	Boolean logic - Wikipedia, the free encyclopedia
		Boolean logic is a complete system for logical operations.
		Boolean logic is also used for circuit design in electrical engineering; here 0 and 1 may represent the two different states of one bit in a digital circuit, typically high and low voltage.
		Circuits are described by expressions containing variables, and two such expressions are equal for all values of the variables if, and only if, the corresponding circuits have the same input-output behavior.

		The circuit c' being evaluated by a remote host, it is important to minimize the impact of encryption on the circuit size, measured by its number of logical gates.
		Moreover, polynomials are not as expressive as Boolean circuits.
		Boolean circuits can be protected from confidentiality and integrity attacks using three different encryption techniques: circuit encryption (our approach from Section 2), truth table encryption, and gate-level encryption [36], [19].

		Boolean circuits are oblivious - they perform the same sequence of operations independently of the input (i.e.
		On the other hand, the key reason why Boolean circuits were used as the computation model for secure function evaluation protocols (rather than, e.g., a Turing machine) is their obliviousness.

		While Boolean 6-argument functions are, in my opinion, also very simple-minded (in relation to the mass of non-Boolean problems in Genetic Programming and Genetic Programming II), when one travels in the world of the trivial, the evidential value of the six argument Boolean functions surely far exceeds that of the three argument domain.

	Element-by-element Boolean Operators - Untitled
		The truth of the boolean expression is computed by combining the truth values of the corresponding elements of the component expressions.
		Like comparison operations, each element of an element-by-element boolean expression also has a numeric value (1 if true, 0 if false) that comes into play if the result of the boolean expression is stored in a variable, or used in arithmetic.
		This behavior is necessary for the boolean operators to work as described for matrix-valued operands.
