----------------------------------------

(0)
Obligation:
Q restricted rewrite system:
The TRS R consists of the following rules:

   eq(0, 0) -> true
   eq(0, s(X)) -> false
   eq(s(X), 0) -> false
   eq(s(X), s(Y)) -> eq(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))
   purge(nil) -> nil
   purge(add(N, X)) -> add(N, purge(rm(N, X)))

Q is empty.

----------------------------------------

(1) Overlay + Local Confluence (EQUIVALENT)
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:

   eq(0, 0) -> true
   eq(0, s(X)) -> false
   eq(s(X), 0) -> false
   eq(s(X), s(Y)) -> eq(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))
   purge(nil) -> nil
   purge(add(N, X)) -> add(N, purge(rm(N, X)))

The set Q consists of the following terms:

   eq(0, 0)
   eq(0, s(x0))
   eq(s(x0), 0)
   eq(s(x0), s(x1))
   rm(x0, nil)
   rm(x0, add(x1, x2))
   ifrm(true, x0, add(x1, x2))
   ifrm(false, x0, add(x1, x2))
   purge(nil)
   purge(add(x0, x1))


----------------------------------------

(3) DependencyPairsProof (EQUIVALENT)
Using Dependency Pairs [AG00,LPAR04] we result in the following initial DP problem.
