ProblemA partial split of a set S">SS of n">nn taxa models a partial character and is denoted by A∣B">A∣BA∣B, where A">AA and B">BB are still the two disjoint subsets of taxa divided by the character. Unlike in the case of splits, we do not necessarily require that A∪B=S">A∪B=SA∪B=S; (A∪B)c">(A∪B)c(A∪B)c corresponds to those taxa for which we lack conclusive evidence regardi..
