This paper draws heavily on the classical field of the analysis of boolean functions, which for our purposes essentially began with the seminal paper of Kahn, Kalai and Linial [KKL88], which proved that every balanced boolean function must have an influential variable (see Section 10). Since then, a ...

In this way, we assume it is possible to define the system completely and build the function which represents it. However, this is not always feasible.
