> Complex systems are sometimes characterized by hybrid functions consisting of both
> continuous and discrete variables—i.e., so-called “concrete” multivariate functions in
> the sense of D. Knuth. Gradient-based operators from classical sensitivity analysis are
> not applicable to a broad class of such complex systems due to the presence of discrete
> variables in the mix. The “nabladot” operator for hybrid functions of continuous
> and discrete variables is defined and illustrated with examples from complex social
> and technological systems. Results show new features of complex systems previously
> unavailable through extant classical approaches.
