Propagation Ranking

The propagation ranking associates to any AF FF a ranking ⪰FθPropa\succeq^{\theta^{\mathsf{Propa}}}_F on AA by giving each argument an initial value, propagating it along attack paths, and comparing the resulting vectors, in one of three variants Propaϵ\mathsf{Propa}_\epsilon, Propa1+ϵ\mathsf{Propa}_{1+\epsilon}, Propa1→ϵ\mathsf{Propa}_{1\to\epsilon}.

Remarks

AgonProject computes this ranking for acyclic AFs only.
