In this page we provide several examples that should just run out of the box if you have all the dependencies installed correctly. On top of pykep you may need to install pygmo, matplotlib, scipy, pygmo_plugins_nonfree. Many example run using the commercial optimizer snopt7 (wrapped by pygmo_plugins_nonfree), in case you hacve no access to it the NLOPT optimizer slsqp as well as ipopt may be used. Both of which are shipped in the pygmo optimization suite.
Some of the examples are the outcome of research we performed for the European Space Agency and contain rather advanced optimization techniques and methods. Please quote our papers in case you find them of use in your research.
