Figure 1: A Concept of a mapping by a character type. (A) A concept of f1
1M − 5M are comprised of 5 R and 1 L and each character attaches a leaf
node of a rooted phylogenetic tree under a hypothesis that the evolutionary
rate is constant. Numbers in ascending order are assigned from the root to leaf
nodes as time point t. In f1, after a value in a circle is assigned to iM , values
in circles are summed. (B) Concepts of gx and hx . In gx after hx maps
characters in a square to a value in a triangle, values in triangles are mapped
to a value in a circle.
