%X Cladograrns resemble directed Prim networks or Wagner trees, and are usually programmed by parsimony, i.e. the program searches for the least number of steps to achieve a cladistic synthesis. Large matrices can yield an almost infinite number of possible trees; and even when differences of only a few steps are involved there are numerous plausible solutions. Parsimony and other factors, such as Nelson and Platnick's assumptions, act as Occam's razor, reducing these to a manageable few.
