pymoo: Multi-objective Optimization in Python

====================================================================

Our open-source framework pymoo offers state of the art single- and multi-objective algorithms and many more features

related to multi-objective optimization such as visualization and decision making.

.. _Installation:

Installation

********************************************************************************

First, make sure you have a Python 3 environment installed. We recommend miniconda3 or anaconda3.

The official release is always available at PyPi:

.. code:: bash

    pip install -U pymoo

For the current developer version:

.. code:: bash

    git clone https://github.com/anyoptimization/pymoo

    cd pymoo

    pip install .

Since for speedup, some of the modules are also available compiled, you can double-check

if the compilation worked. When executing the command, be sure not already being in the local pymoo

directory because otherwise not the in site-packages installed version will be used.

.. code:: bash

    python -c "from pymoo.util.function_loader import is_compiled;print('Compiled Extensions: ', is_compiled())"

.. _Usage:

Usage

********************************************************************************

We refer here to our documentation for all the details.

However, for instance, executing NSGA2:

.. code:: python

    from pymoo.algorithms.moo.nsga2 import NSGA2

    from pymoo.problems import get_problem

    from pymoo.optimize import minimize

    from pymoo.visualization.scatter import Scatter

    problem = get_problem("zdt1")

    algorithm = NSGA2(pop_size=100)

    res = minimize(problem,

                   algorithm,

                   ('n_gen', 200),

                   seed=1,

                   verbose=True)

    plot = Scatter()

    plot.add(problem.pareto_front(), plot_type="line", color="black", alpha=0.7)

    plot.add(res.F, color="red")

    plot.show()

A representative run of NSGA2 looks as follows:
