Figure 1.

Flow diagram representing the procedure in which we obtained results on the behavior of phylogenetic inference strategies. A boldface number attached to a downward arrow indicates the number of phylogenetic inference strategies generated by the box immediately above the arrow. Absence of a number indicates a value of 1. The number of strategies for a particular path from the topmost box to the bottom layer is calculated as the product of the boldface numbers visited during the traversal of the path. The number of phylogenetic inference strategies analyzed is 72, the sum over all paths from the topmost box to boxes in the bottom layer.
