Standardize variables so that each quantifier binds a unique variable . Since
variables are just dummy names , this process cannot affect the truth value of the
wff . For example , the formula VxP ( x ) V VxQ ( x ) would be converted to VxP ( x
) V ...

the variable that makes the formula true . We can eliminate the quantifier by
substituting for the variable a reference to a function that produces the desired
value . Since we do not necessarily know how to produce the value , we must
create a ...

Standardize apart the variables in the set of clauses generated in step 8 . By this
we mean rename the variables so that no two clauses make reference to the
same variable . In making this transformation , we rely on the fact that ( VxP ( x )
