... indices in their binary representation (see Figure 6.b). The lowest common ancestor 2 (binary 10) is designated by the longest common initial substring of 9 (binary 1001) and 11 (binary 1011). ... Strategy for keeping storage trees as balanced as possible Binary trees Our structure -sharing scheme depends on represented feature sets as binary trees. A tree consists of cells...
