Formula for practitioners

a(cgact(c)){1if aUnwl0otherwise\displaystyle \sum_{a \in (\cup_{c \in g} \mathit{act}(c))} \begin{cases} 1 & \text{if } a \in \mathit{Unwl} \\ 0 & \text{otherwise} \end{cases}

Unwl\mathit{Unwl} returns the set of unwanted activities.
act(c)\mathit{act}(c) returns the set of activities that occurred in case cc.

Formal Definition

Unwl(cgact(c))|\mathit{Unwl} \cap (\cup_{c \in g} \mathit{act}(c))|
