     ↳Dependency Pair Analysis

R contains the following Dependency Pairs:

PLUS(s(x), y) -> PLUS(x, y)
PLUS(s(x), y) -> PLUS(p(s(x)), y)
PLUS(s(x), y) -> P(s(x))
PLUS(x, s(y)) -> PLUS(x, p(s(y)))
PLUS(x, s(y)) -> P(s(y))
TIMES(s(x), y) -> PLUS(y, times(x, y))
TIMES(s(x), y) -> TIMES(x, y)
DIV(x, y) -> QUOT(x, y, y)
DIV(div(x, y), z) -> DIV(x, times(y, z))
DIV(div(x, y), z) -> TIMES(y, z)
QUOT(s(x), s(y), z) -> QUOT(x, y, z)
QUOT(x, 0, s(z)) -> DIV(x, s(z))
EQ(s(x), s(y)) -> EQ(x, y)
DIVIDES(y, x) -> EQ(x, times(div(x, y), y))
DIVIDES(y, x) -> TIMES(div(x, y), y)
DIVIDES(y, x) -> DIV(x, y)

PR(x, s(s(y))) -> DIVIDES(s(s(y)), x)
IF(false, x, y) -> PR(x, y)

Furthermore, R contains five SCCs.

Dependency Pairs:

PLUS(x, s(y)) -> PLUS(x, p(s(y)))
PLUS(s(x), y) -> PLUS(p(s(x)), y)
PLUS(s(x), y) -> PLUS(x, y)

Rules:

The following dependency pair can be strictly oriented:

PLUS(s(x), y) -> PLUS(x, y)

Additionally, the following usable rules using the Ce-refinement can be oriented:

p(0) -> 0
p(s(x)) -> x

Used ordering: Polynomial ordering with Polynomial interpretation:

POL(PLUS(x₁, x₂)) = 1 + x₁

POL(0) = 0

POL(s(x₁)) = 1 + x₁

POL(p(x₁)) = x₁

resulting in one new DP problem.
