`     ↳Dependency Pair Analysis`

R contains the following Dependency Pairs:

EQ(s(x), s(y)) -> EQ(x, y)
LE(s(x), s(y)) -> LE(x, y)
APP(add(n, x), y) -> APP(x, y)
RM(n, add(m, x)) -> IFRM(eq(n, m), n, add(m, x))
RM(n, add(m, x)) -> EQ(n, m)
IFRM(true, n, add(m, x)) -> RM(n, x)
IFRM(false, n, add(m, x)) -> RM(n, x)
MINSORT(add(n, x), y) -> IFMINSORT(eq(n, min(add(n, x))), add(n, x), y)
MINSORT(add(n, x), y) -> EQ(n, min(add(n, x)))
IFMINSORT(true, add(n, x), y) -> MINSORT(app(rm(n, x), y), nil)
IFMINSORT(true, add(n, x), y) -> APP(rm(n, x), y)
IFMINSORT(true, add(n, x), y) -> RM(n, x)
IFMINSORT(false, add(n, x), y) -> MINSORT(x, add(n, y))

Furthermore, R contains six SCCs.

Strategy:

innermost

The following dependency pair can be strictly oriented:

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

There are no usable rules for innermost that need to be oriented.

Used ordering: Polynomial ordering with Polynomial interpretation:
 POL(EQ(x1, x2)) =  x1 POL(s(x1)) =  1 + x1

resulting in one new DP problem.

app(nil, y) -> y
app(add(n, x), y) -> add(n, app(x, y))
rm(n, nil) -> nil
rm(n, add(m, x)) -> ifrm(eq(n, m), n, add(m, x))
ifrm(true, n, add(m, x)) -> rm(n, x)
ifrm(false, n, add(m, x)) -> add(m, rm(n, x))
eq(0, 0) -> true
eq(0, s(x)) -> false
eq(s(x), 0) -> false
eq(s(x), s(y)) -> eq(x, y)
min(add(n, nil)) -> n
le(0, y) -> true
le(s(x), 0) -> false
le(s(x), s(y)) -> le(x, y)

Used ordering: Polynomial ordering with Polynomial interpretation:
 POL(false) =  0 POL(if_rm(x1, x2, x3)) =  x3 POL(true) =  0 POL(rm(x1, x2)) =  x2 POL(MINSORT(x1, x2)) =  x1 + x2 POL(if_min(x1, x2)) =  x2 POL(add(x1, x2)) =  1 + x1 + x2 POL(IF_MINSORT(x1, x2, x3)) =  x2 + x3 POL(eq(x1, x2)) =  0 POL(0) =  0 POL(nil) =  0 POL(min(x1)) =  x1 POL(s(x1)) =  0 POL(le(x1, x2)) =  0 POL(app(x1, x2)) =  x1 + x2

resulting in one new DP problem.

The following dependency pair can be strictly oriented:

Additionally, the following usable rules for innermost can be oriented:

eq(0, 0) -> true
eq(0, s(x)) -> false
