Our Discussion:

This paper raises a number of interesting issues relative to the estimation of parameters of whole-cell models. The challenge here is obviously the underdetermination of the problem when the number of parameters is very large. This challenge calls both for the development of new parameter estimation algorithms and for innovative software implementations. This paper describes the challenge and the best performing solutions proposed in the context of the DREAM 8 challenge.
