Which Phylogenetic Networks are Merely Trees with Additional Arcs?

Francis AR, Steel M - Syst. Biol. (2015)

Bottom Line: Here, we establish a precise and easily tested criterion (based on "2-SAT") that efficiently determines whether or not any given network can be realized in this way.Moreover, the proof provides a polynomial-time algorithm for finding one or more trees (when they exist) on which the network can be based.A number of interesting consequences are presented as corollaries; these lead to some further relevant questions and observations, which we outline in the conclusion.
