Q DP problem:
The TRS P consists of the following rules:

MIN2(x, cons2(y, z)) -> MIN2(x, z)
MIN2(x, cons2(y, z)) -> MIN2(y, z)

The TRS R consists of the following rules:

le2(0, y) -> true
le2(s1(x), 0) -> false
le2(s1(x), s1(y)) -> le2(x, y)
eq2(0, 0) -> true
eq2(0, s1(y)) -> false
eq2(s1(x), 0) -> false
eq2(s1(x), s1(y)) -> eq2(x, y)
if3(true, x, y) -> x
if3(false, x, y) -> y
minsort1(nil) -> nil
minsort1(cons2(x, y)) -> cons2(min2(x, y), minsort1(del2(min2(x, y), cons2(x, y))))
min2(x, nil) -> x
min2(x, cons2(y, z)) -> if3(le2(x, y), min2(x, z), min2(y, z))
del2(x, nil) -> nil
del2(x, cons2(y, z)) -> if3(eq2(x, y), z, cons2(y, del2(x, z)))

The set Q consists of the following terms:

le2(0, x0)
le2(s1(x0), 0)
le2(s1(x0), s1(x1))
eq2(0, 0)
eq2(0, s1(x0))
eq2(s1(x0), 0)
eq2(s1(x0), s1(x1))
if3(true, x0, x1)
if3(false, x0, x1)
minsort1(nil)
minsort1(cons2(x0, x1))
min2(x0, nil)
min2(x0, cons2(x1, x2))
del2(x0, nil)
del2(x0, cons2(x1, x2))

We have to consider all minimal (P,Q,R)-chains.
By using an argument filtering and a montonic ordering, at least one Dependency Pair of this SCC can be strictly oriented.

MIN2(x, cons2(y, z)) -> MIN2(x, z)
MIN2(x, cons2(y, z)) -> MIN2(y, z)
Used argument filtering: MIN2(x1, x2)  =  x2
cons2(x1, x2)  =  cons1(x2)
Used ordering: Quasi Precedence: trivial

We have to consider all minimal (P,Q,R)-chains.
The TRS P is empty. Hence, there is no (P,Q,R) chain.
