(0) Obligation:

Q restricted rewrite system:
The TRS R consists of the following rules:

s1(s1(s0(s0(x)))) → s0(s0(s0(s1(s1(s1(x))))))

Q is empty.

(1) Overlay + Local Confluence (EQUIVALENT transformation)

The TRS is overlay and locally confluent. By [NOC] we can switch to innermost.

(2) Obligation:

Q restricted rewrite system:
The TRS R consists of the following rules:

s1(s1(s0(s0(x)))) → s0(s0(s0(s1(s1(s1(x))))))

The set Q consists of the following terms:

s1(s1(s0(s0(x0))))

(3) DependencyPairsProof (EQUIVALENT transformation)

Using Dependency Pairs [AG00,LPAR04] we result in the following initial DP problem.

(4) Obligation:

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

S1(s1(s0(s0(x)))) → S1(s1(s1(x)))
S1(s1(s0(s0(x)))) → S1(s1(x))
S1(s1(s0(s0(x)))) → S1(x)

The TRS R consists of the following rules:

s1(s1(s0(s0(x)))) → s0(s0(s0(s1(s1(s1(x))))))

The set Q consists of the following terms:

s1(s1(s0(s0(x0))))

We have to consider all minimal (P,Q,R)-chains.
