An exponential tree is almost identical to a binary search tree, with the exception that the dimension of the tree is not the same at all levels. In a normal binary search tree, each node has a dimension (d) of 1, and has 2d children. In an exponential tree, the dimension equals the depth of the node, with the root node having a d = 1. So the second level can hold two nodes, the third can hold eight nodes, the fourth 64 nodes, and so on.

Famous quotes containing the word tree:
“But when the bowels of the earth were sought,
And men her golden entrails did espy,
This mischief then into the world was brought,
This framed the mint which coined our misery.
...
And thus began th’exordium of our woes,
The fatal dumb-show of our misery;
Here sprang the tree on which our mischief grows,
The dreary subject of world’s tragedy.”
—Michael Drayton (1563–1631)
