Problem Definition

Recent developments in phylogenetics have provided evidences that evolutionary histories cannot always be represented as a single tree; thus, more sophisticated representations are needed. Phylogenetic networks are natural extensions of phylogenetic trees that recently gathered general consensus in literature. Let Λ be a finite set of labels, representing a set of extant species (taxa). A rooted phylogenetic N over Λ (or, simply, phylogenetic network or network) is a directed acyclic connected graph \(N =\langle V (N),A(N)\rangle\)
