Now i can generate runtime/support figures

However, i cannot answer, what patterns i generate. Because the number of patterns is millions.

The naive way is to show some representative pattern.

One of the common is to selected the long patterns.

However, I dont know which patterns are longer, because the logs only show the pieces of vpatterns

The reason is we use the fast-grow.

In the fast grow, when we link vp-a to vp-b, we dont know how long vp-a can increase.

In a DFS process, can we know the distance betweeen each node to the leaf？

The challenge is because, we cannot keep all the tree in memory, because the tree is so huge
