`     ↳Dependency Pair Analysis`

R contains the following Dependency Pairs:

AND(xor(x, y), z) -> XOR(and(x, z), and(y, z))
AND(xor(x, y), z) -> AND(x, z)
AND(xor(x, y), z) -> AND(y, z)
IMPL(x, y) -> XOR(and(x, y), xor(x, T))
IMPL(x, y) -> AND(x, y)
IMPL(x, y) -> XOR(x, T)
OR(x, y) -> XOR(and(x, y), xor(x, y))
OR(x, y) -> AND(x, y)
OR(x, y) -> XOR(x, y)
EQUIV(x, y) -> XOR(x, xor(y, T))
EQUIV(x, y) -> XOR(y, T)
NEG(x) -> XOR(x, T)

Furthermore, R contains one SCC.

Dependency Pairs:

AND(xor(x, y), z) -> AND(y, z)
AND(xor(x, y), z) -> AND(x, z)

Rules:

xor(x, F) -> x
xor(x, neg(x)) -> F
xor(x, x) -> F
and(x, T) -> x
and(x, F) -> F
and(x, x) -> x
and(xor(x, y), z) -> xor(and(x, z), and(y, z))
impl(x, y) -> xor(and(x, y), xor(x, T))
or(x, y) -> xor(and(x, y), xor(x, y))
equiv(x, y) -> xor(x, xor(y, T))
neg(x) -> xor(x, T)

The following dependency pairs can be strictly oriented:

AND(xor(x, y), z) -> AND(y, z)
AND(xor(x, y), z) -> AND(x, z)

There are no usable rules using the Ce-refinement that need to be oriented.

Used ordering: Polynomial ordering with Polynomial interpretation:
 POL(xor(x1, x2)) =  1 + x1 + x2 POL(AND(x1, x2)) =  x1

resulting in one new DP problem.

Dependency Pair:

Rules:

xor(x, F) -> x
xor(x, neg(x)) -> F
xor(x, x) -> F
and(x, T) -> x
and(x, F) -> F
and(x, x) -> x
and(xor(x, y), z) -> xor(and(x, z), and(y, z))
impl(x, y) -> xor(and(x, y), xor(x, T))
or(x, y) -> xor(and(x, y), xor(x, y))
equiv(x, y) -> xor(x, xor(y, T))
neg(x) -> xor(x, T)

Using the Dependency Graph resulted in no new DP problems.
