Argumentation is a highly researched topic in the area of reasoning. However the central formalism of Dung abstract argumentation frameworks (AF)  can not handle uncertainty. So the model control argumentation framework (CAF) was introduced, which proposed as a unifying framework to capture uncertainties about the existence of arguments and attacks between arguments. Control argumentation frameworks also feature uncertain arguments and attacks and are intended specifically to model strategic scenarios from the point of view of an agent. The model divides the uncertain elements of an argumentation into a control part and an uncertain part, where the existence of elements in the control part is controlled by the agent, and the existence of elements in the uncertain part is not. The problem of controllability in control argumentation frameworks asks whether there exists a selection of arguments in the control part, such that for all selections of elements in the uncertain part a given target set of arguments satisfies a spectified set of properties. This problem was analyzed by Dimopoulos et al.  and Niskanen et al. .
The goal of this thesis is to implement CAFs into the TweetyProject library  as well as a solver for the controllability problem for a specified set of properties. This solver should use Answer Set Programming and an evalutation is expected.
