple examples of how to run Py-BOBYQA.
        
        Examples
        --------
        Examples of how to run Py-BOBYQA are given in the `documentation <http://people.maths.ox.ac.uk/robertsl/pybobyqa>`_, and the `examples <https://github.com/numericalalgorithmsgroup/pybobyqa/tree/master/examples>`_ directory in Github.
        
        Uninstallation
        --------------
        If Py-BOBYQA was installed using *pip* you can uninstall as follows:
        
         .. code-block:: bash
        
            $ [sudo] pip uninstall Py-BOBYQA
        
        If Py-BOBYQA was installed manually you have to remove the installed files by hand (located in your python site-packages directory).
