Tree model T1

Problem:

Tree Model T1 from Strimmer and von Haeseler.  a and b are rational numbers such that a < b.

Tree

We generate 500 replications with the Jukes-Cantor model via a software evolver from PAML package. How often a tree reconstructed via MJOIN has the same tree topology with the true tree?

Results:

The number represents a percentage which we got the same tree topology.
The numbers in the table mean succes rate for the tree model T1 for each a and b.
(l is the length of datasets and m is the number of leaves for each subtree).
Note: All CPU time for MJOIN with each a/b is less than 3 seconds.
