Comparison between the core set approach and standard methods. (a) The core set tree in which MP gives a single solution. (b) The final tree formed by preserving the core set tree and without any alternative phylogenetic positions in the inclusion of the excluded sequences. (c) One of MP tree (PAUP*) formed without preserving the core set tree. (c) SP tree (TCS) formed without preserving the core set tree.
