## Figure 8.
Validation of running time. (a) Total running time divided by n log^{2 }n.. (b) The percent of time used on the three parts of the algorithm. The left figure
shows the total running time divided by n log^{2 }n showing that the theoretical running time is achieved in the implementation. The right
figure shows the percent of time used on the three parts of the algorithm: constructing
the HDT of the second tree, coloring the leaves in the first tree, and updating the
HDT accordingly. Constructing the HDT takes a considerable part of the time, but as
the trees grow, updating the HDT takes a larger part. The plots show the average over
50 experiments for each size n.
