On the Quest for an Acyclic Graph
Mikoláš Janota, Radu Gheorghe Grigore, Vasco M. Manquinho · arXiv (Cornell University) · 2017
The paper aims at finding acyclic graphs under a given set of constraints. More specifically, given a propositional formula ϕ over edges of a fixed-size graph, the objective is to find a model of ϕ that corresponds to a graph that is acyclic. The paper proposes several encodings of the problem and compares them in an experimental evaluation using stateof-the-art SAT solvers.
