Abstract:
fixed size m (= 256 bits). But this data structure may be
implemented in several different ways, for instance as a set of
tables representing the currently relevant parts of the tree.
We use a sequence of integer numbers as indexes for the nodes
(values) in the tree. To avoid parentheses, commas, and semicolons
we write for instance: "123" for the sequence of 3 numbers "1", "2",
and "3". In what follows, in all our examples of integer sequences,
we will not use numbers that require 2 or more digits (that is,
numbers > 9).
The sequences of integers are used to index values in a tree: x_a is
the value at the node with position (address) a. In other words, the
nodes (and their values) are denoted as x_a, where a is a sequence of
integer numbers. The tree has a root x (x_a where a = epsilon is the
empty sequence). The children of x are x_1, x_2, x_3, ..., x_N,
where k = 1..N is a singleton list, that is a list with only one
number. If x_a is a node in the tree, then the children of x_a all
have the form x_a', where a'=a;i is a the concatenation of a and an
integer i. The value x_a'= x_a; i=x_(a;i) is calculated as G(x_a,i).
