    Delucchi, Emanuele ; Hoessly, Linard ; Paolini, Giovanni

    In: Systematic Biology, 2020, vol. 69, no. 3, p. 557–565

    We answer two questions raised by Bryant, Francis, and Steel in their work on consensus methods in phylogenetics. Consensus methods apply to every practical instance where it is desired to aggregate a set of given phylogenetic trees (say, gene evolution trees) into a resulting, “consensus” tree (say, a species tree). Various stability criteria have been explored in this context, seeking...
