Logic[Canonicalize] - get a canonical representation of an expression

Calling Sequence

Canonicalize(b, alpha, form)

Parameters

b

-

Boolean expression

alpha

-

(optional) set or list of names

form

-

(optional) expression of the form form=fname

Description

• 

The Canonicalize command converts the given boolean expression to a canonical form.

• 

The canonical form used is determined by the form=fname option. The default value for this option is DNF.

• 

The canonical form is given with respect to the names given in alpha.  Note that alpha is necessary when the form chosen is CNF or DNF.

Available Canonical Forms

  

The following is a list of available canonical forms.

• 

MOD2  - The Boolean expression is converted to its equivalent modulo 2 canonical form.

• 

CNF - The conjunctive normal form  is returned.

• 

DNF - The disjunctive normal form  is returned.

Examples

withLogic:

Canonicalizea &and b,a,b,c

a &and b &and c &or a &and b &and &notc

(1)

Canonicalizea &xor b,form=MOD2

a+b

(2)

Canonicalizea &xor b,a,b,form=CNF

a &or b &and &nota &or &notb

(3)

Canonicalizea &xor b,a,b,form=DNF

a &and &notb &or b &and &nota

(4)
