The query itself is considered as a Boolean expression whose components are 2-tuples < ti, ci >belonging to the set, TxS; ti [member of] T., where ci is a value of the linguistic variable "Relevance", associated to a limit semantics .
What is necessary is that the Boolean expression should be reduced to its minimal form (MFS), and then draw the Reduced Markov Graph (RMG) from MFS or MCV.
The Boolean expression of the constant bit [X.sup.i.sub.L,15] has the same general form as that of the balanced bit [X.sup.i+14.sub.R,0].

For example, Figure 1 shows the complete binary tree (Figure 1(a)) and the OBDD (Figure 1(b)) for the Boolean expression W = [x.sub.1] * [x.sub.2] + [x'.sub.1] * [x.sub.3] with the variable order n : [x.sub.3] > [x.sub.2] > [x.sub.1].
The boolean adjacent vertex search over a graph is a more general operation, which searches for all adjacent vertices by a boolean expression. There are disjunction, conjunction and negation three basic operations in boolean expression .
A logical query is the action of evaluating a Boolean expression concerning tuples and relations.
Check constraints place specific data value restrictions on the contents of a column through the specification of a Boolean expression. The expression is explicitly defined in the table DDL and is formulated in much the same way that SQL WHERE clauses are formulated.
(i) Constrained simple sequence expression (CSSE) is formed by Boolean expression, repeat operator, and cycle delay operator.
