“…• In the constellations approach, the uncertainty is in the topology of the graph (Dung & Thang, 2010;Li, Oren, & Norman, 2011;Hunter, 2012;Fazzinga, Flesca, & Parisi, 2013;Li, Oren, & Norman, 2013;Hunter & Thimm, 2014a;Dondio, 2014;Polberg & Doder, 2014;Doder & Woltran, 2014;Fazzinga, Flesca, & Parisi, 2015;Liao & Huang, 2015;Hadoux, Beynier, Maudet, Weng, & Hunter, 2015;Sun & Liao, 2016;Fazzinga et al, 2016). As an example, this approach is useful when one agent is not sure what arguments and attacks another agent is aware of, and so this can be captured by a probability distribution over the space of possible argument graphs.…”
