Implements additional models, simulation tools, and interfaces as extensions to 'SPOT'. It provides tools for hyperparameter tuning via 'keras/tensorflow', interfacing 'mlr', for performing Markov chain simulations, and for sensitivity analysis based on sequential bifurcation methods as described in Bettonvil and Kleijnen (1996). Furthermore, additional plotting functions for output from 'SPOT' runs are implemented. Bartz-Beielstein T, Lasarczyk C W G, Preuss M (2005) doi:10.1109/CEC.2005.1554761.
