Larry Bull
2020 arXiv   pre-print
This paper introduces a modified form of the NK model for exploring distributed control in complex systems such as organisations, social networks, collective robotics, etc.  ...  The NK model has been used widely to explore aspects of natural evolution and complex systems.  ...  The NKD model is introduced as a generalisation of the NKCS model to enable the exploration of distributed control structures within the space of NK models.  ...
